4 Description of Measuring Principle

The physical measurement principles applied in the BioProTT™ flow measurement system

are described in this chapter.

The BioProTT™ flow measurement system uses the ultrasonic transit-time method (TT =

transit-time) which delivers precise flow values in tube systems and pipes.

The ultrasonic converters (piezoceramics) in the flow sensors transmit high-frequency

acoustic signals in and against the flow direction. The time difference between these

signals is proportional to the volumetric flow.

The basic principle is explained below.

Receiver

Transmitter A

Tube

Flow

a

Figure 1: Principle of ultrasonic flow measurement (simplified using only two ceramics)

One piezoceramic (A) is excited by a set of high-frequency vibrations and transmits

ultrasonic waves to a second opposing piezoceramic (B) that acts as a receiver. The

piezoceramics are arranged at a specific angle α in relation to the flowing medium. The

transit time is influenced by the medium. The flow velocity of the medium can be

calculated using the measured transit time differences. The flow in liters per minute is

established using the known cross-section of the tube being scanned by ultrasonic

transmission.

Four ultrasound converters in a crosswise arrangement transmit high-frequency sound

signals alternately in and against the direction of the flow. The transit time for each

impulse is measured; the transit-time difference between the upstream and downstream

movement of the impulses is proportional to the volumetric flow.

6 Initial Set Up

In this chapter some basic consideration about integration of the BioProTT flow meters are

given and appropriate schematics of power supply and wiring of current loops are shown.

6.1 Important Current Loop Definitions

Generally, devices in 4-20 mA environments can be classified based on the current source

of the 4-20 mA loop as “active” or “passive”. Passive devices or sensors rely on (external)

loop power, whereas active devices are powering the current loop.

With respect to the 2-/4-wire classification of sensors, as a rule of thumb, one can assume

that 2-wire sensors are usually working in passive mode, whereas 4-wire sensors can

usually support the signal current loop being passive or active.

The BioProTT™ flow measurement system supports passive and active modes of

operation for flow and RSS current loop – see figure below. However, the flow meter

always needs power to operate!

Figure 2: BioProTT™ flow meter supporting “passive” loop configuration (example: flow)


Figure 3: BioProTT™ flow meter supporting “active” loop configuration (example: flow)

The figures below show some of the electrical design of the BioProTT™ flow meters

which is important to properly wire the system. The pin assignment corresponds to the pins

as outlined in the following chapters.

Figure 4: BioProTT™ flow meter schematics with focus on power supply (w/o DIN rail variant)


Figure 5: BioProTT™ FlowTrack DINrail schematics with focus on power supply

6.2 Powering of BioProTT™ Flow Meter

The flow meter works with DC power, which can be supplied with

The power supply unit shipped with the system using the power socket or

With an external 24 V DC (±10%) power supply delivering at least 300 mA and

continuously short circuit protected.

o DC power can be supplied either through PIN 1/3 of the Power, Flow or

RSS socket on BioProTT™ FlowTrack and BioProTT™ FlowTrack plus.

o BioProTT™ FlowTrack DINrail can be supplied by DC power via PIN 1/2

of the terminal block or PIN 1/3 of the Power socket.


o This option is e.g. useful, when connecting it to a process control and

centrally powering the devices on or off. In case power is provided via the

Flow or RSS socket or the terminal block, the on/off button is no longer

“active”, i.e. the flow meter will start up as soon as power is available. In

case of a device error the power supply must be turned off.

When power is supplied via the power socket the on/off switch is used

to power on the flow meter otherwise the on/off switch does not have

an effect.

Ensure that there are no conflicting power sources/voltages applied to

Pin 1 and Pin 3 of either of the Power, Flow or RSS socket, as they are

internally bridged between the sockets.

For the BioProTT™ FlowTrack DINrail, please ensure this similarly

between Pin 1 and Pin3 of the Power socket and Pin 1 and 2 of the

terminal block.

6.3 Powering Over Analog Sockets

Below pin assignments and cable colors for flow meters with round connectors for Power,

Flow and RSS sockets are shown.

6.5 Current Loop(s) powered by External Supply, e.g. from PCS

In this set-up, the flow meter current loop does not have to be powered by the flow

measurement system, as it is already being supplied with an external power supply, e.g.

using either power from a signal processing card of a PCS or separate power supply.

From a flow meter perspective the current loop is “passive”.

For details see the circuit diagrams as follows and observe the wiring instructions.

7.3.4 Remote Zero

BioProTT™ FlowTrack DINRail devices with software version SW 3.0 or later have an

integrated “Remote Zero” option to correct the offset by remote control switch. Please see

chapter ZERO ADJUSTMENT for correct zeroing conditions.

The flow offset correction can be performed by pushing the “Zero adjustment” button on

the panel or additionally by generating a direct current voltage pulse by a switch on PIN

10. The digital input for remote zero accepts pulses of 24 V DC ± 10% and has an internal

current consumption of < 25 mA.


7.3.4.1 Electrical Connection using BioProTT Power Supply

Figure 28: Drill template – values in [mm] and [inch]

7.5.2 Installation of Flow Sensor Extension Cable (IP 68 at panel)

The female socket (ODU Type G82B0C-P16LFG0-000L) of the flow sensor extension

cable can be mounted in the cabinet wall with a thickness up to 3 mm (0.12 inch). In order

to achieve the specified IP rating, the special ODU nutdriver for slotted mounting nut type

702 098 001 000 000 must be used. The maximum torque value is 4.5 Nm.

The male plug is inserted in the sensor port of the BioProTT™ FlowTrack plus. The panel

cut out panel is indicated below. The red marks indicate the correct orientation of the

connection.


Figure 29: Panel cut out in cabinet in [mm]

Please use the provided cap to protect the plug from dust etc. and achieve above IP rating

when no sensor is connected.

Please ensure that only one extension cable is used for connecting a flow sensor.

7.5.3 De-Installation of Flow Meter and Extension Cable

If the flow meter needs to be un-mounted from the panel, please disconnect all electrical

connections and open only the screw nuts accessible from inside the panel which fix the

faceplate of the device to the panel. Do not loosen any of the four cross-head screws on the

front of the device.

For de-installation of the sensor extension cable, please open screw nut of socket

accessible from front of panel.

When removing the device and cable e.g. for servicing please perform the mounting steps

in reverse order. In case of remounting the tightness of the once compressed gasket may be

compromised.


8 Performing Measurements on Tubing Systems using

BioProTT™ Clamp-On Transducers

8.1 Installation of the BioProTT™ Clamp-On Transducer

The Clamp-On transducer and the extension lines contain a push and pull locking

mechanism to avoid unintended disconnection. This permits the simple insertion and

locking. Unlocking of the connector is performed by pulling on the connector housing.

Make sure you are using the tubing, medium and temperature for which the

transducer was calibrated. The stated measurement accuracy cannot be

guaranteed if the measurements are carried out using tubing that differs in

size, wall thickness or material from the tubing on which the factory

calibration was performed. If measuring with at a different temperature or

with a different medium than the factory calibration, measurement errors

may occur unless adjustments are made by performing a custom calibration

on site and adjusting the calibration factor.

The calibration parameters are listed in the calibration report supplied with

the transducer.

Ensure that the sensor surface and tubing are clean for good coupling.

Select a location so that bubbles cannot accumulate, like below the highest

point of the overall tubing line.

8.2 Clamping Flow Sensor onto Tube

The 16-pin circular connector of the BioProTT™ Clamp-On Transducer is connected to

the BioProTT™ flow meter (see e.g. VIEW OF FRONT AND REAR). The transducer is

then clamped to the tube.

To obtain a positive flow value, make sure the arrow is pointing in the flow

direction.


Clamp the transducer onto the tube as follows:

Figure 30: Clamping onto tube

1. Open the spring lock and lift up the cover.

2. Insert the tube into the recess provided.

3. Close the lid by applying gentle pressure until the spring lock snaps into place.

4. Please note: the tubing should fit snugly in the transducer and should not be loose.

If the Clamp-On Transducer is used at significantly different parameters

compared to the calibration, like medium temperatures, this can lead to

inaccurate measurement results.

Please note: Customer-specific calibrations can also be carried out on request. Please

contact our SUPPORT AND SERVICE DEPARTMENT for further details.

8.3 Measurement Accuracy and Tube Arrangement

Accuracy ± 3% of reading ± max. 20 ml/min, for all

transducer sizes up to 1/2 x 1/8”

The accuracy has been confirmed under the following reference conditions:

Liquid temperature calibration temperature ±5°C (± 9° F)

Ambient temperature 20°C ±5°C (68° ± 9° F)

Straight inlet section 10 x ID of tubing, fully developed flow profile

Tubing Raumedic-ECC-Blood Line PVC

Acoustic couplant applied

Calibration factor 1.00


Figure 31: Accuracy graph

Optimized Accuracy:

As the measurement allows a maximal flexibility with respect to positioning the sensor the

given accuracy is a standard under the reference conditions. Certain setups allow higher

levels of accuracy and can be evaluated by a factory calibration certificate on customer

request.

Please also observe the steps below to ensure optimal measurement conditions.

Ensure a straight lead-in and run-on area (“straight inlet”):

To prevent turbulence and the associated measurement inaccuracies, it is

recommended to stretch the tube out straight in the area where it is clamped.

Notes on measurement accuracy:

Place the sensor on straight part of the tubing to avoid measurement in areas of

recirculation, vortices or spin (preferably at least 6 inches before and behind the

sensor.)

Figure 32: Using Clamp-On Transducer on straight part of tubing

Allow the sensor to reach a stable temperature profile before pressing the offset adjust

button; e.g. if the sensor has ambient temperature and the liquid medium a different

temperature, it usually takes a few minutes until a stable temperature profile is

reached.

Use only the specified tubing.

Keep to the specified temperature range of the liquid:

calibration temperature ±5°C (± 9° F).

Make sure that there is sufficient acoustic coupling (see next chapter).


8.4 Received Signal Strength (RSS / Acoustic Coupling)

The received signal strength (RSS) of the ultrasound beam is an indication of the ultrasonic

signal transmission quality through liquid, tube and sensor. In this context the RSS value is

an indication for acoustic coupling. A sufficient acoustic coupling is a pre-requisite for

accurate measurements. Please ensure that the right calibration table with the correct table

and medium is selected.

Sufficient acoustic coupling is reached when the indicated RSS value is greater than

50%. Below 50% the flow measurement result is considered to be inaccurate and is

no longer shown on the different interfaces.

Note: The RSS value is shown on the display or indicated on analog and digital

interfaces when a valid sensor is connected.

8.5 Use of Acoustic Couplant

In order to ensure good repeatability of the flow measurement, acoustic couplant should be

applied to the tube before use. This is especially important when soft tubing (like e.g.

silicone) with a low wall thickness is used. Fitting this tubing into the measurement

channel might lead to concave folding of the tubing wall and misalignment (low coupling,

acoustic focuses) to the active sensor areas. A couplant ensures an easy slip of the tube in

the channel and provides repeatable alignment of the tubing wall.

To ensure optimal measurement em-tec will provide support about the use of couplant for

your specific tubing- sensor system.

Note: It will be shown in the calibration table and, if requested, in the calibration certificate

if a sensor was calibrated with or without the specified couplant. Please make sure that

your measurements are performed accordingly. Otherwise over amplification or too low

coupling might occur.

If deterioration in the coupling is evident e.g. during long-term measurements, this is

normally a sign that the couplant is drying out. To prevent failure of the measurement,

refresh the couplant on time.

Commercially available water based ultrasonic couplants can quickly dry out and lead to

poorer acoustic coupling. If other long time couplants e.g. vaseline are used, please ensure

compatibility with tubing and sensor material and follow manufacturer’s instructions.

To ensure optimal measurement and material compatibility em-tec can provide support to

identify the right couplant for your specific tubing, sensor and process requirements. If

necessary, couplant may also be used during calibration. Couplants distributed by em-tec

are available on request.


8.6 Zero Adjustment

Zero adjustment must be carried out before the start of every measurement to avoid

possible offsets of measured values.

When doing this, the transducer should be clamped at the right location on the tube. The

tube must be filled with fluid and the fluid must be at stationary. Make sure that there are

no air bubbles in the tube.

Also allow sufficient time to adjust for a stable temperature profile.

The system is now ready for a measurement or custom calibration by adjusting the

calibration factor if needed (see chapter CUSTOM CALIBRATION PROCEDURE).

Zero adjustment is also necessary when re-clamping the sensor or changing to a different

sensor table, which adjusts for different calibration parameters, like medium, temperature

or tubing.

Zero adjustment cannot be performed when the coupling is below 50%.

8.7 Performing Flow Measurements

8.7.1 Measurement Using the Analog Interface of BioProTT™ Flow Meters

The flow meter can be connected to data acquisition or process control systems with the

analog interface. The flow meter has two analog interfaces for transmitting the Flow and

RSS (acoustic coupling) values. The values are transmitted within the range of

(0)4-20 mA.

8.7.1.1 Received Signal Strength (RSS / Acoustic Coupling) on Analog Interface

The software maps the RSS value from 0-100% linearly to 4-20 mA. The current output of

for RSS can be interpreted in the following way:

0 mA indicates a broken cable, circuit or power leakage

Currents in range of 0.2 to 0.5 mA indicate an error or invalid sensor or sensor not

yet recognized

4 mA equals 0 % coupling / received signal strength (or no signal)

20 mA equals 100% RSS (excellent signal)

The RSS value should be at least 50 % respectively 12.0 mA. This indicates a good signal

and will ensure accurate flow measurements.

If the tube is too small or the transducer is too large, or there is no liquid or bubbles inside

the tubing this can also explain why the coupling is insufficient. Make sure that the tube

fits the transducer you are using. Also follow the procedure described in chapter


INSTALLATION OF THE BIOPROTT™ CLAMP-ON TRANSDUCER when clamping

the sensor onto the tube.

8.7.1.2 Flow Value on Analog Interface

The analog interface consist of a (0)4-20 mA current loop. Make sure that the voltage

supply for the current loop is 24 V DC.

The current output of the device for flow can be interpreted in the following way:

0 mA indicates a power outage or a broken cable respectively broken circuit

0.2 to 0.5 mA indicate invalid flow conditions e.g. low coupling, or an error

condition like invalid sensor or sensor not yet recognized

1 mA to < 4 mA corresponds to negative flow, with 1 mA corresponding to the

negative flow value applying the same gradient as with the positive flow values. This

means the mapping of the negative flow into a current value is truncated at 1 mA.

The 1 mA value corresponds to a negative flow of 28% of the nominal flow range of

the calibration table.

4 mA equals zero flow, with offset correction properly (sensor offset zeroed)

20 mA corresponds to the 1.5 x maximum nominal flow Qmax of the selected table

of the connected sensor. See the table below for the calculation of the specific

conversion factors that must be applied.

> 20 mA to 23 mA indicate flow out of nominal and extended range

Figure 33 shows the flow rate versus the output current for a sensor with a standard flow

range of 10000 ml/min. The conversion of a flow to a current is scaled to the Qmax in the

sensor table.


Figure 33: Output Current versus Flow

To calculate an output current into the flow value (with adjusted calibration factor

accounted for), use the following equation:

Flow[ml/min]=(Current Output [mA]- 4 mA)*Analog Current Conversion Factor

The analog current conversion factor depends on Qmax of the selected sensor table. This

value is indicated in the calibration report, indicated as range on the display, or given on

the serial port. The Qmax related to analog current conversion factors are indicated in

Table 17.


To calculate an output current into the “original” flow value as the system is measuring it

(without adjusted calibration factor), use the following equation:

Reliability of flow values at distortions, e.g. bubbles

Note: As Ultrasound is reflected by gaseousness and solid particles the flow reading can be

inaccurate when there are bubbles present in the system. Bubbles can be detected by

observing the coupling value. This value is either fluctuating (small bubbles) or constantly

low during the passage of larger bubbles or foam. To avoid inaccurate readings the flow is

disabled at insufficient coupling values below 50% and is enabled when the coupling

reaches 50% again.

As the flow values are averaged values we recommend ignoring flow values for 1-2

seconds after coupling has increased beyond 50%. This is especially true for the 10 second

mean flow transmitted by the serial interface where it can take up to 10 seconds to average

out the effect. Since the flow measurement system has no insufficient coupling status

storage hold time and no measurement error ignore time, assessment and handling of the

flow values after recovery of a drop in RSS value must be performed by the user according

to his needs.

Considerations when only working with analog interfaces e.g. within a process control cabinet

If only the analog interfaces of the flow meters without display, i.e. either

BioProTT™ FlowTrack or BioProTT™ FlowTrack DINrail, are used to process data, only

the flow and RSS value are available. BioProTT™ FlowTrack DINrail provides in addition

a remote zero option, to zero flow with a 24V DC pulse.

There are no means to

Change the calibration factor on the device. The default factor applied is 1.00.

Select a different calibration table than the first one (default table).

Check the maximum flow Qmax of the sensor. Note: the analog interface is mapped

according to Qmax of selected sensor table.

Zero the flow value via an analog interface of BioProTT™ FlowTrack; zeroing

manually is possible.

The calibration factor at device level is usually of lesser importance as this can actually be

included in the conversion of the analog flow signal into a flow value.

Only the first calibration table of a sensor can be used in such a scenario. The Qmax of the

sensor must be taken into account when converting the analog flow reading.

Remote zeroing of BioProTT™ FlowTrack is not possible in this scenario with a direct

analog input signal. However, based on the specific mapping of flow values into current

values it is possible to correct the analog flow reading accordingly and have a correct

reading for the process control available. This is done by recording the flow reading (or

flow offset) when the user has confirmed the zero condition, i.e. tubing filled, sensor lid

closed and no movement in the tube. This flow offset is then subtracted from the flow

reading on the interface and results in the actual offset corrected flow reading, which the

flow meter would provide when the zero button is pressed. The flow offset can be used

until the next zeroing needs to take place, e.g. because a sensor is changed or a new

process is started.


8.7.2 Measurement Using the Digital Interface (RS232)

Via the asynchronous serial communication port the different BioProTT™ flow meters can

communicate with a host system.

The interface must be initialized to the following parameters:

Baud rate 38400 Baud

Bits 8 data bits

Start bit 1

Stop bit 1

Parity no

No hardware (CTS/RTS) or software (Xon/Xoff) handshake

The data transmission runs without any request from the host system.

The following commands are available via the digital interface. Every command has to be

sent with carriage return <CR>.

The recommended delay between 2 commands should be not less than 1 second.

Command Meaning Remark

8.7.3 Measurements Using BioProTT™ FlowTrack plus

BioProTT™ FlowTrack plus is equipped with a display and supports the following

functions via the graphical user interface (GUI). The screens shown are only examples of

actual possible screen contents.

When using the display and changing settings like calibration table or

calibration factor in parallel via the digital interface the change via the

digital interface will only be visible at the display when the specific screen

is “flashed” i.e. if the user changes to a different screen and back. The new

value will however take immediate effect on the measurements.

8.7.3.1 Flow Value and Coupling

Flow value and coupling are displayed as follows.

Screen Meaning

Flow value and coupling (RSS) are displayed as follows.

The flow value is calculated using the selected calibration table

and calibration factor.

When the flow value is greater than ±999 ml/min, the units

displayed are changed to [l/min].

In order to adjust the “zero” offset, please ensure that there is

sufficient coupling and no flow in the tubing and press the

“zero” button until the flow value is reset to zero.

The current RSS value is shown if a sensor is connected. If

coupling becomes insufficient (<50%), the flow value will be

blanked out. For details see Received Signal Strength (RSS /

Acoustic Coupling).

Table 20: Flow and coupling screen of BioProTT™ FlowTrack plus


8.7.3.2 Selection of Calibration Table

A Clamp-On Transducer can hold up to 7 calibration tables, which can be selected via the

appropriate screen, using the Arrow and Enter buttons.

Screen Meaning

The calibration table screen can be accessed only when a valid

sensor is connected.

The calibration table is an attribute connected to the sensor.

When the device is powered on/off and/or the sensor is changed

or reconnected the table is reset to table one (1).

Selecting a different calibration table does not change the

calibration factor.

When selecting a new table, “sel” appears on the screen. Please

confirm the new selection with the Enter button.

If the calibration table is changed, please zero the system at zero

flow for optimal measurement accuracy. Please also ensure that

the actual system setup and the calibration parameters shown in

the table are matching, otherwise inaccurate readings can occur.

The upper value of the range indicates the Qmax of the selected

table. Table 21: Calibration table screen of BioProTT™ FlowTrack plus


8.7.3.3 Selection of Calibration Factor

It is possible to adjust the calibration factor to accommodate e.g. a different medium or

temperature compared to the calibration settings of the connected Clamp-On Transducer.

The calibration factor can be adjusted in the following range: 0.50 to 1.50

Screen Meaning

The calibration factor screen can only be accessed when a valid

sensor is connected.

While on the calibration screen, the actual flow value is shown.

The default setting of the calibration factor is one (1.00).

The calibration factor is an attribute connected to the sensor.

When the device is powered on/off and/or the sensor is changed

or reconnected the factor is reset to one.

By pressing the Enter button and using the Arrow buttons the

factor can be changed in a range from 0.50 to 1.50 in 0.01 steps.

Pressing the Enter button again will store the value.

Changing the calibration factor will instantly affect the flow

value displayed on the screen and also on the analog and digital

output. Changes can be observed directly at the indicated flow,

below the factor.

In case of insufficient coupling the flow value is blanked out.

Table 22: Calibration factor screen of BioProTT™ FlowTrack plus

The calibration factor alters the flow by the following equation:

Flow value Calibration Factor = Calibration Factor * Flow value (Measured in sensor)

See chapter Custom Calibration Procedure for details.


8.7.3.4 Adjustment of Brightness

It is possible to adjust the display brightness as follows:

Screen Meaning

The default value is 50%. The value can be set to 25, 50, 75 and

100 %.

By pressing the Enter button the menu is activated by indicating

“sel” and the user can select the value by the Arrow Buttons.

Repeated pressing of the Enter button stores the selected value.

Table 23: Brightness screen of BioProTT™ FlowTrack plus

8.7.3.5 Totalizing

There is a built in flow totalizer available via the following screen.

Screen Meaning

The totalizer screen can be accessed only when a valid sensor

is connected. When entering the totalizing screen, initially zero

elapsed time and total flow value are shown.

After the totalizing has been engaged with the Enter button, the

totalizer indicates “Hold” and shows elapsed time and total

flow value in the units shown on the screen.

If the coupling is insufficient or a sensor table has been

selected an exclamation mark appears.

This indicates that the indicated totalized volume can differ

from real total flow due to changes in the liquid or the

calibration.

Table 24: Totalizing screen of BioProTT™ FlowTrack plus


The total flow is displayed in unit [ml] with three digits when the value is below one

liter (< 1 l). When the value is equal or higher than one liter the unit is changed to [l].

In this case the maximum displayed total flow is 999.9 liter whereas the digits for ml

shall be one. When the sum exceeds a value of 999.9 liters the lower left corner

shows 1 m³ and the totalizer will continue operating. The maximum digits for the m³

counter is 3 digits which corresponds to a maximum of 999 m³.

The totalizer has two limits. Either a totalizing time of 999:59:59 hours (approx. 6

weeks) or a totalized flow of 999 m³ 999.9 l. Whenever one of this limits is reached

the Totalizer is stopped and the string “OVR” (Overrun) is shown in the display. The

values for Totalizing Time and Total Flow are hold and shown on the display until

the user resets the totalizer, turns power off or disconnects the sensor.

When entering the totalizer screen the screen shows

o “Hold” when the totalizer is running and

o “Run” when the totalizer has not yet been started or stopped.

o By pressing the Enter Button the user is able to start/stop the totalizer.

Entering other menus of the device while the totalizer is running will not

have an effect on the totalizer.

When the totalizer is running and the Enter Button is pressed the totalizer is stopped.

The display will show the value for the total flow at this point and indicate “Run”

status.

Pressing the enter button again shall resume the totalizing progress starting with the

Totalizing Time and Total Flow before the stop. Additionally the Totalizing Time

value shall stop flashing.

While in the totalizer menu the totalizer is reset by pressing the Zero/Reset button.

The resetting can be performed while the totalizer is in the Hold or Run status. When

the totalizer is reset during run it continues working, starting with a zero value.

In case of insufficient low coupling (< 50%) during the run of the totalizer

an exclamation mark is shown next to the string “Total Flow” (Indication

for the user). During the time period of insufficient coupling the Totalizing

Time is stopped and the Total Flow value not changed (no further

summation).

If the coupling increases back to a “good” signal (value higher or equal to

50 %; e.g. after bubble has passed) the totalizing process resumes with the

values before the coupling drop. The exclamation mark shall stay on the

screen until the zero is pressed.

If a sensor is disconnected during the totalizer run the data are deleted.


8.7.3.6 Status and Error Information

The following information is displayed on the status and error screens.

Screen Meaning

When the system is starting up, the message “Initializing

Device” is displayed on the screen.

When accessing the status information screen, SW version and

serial number (SN) of the BioProTT™ flow meter are displayed.

When a sensor is connected and recognized its serial number

(CT) is displayed too.

When an error is detected, an error screen is shown with the

respective error code and message. An example is shown here.

Please refer to chapter AVAILABLE ERROR

CODES/INFORMATION FOR FLOW METER for detailed

error information. Note error information before turning the

device off.

This information is important for troubleshooting.

Table 25: Status and error screens of BioProTT™ FlowTrack plus

8.7.4 Custom Calibration Procedure

The BioProTT™ provides the possibility to do an on-site calibration adjustment to account

for different media, tubing wall thickness and temperatures. Strong differences in the

acoustic properties of the tubing and medium can lead to insufficient acoustic signal

strength (RSS) and affect the accuracy of the measurement.

The customization can be performed by sending the command “C” followed by the

calibration factor via the serial interface and confirmed with carriage return (see chapter

MEASUREMENT USING THE DIGITAL INTERFACE (RS232)). Additionally the

factor can be set via the display for the BioProTT FlowTrack plus (see chapter

SELECTION OF CALIBRATION FACTOR)


The calibration factor can be adjusted in a range from 0.50 to 1.50 in 0.01 steps with the

default value being 1.00. The internally derived flow value is multiplied with the factor.

The result is used to display the actual flow value on the different interface(s).

In order to do an on-site calibration adjustment you can set up a circulation loop and

compare the actual flow values with the values of a reference device. The reference device

can either be another flow meter or you can perform a timed collection of the flow.

Please note: the timed collection can also have a measurement error

depending on the collection time (measurement) and accuracy of the used

scale; generally the measurement error is diminished by a longer collection

time.

We recommend doing the custom calibration procedure for at least two different flow

rates, ideally in the typical flow range of your application.

With the first flow rate you compare the flow value with the reference device (or timed

collection) and adjust the calibration factor till both values match. With the second flow

rate you can check if both values still match in this range.

Please always ensure (as for any other measurements), that the system had enough time to

reach a stable temperature profile and that zeroing was done properly.

Please note: due to the different physical properties of liquids it cannot be

guaranteed that the calibration factor is valid for the complete flow range of

a sensor given in the datasheet. This can be checked with a reference device

or timed collection.

9.3 Troubleshooting

If you experience any problems with the flow measurement system, please try the

following solutions:

Problem Meaning / Solution

General

LED is not on

(only BioProTT™

FlowTrack and

BioProTT™

FlowTrack DINrail)

Power supply may be disconnected. Please check correct power

supply see chapter POWERING OF BIOPROTT™ Flow Meter

and disconnect Flow and RSS analog circuits.

If after correct power supply switching on and off leads to the

same behavior device needs to be serviced

Unexpected change

of RSS / acoustic

coupling value

One potential cause could be that calibration parameters do not

match the selected calibration table. Please check and adjust

accordingly.

Check also tubing for deformation, bubbles or debris.

“on”/”off” flow

reading (toggling

values)

A potential cause for a flow reading that toggles between an actual

value (“on”) and no value (“off”) can be disturbances in the flow

like small bubbles.

Please ensure that the medium is bubble free and apply acoustic

couplant. In case of a couplant used, check calibration conditions

and if necessary perform a custom calibration with check for

calibration factor.

Please also see chapter FLOW VALUE and handling of flow

distortions.

No Flow and RSS

reading

No sensor recognized; please check sensor connection incl. sensor

extension cable if deployed.

Note: flow sensors with higher flow rates are only supported on

flow meters with SW V3.0 and higher. Please check Qmax of

sensor tables, e.g. shown on calibration report.

Flow reading with

no flow present

Zero offset again and make sure that the liquid is NOT in motion

during zeroing.

Flow meter gets

application.


9.4 Checking Current Loops of Flow Meter

Current loops (Flow or RSS) can be tested with different measurement configurations

described in this chapter. Please make always sure that a Clamp-On Transducer is

connected and actual flow is occurring so that a reading is possible. The checks can be

performed similarly with the DIN rail variant of the flow meter, although not shown below.

Note: the flow meter needs to be powered properly.

Tolerances for current measurement (range of ampere meter 0-20 mA DC) are as follows:

Max 1 % + 5 digits at > 50.000 mA range

Internal resistance < 10 Ohm


9.4.3 Method 3 – Checking Functionality with Voltmeter

It is also possible to test the functionality of the current loops (Flow or RSS) with a

voltmeter. In this case, a resistor must be applied. Ohm’s law has to be observed to

calculate the correct current through the resistor. The loop can be powered either externally

or via flow meter as shown in the diagram below.

To avoid damages overvoltage protection of the voltmeter of at least 30 V DC is

recommend. The table indicates examples of conversion of 0-20 mA signal to

voltage.


Tolerances for voltage measurement (range of voltmeter 25 V DC or higher) are as

follows.

Resistor min 100 Ohm, max. 600 Ohm,

Tolerance of resistor min 1 % better 0,1 %

17.3 Output Strings of V2.4 versus V3.0

Due to extend of flow range the string can handle flows of 6 characters with prefix instead

of 5 characters plus prefix.

Version Output String Examples V2.4 (and

lower)

Positive flow: “00 00 100 1.00 -16653 -16655 -16694 +30” <CR><LF>

Negative flow: “00 00 100 1.00 16720 16712 16732 +31” <CR><LF>

V3.0 Negative flow: “00 00 100 1.00 -16109 -16121 -16122 +35” <CR><LF>

Positive flow: “00 00 100 1.00 16072 16061 16054 +34” <CR><LF>

Large negative flow: “00 00 100 1.00 -100107 -100111 -100122 +35” <CR><LF>

Large positive flow: “00 00 100 1.00 100205 100208 100205 +34” <CR><LF>

Due to the extended flow value, the output string starts at the same position but is two

characters longer.
