Compact transmitters for non-contactlevel measurement of fluids, pastes andcoarse bulk materials

ApplicationThe compact transmitters Prosonic M are used for continuous, non-contact level measurement in fluids and coarse bulk materials.Additionally the devices can be used for flow measurement in open channels and measuring weirs.

The following interfaces are available for system integration:• HART (standard), 4...20mA• PROFIBUS-PA• Foundation Fieldbus

The maximum measuring range is• FMU 40:

– 5m in fluids– 2m in bulk materials

• FMU 41:– 8m in fluids– 3.5m in bulk materials

• FMU 43:– 15m in fluids– 7m in bulk materials

Features and benefits• Simple, menu-guided on-site operation

with four-line plain text display• Envelope curves on the on-site display

for simple diagnosis• Easy operation, diagnosis and

measuring point documentation with the supplied ToF Tool operating program.

• Alignable IP 68 aluminium housing• optional remote display and operation• Installation possible from thread G 1½“

or 1½ NPT upwards• Integrated temperature sensor for time-

of-flight correction. Accurate measurements, even for temperature changes

• Linearisation function (up to 32 points) for measured value output in any unit of length, volume or flow rate

• Non-contact measurement method, therefore almost independent of product properties

Function and system design

Measuring principle

Time-of-flight methodThe sensor of the Prosonic M transmits ultrasonic pulses in the direction of the product surface. There, they are reflected back and received by the sensor. The Prosonic M measures the time t between pulse transmission and reception. The instrument uses the time t (and the velocity of sound c) to calculate the distance D between the sensor membrane and the product surface:

D = c ⋅ t/2

As the device knows the empty distance E from a user entry, it can calculate the level as follows:

L = E - D

An integrated temperature sensor compensates for changes in the velocity of sound caused by temperature changes.

Interference echo suppressionThe interference echo suppression feature on the Prosonic M ensures that interference echos (e.g. from edges, welded joints and installations) are not interpreted as a level echo.

CalibrationEnter the empty distance E and the span F to calibrate the device.

Blocking distanceSpan F may not extend into the blocking distance BD. Level echos from the blocking distance cannot be evaluated due to the transient characteristics of the sensor.

E: Empty distance; F: Span (full distance); D: Distance from sensor membrane - product surface; L: Level; BD: Blocking distance

Equipment architecture System integration via 4 ... 20mA output with HART protocol

The device can be operated on-site using either the display module VU 331 or the supplied ToF Tool program. The device can also be operated remotely using the HART handheld terminal DXR 275 or using the ToF Tool.If the HART communication resistor is not built into the power supply device, a 250 Ω communication resistor in the 2-wire line must be inserted.

System integration using PROFIBUS-PA

A maximum of 32 transmitters (8 if mounted in an explosion hazardous location EEx ia IIC according to FISCO-model) can be connected to the bus.The segment coupler provides the operating voltage to the bus. Both on-site as well as remote operation are possible.

System integration using Foundation Fieldbus (FF)

A maximum of 32 transmitters (standard or EEx d) can be connected to the bus. For protection class EEx ia: the maximum number of transmitters depends on the established rules and standards for intrinsically safe circuits (EN 60070-14) and proof of instrinsic safety. Both on-site and remote operation are possible.

System integration using Endress+Hauser Rackbus

You can interconnect a maximum of 64 devices with HART protocol to a Rackbus. Use an FXN 672 interface module for each device. You can integrate this bus into a higher-level bus by using a ZA gateway. Gateways are available for MODBUS, FIP, PROFIBUS, INTERBUS etc. Both on-site and remote operation are possible.

Input

Measured variable The distance D between the sensor membrane and the product surface is measured (page 2). Using the linearisation function, the device uses D to calculate:• level L in any units• volume V in any units• flow Q across measuring weirs or open channels in any units

Measuring range The measuring range is limited by the range of a sensor. The sensor range is, in turn, dependent on the operating conditions. To estimate the actual range, proceed as follows (see also the calculation example in the diagram):

1. Determine which of the influences shown in the following table are appropriate for your process.

2. Add the corresponding attenuation values.3. From the total attenuation, use the diagram to calculate the range.

Linearisation The linearisation function of the Prosonic M allows conversion of the measured value into any unit of length or volume. In open channels or measuring weirs, it is also possible to linearise the flow. Linearisation tables for calculating volume in horizontal cylindrical tanks are preprogrammed. You can also enter any number of other tables containing up to 32 value pairs either manually or semi-automatically (by filling the vessel under controlled conditions).You can use the supplied ToF Tool operating program to calculate the table automatically for any tank form and then enter it in the device.

Installation conditions for level measurements

• Do not install the sensor in the middle of the tank (3). We recommend leaving a distance between the sensor and the tank wall (1) measuring 1/6 of the tank diameter.

• Use a protective cover (page 25), in order to protect the device from direct sun or rain (2).• Avoid measurements through the filling curtain (4).• Make sure that equipment (5) such as limit switches, temperature sensors, etc. are not located

within the emitting angle α. In particular, symmetrical equipment (6) such as heating coils, baffles etc. can influence measurement.

• Align the sensor so that it is vertical to the product surface (7).• Never install two ultrasonic measuring devices in a tank, as the two signals may affect each

other.• To estimate the transmitted echo beam and its detection range, use the 3 dB emitting angle α

(see Fig.)

Installation conditions for flow measurements

• Install the Prosonic M at the inflow side, as close above the maximum water level Hmax as possible, plus the blocking distance BD.

• Position the Prosonic M in the middle of the channel or weir.• Align the sensor membrane parallel to the water surface.• Keep to the installation distance of the channel or weir.• You can enter the "Flow to Level" linearisation curve ("Q/h curve") using ToF Tool or manually via

the on-site display.

Blocking distance;nozzle installation

Install the Prosonic M at a height so that the blocking distance BD is not undershot, even at maximum fill level. Use a pipe nozzle if you cannot maintain the blocking distance in any other way. The interior of the nozzle must be smooth and may not contain any edges or welded joints. In particular, there should be no burr on the inside of the tank side nozzle end. Note the specified limits for nozzle diameter and length. To minimise disturbing factors, we recommend an angled socket edge (ideally 45°).

Caution!If the blocking distance is undershot, it may cause device malfunction.

Note!In order to prevent the level from entering the blocking distance, you can specify a safety distance (SD). If the level is within this safety distance, the Prosonic M outputs a warning or alarm message.
