Chapter Outline

This chapter introduces the measurement system used by this equipment, andthe organization and structure of the equipment.

1 - 2

1.1 Measurement System

A vortexor inserted into a flow alternately generates a regular vortex("Karman vortex") downstream. When specifying f for the Karman fre-quency, d for the width of the vortexor, and v for flow speed, the followingrelation is observable:

f = St V/d

As St represents a non-dimensional number called Strouhal, and is also a con-stant number, within the range of a certain Reynolds number, according to theshape of the vortexor, measuring frequency f tells us V, and V can tells us thevolume rate of flow.

As shown in Figure 1.1, this flowmeter is equipped with two pairs of ultra-sonic wave sensors, each consisting of a transmitter and a receiver, down-stream from the vortexor. The transmitter constantly sends ultrasonic wavesinto the liquid. These ultrasonic waves pass through the liquid, and reach thereceiver within a specific period of time. When a Karman vortex is generatedin the opposite direction from this transmission as shown in Figure 1.1, trans-mission time to the receiver is increased. On the other hand, when the direc-tion of the Karman vortex flow and the ultrasonic wave are the same, thetransmission time is decreased. The transmission time changes in proportionto the frequency of the vortex. The flow rate can therefore be measured byidentifying changes in the amount of time it takes an ultrasonic wave to reachthe receiver.

As the ultrasonic wave sensors are affixed outside the pipeline of theflowmeter main unit, measurement without touching the measured flow ispossible, and the sensor system is highly sensitive while remaining highlyresistant to the influence of vibration.

Chapter 2 Installation

2.1 Installation Location

To facilitate daily maintenance and operation, and to ensure accuracy evenduring extended use, take the following into consideration when selecting aninstallation site.

Caution• Measurement may not be possible in a two-phase flow consisting

of gas and liquid or a flow that contains bubbles. Take care not toget liquids containing air bubbles in flows.

• If bubbles are trapped in the flowmeter, accurate measurementmay not be possible. When installing the flowmeter, take care thatbubbles are not trapped in the flowmeter.

• Do not subject the flow meter directly to water or other fluids. Ifinstalling in locations subject to water, the wiring connectors mustbe sealed thoroughly with glands, and the transducer cover mustbe closed tightly.

1) The flowmeter may be installed at any angle; always confirm, however,that the pipe is completely filled with liquid.Avoid installing the Transducer unit below the water surface, to protectagainst power shortage. Liquid builds up around the flowmeter duringoperation.

2) When installing on vertical pipe, make the piping in such a way thatensures that measured liquid flows from bottom to top when the pipe isfilled with liquid.

3) Avoid any location subject to extreme fluctuations in temperature.4) Although the flowmeter possesses a good aseismatic structure, to maxi-

mize protection of the piping and joints, keep vibration and shocks un-der 9.8 m/s2 by using supports.

5) As the main unit is made of a stainless and aluminum alloy, avoid expo-sure to corrosive environments.

6) As the water-resistant structure of this flowmeter is comparable to theJIS C0920 water-resistant structure (IEC IP66), it is not intended forsubmerged use.

7) Install at a location with sufficient clearance to conduct inspections.8) Install at a location with sufficient clearance to enable installation of

wiring and piping.

2.2 Notes on Installing the Piping the Equipment

To ensure accuracy even during extended use, take the following into consid-eration when installing the piping and equipment.

80A to 100A Comparable to schedule 80 Schedule 80 or greater

4) To ensure flow-rate measurement accuracy, make sure the gaskets be-tween the flowmeter and the connection pipe remain outside the flowroute.

5) In the event that a pressure tap is required, to ensure the flow-rate mea-surement accuracy, install the tap at a distance, as measured from theedge of the downstream side of the flowmeter toward the lower stream,equal to at least twice the outlet diameter the diameter of the flowmeter.In the event that a temperature tap is required, install the tap at a dis-tance from the pressure tap toward the lower stream equal to at leastthree times the outlet diameter the diameter.

6) When making piping, ensure that the flowmeter and connection pipe arecoaxial. Any gaps in the coaxial (gap in the center) will causeunstability and instrument errors. Use the center-aligning metal fittingsand carry this out referring to page 2-11 included with the flowmeter,for installation.

7) Large ripples, such as those caused by a bellows pump, may create vari-ance. Use a damper to minimize such ripples.

8) With lines which have globe valves and in which drift currents or rotat-ing flows may occur, the flow meter should be positioned upstream ofthe valves.

(Continued on the next page)

1) Match the flow direction of the fluid to the direction indicated ( u mark)on the flowmeter.

2) To ensure flow-rate measurement accuracy, install straight pipes of alength described in Table 2.1 on upstream and downstream sides of theflowmeter.

9) When installing a heat converter that significantly modifies liquid tem-perature, install it downstream of the flowmeter. In the event that itmust be installed upstream, do so at an appropriate distance from theflowmeter.

10) Cavitation lowers flow-rate measurement accuracy. To prevent cavita-tion, maintain the minimum pressure at the downstream line (located ata distance of 2-7 times the diameter of the flowmeter) at a pressuregreater than or equal to the result of the formula shown below.

Pd = 2.7 Í ∆P + 1.3 Í P0

Pd : Downstream pressure (kPa, absolute pressure)∆P: Pressure loss (kPa)P0 : Vapor pressure of fluid at the temperature during measure-

ment (kPa, absolute pressure)

The following formula calculates pressure loss.∆P = c Í γ

∆P: Pressure loss (kPa)c : Pressure-loss coefficient (according to Figure 2.1)γ : Fluid density (kg/m3)

Caution • Ensure that the internal diameter of the connection pipe is equal to

or greater than that of the flowmeter. • Install gaskets between the flowmeter and the connection pipe and

ensure that they are installed outside the flow route; otherwise, aninstrument error will occur.This will cause errors.

• Pipe vibration should be minimized. The vibration frequency cannotbe matched, and errors may occur.

• To prevent cavitation, allow sufficient back-pressure (pressuredownstream of the flowmeter).

2.5 Changing the Direction of the Converter / Indicator

When installation location of the flowmeter necessitates changing the direc-tion of the converter and/or indicator, perform the following procedures.

The flowmeter must be connected to piping or placed on a stable work table.

2.5.1 Changing the Direction of the Converter Case

To turn the converter case through 180˚ in relation to the flow direction, per-form the following procedure:

1) If power is being supplied to the flowmeter, turn off the power.2) Remove the four bolts (5-inch) at the bottom of the converter.3) Lift the converter 2 to3 mm, and turn it through 180˚.

The ultrasonic-wave sensor cable (thin electric wire) resides betweenthe flowmeter main unit and the converter case, and connects them.When rotating the converter, be careful not to sever the cable. Do notrepeatedly turn the converter 180˚ in the same direction. Turn the casein the opposite direction every rotation to prevent the internal cablefrom being twisted and possibly severed.

4) After setting the direction of the converter, place the converter on theflowmeter main unit, and completely tighten the four bolts (5-inch) atthe bottom of the converter completely.Since the JIS pressure-resistance explosion-proof model of the flowme-ter has a pressure-resistant, explosion-proof structure, completelytighten the bolts.

• Since the flowmeter has a pressure-resistant explosion-proof struc-ture, completely tighten the four bolts (5-inch) at the bottom of theconverter after changing the direction of the converter, to maintainthe explosion-proof structure.

• If the explosion-proof structure is not maintained due to insufficienttightening of the bolts, a fire or explosion may occur when the flow-meter is used in hazardous operating conditions.

Warning

• When changing the converter direction, be careful not to sever theultrasonic wave sensor cable running between the flowmeter mainunit. Turn the converter in the opposite direction every rotation toprevent the internal cable from being twisted and possibly severed.

2.5.2 Changing the Direction of the Indicator (Optional)

To turn the direction of the indicator 90˚ as shown in Figure 2.11, perform thefollowing procedure.

1) If power is being supplied to the flowmeter, turn off the power.2) Remove the converter lid after loosening the set screws (with which it is

affixed), as shown in Figure 2.12.After loosening the set screws, turn the converter lid to remove it. Notethat there is an O-ring in the connection area.

3) Remove the LCD.Remove the two screws affixing the LCD, and remove the LCD to-gether with the outer-facade panels.

4) Change the direction of the indicator.After changing the direction of the indicator, insert the connector at thebottom of the board into the LCD receptacle.

5) Fix the LCD into place.Affix the LCD with the two screws (removed in Step (3) above).

6) Attach the converter lid to the converter main unit. Remember to cor-rectly position O-ring.

7) After completely tightening the converter lid, tighten the set screws forthe turn stopper.

• Since the flowmeter has a pressure-resistant explosion-proof struc-ture, completely tighten the converter lid after changing the directionof the indicator, to maintain the explosion-proof structure.

• If the explosion-proof structure is not maintained due to a failure totighten the converter lid, a fire or explosion may occur when theflowmeter is used in dangerous operating conditions.

2) Analog outputThe analog transmission loop of this flowmeter is created by establish-ing load resistance between the + line and - line of the analog outputline. (The analog output line is also used as a power supply line for theflowmeter.)

3) Pulse output / Alarm outputThe pulse output/alarm output of this flowmeter is an open collectoroutput. Connect a power source, using the current limit resistance, be-tween the pulse/alarm output line and COM line to be used. Ensure thevalue of current limit resistance does not exceed the capacity of thepulse output.

4) Remove the terminal cover at the amp case and the dust-proof plug atthe wiring connection before attempting to install the wiring.

5) To assure water-resistance, conduit tubes and ducts should be used forexternal wiring.

3.2 Wiring Precautions

• The specified pressure-resistant seal fittings must be used at thecable inlets when using in hazardous atmospheres.

• Failure to use the specified pressure-resistant seal fittings, or use ofunspecified fittings will not guarantee the explosion-proof construc-tion, and there will be a danger of explosion in some cases.

Warning

1) The cables used should be as follows.Recommended cable: CVV-S or CEV-S

Flow meter output Cores

None, or analog output only 2-core shielded

None, or analog output only 2-core shielded x2

+

pulse output or alarm output

Pulse or alarm output only 3-core shielded

* Ensure that the total of the circuit resistance and load resistancematches the value in figure 2.2.

* It is recommended that cables are used with cross-sectional areas of atleast 1.25mm2.

* It is recommended that CEV-S cable with a cross-sectional area of atleast 2mm2 is used if the transmission distance exceeds 500m.

2) In order to prevent noise intruding, the cables should be kept away fromnoise sources such as large-capacity motors, transformers and powerplants, or from high-voltage and high-current sources.

3) If using explosion-proof specifications, the pressure-resistant seal fit-tings included (or as optional specifications) must be used.

5.3.1 Summary of Print Functions

5.3 Printing Out Data

In order to perform flow rate measurements correctly, it is important to checkthe internal settings and responses from the Vortexor when starting operationand while running. It is therefore useful to communicate with an S-SFC fittedwith a printer, and print out the data. S-SFCs fitted with printers have twotypes of print functions, as defined below.

Introduction

Configuration print (data print):The S-SFC printer can be used to print out internal data from the Vortexor,such as tag number, damping time constant, and low flow cutoff. This printfunction is called "Configuration print" or "Data print".

Action print (data print):There is also a function for printing out continuously the response results fromthe Vortexor to the S-SFC key operations. This print function is called "Ac-tion print" or "Continuous print".

Definitions

The printer fitted to the S-SFC as an option is a 24 character/line thermalprinter. On switching on the S-SFC power, the printer automatically movesout and back before stopping. The printer paper is fed out slightly (approxi-mately 5mm) here.

Printer

To feed the printer paper, press "SHIFT" + "8"."PRINTER FEED" is displayed on the screen, and the printer paper is fed outby one line. Pressing "8" while this is still displayed feeds out by another oneline.To cancel the feed function, press the "CLR" key to clear the "PRINTERFEED" display.

· Is the load resistance cor-

rect?

· Are there any external noise

sources e.g., motor line,

electromagnetic wave gen-

erator?

· Is there an element that is

disturbing the flow (e.g., a

valve that is upstream and

the closest to the flowme-

ter)?

· Is cavitation occurring?

· Are there bubbles in the liq-

uid?

· Is an object caught in the

vortexor?

· Is sensor fault alarm given?

· Adjust the power-supply so


range.

· Adjust the load resistance so


range.

· Isolate the flowmeter from

noise sources.

· Use a shield line.

· Change the installation site

of the flowmeter. (Confirm

that the specified length of

straight pipe is sufficient.)

· Confirm there is sufficient

line pressure to prevent

cavitation.

· Prevent the occurrence of

bubbles.

· Remove the object.

· If so, replace sensor.

6.2 Error Messages and Corrective Action

This section describes the error messages given by the SFC self-diagnosticfunction, and includes methods for corrective action.

Introduction

Error messages Details of status displays are described below.

R-1 SENSOR FAULTThe reception level of the receiving ultrasound sensor 1 (upper left and lowerright sensors viewed from upstream side of flow meter) has dropped. Checkthat the flow meter interior is full of water. If full of water, a sensor or receivercircuit fault is likely. If full of water and an alarm is given, the sensors must bereplaced.

R-2 SENSOR FAULTThe reception level of the receivingultrasound sensor 2 (upper right andlower left sensors viewed from up-stream side of flow meter) hasdropped. Check that the flow meterinterior is full of water. If full ofwater, a sensor or receiver circuitfault is likely, and the sensors mustbe replaced.

BAD CONFIG DATAThere is an error in the span or pulseoutput unit settings. Reconfigure atthe CONFIG (special function)menu.

EEPROM FAULTThe EEPROM is faulty. Reset the flow meter. (Hold a magnet close for atleast 3 seconds while pressing " p " and ENT buttons.)

S SENSOR FAULTThe sensor transmission circuit is faulty. The sensor must be replaced.

R12 SENSOR FAULTThe reception levels of both receiving sensors 1 and 2 have dropped. Checkthat the flow meter interior is full of water. If full of water, a sensor or receivercircuit fault is likely, and the sensors must be replaced.

FIXED PULSE MODETest pulse is currently being output.

IN OUTPUT MODEAnalog 4-20mA is currently being test output.

6.3 Sensor Replacement Instructions

This section describes the procedure for replacing sensors when sensor faultsoccur.

Introduction

Caution• The sensor capillary lengths vary depending on the opening diam-

eter. The correct replacement part must be used to match the rel-evant diameter.

Replacementprecautions Warning

• Before replacing sensors, check that the detector unit is not hot orcold. There is a danger of injury or burns.

Caution• The output signal disappears while sensors are being replaced.

Precautions must be taken such as operating manually to preventeffects on the control loop.

1. Switch off the power.2. Unscrew the set screw.3. Remove the transducer case cover while rotating.

Note that there is an O-ring in the joint section.4. Unscrew the retaining screws (M3x4) on amplifier unit, and pull out the

amplifier unit.The retaining screws are designed not to fall out, so do not pull out withexcessive force.

5. Detach the cable and power cable connectors attached to the amplifierunit.The sensor cable is fine wire, so take care not pull out with excessiveforce.

Replacementprocedure (continued)

6. Remove the bolts (M5x4) from the bottom of the transducer case.

7. Remove the bolts (M4x2, 4 locations) securing the sensor unit holderfrom the housing.

8. Remove the bolts (M8x2) securing the sensor unit to the housing.

9. Remove the sensor unit from the housing.

10. Wash the replacement sensor unit and housing holder attachment surfacewith organic solvent.Take care not to scratch the holder underside and attachment surface, orleave debris adhering when washing.

11. Fit the seal to the replacement sensor unit holder.

12. Thinly apply silicone adhesive to the underside of the holder.Take care that air bubbles are not introduced here.

13. Thread the tube between the housing ribs, and attach the sensor unit to thehousing.If the tube does not align with the groove and the holder rises above at-tachment surface, arrange the tube first before continuing. (The replace-ment sensor unit tube is made to match the housing profile. If the profiledoes not match, however, it should be repaired.)After attaching, seal the holder underside to the attachment face by push-ing the holder firmly against the attachment face to eliminate air bubblesfrom between the holder underside and attachment face.

14. Tighten the flat spring and retaining plate with the bolts (M4x2).(Tightening torque: 12 - 18kgf.cm)

15. Refit the transducer case, amplifier unit, and transducer case cover in thereverse order in which they were removed.Take care not to forget to fit O-rings, connect connectors, or tighten re-taining screws, etc.
