Chapter 3 Measurements site selection


Chapter 3 Measurement site selection

When selecting a measurement site, it is important to select an area where thefluid flow profile is fully developed to guarantee a highly accurate measurement.Use the following guidelines to select a proper installation site: Choose a sectionof pipe that is always full of liquid, such as a vertical pipe with flow in the upwarddirection or a full horizontal pipe. Ensure enough straight pipe length at least equalto the figure shown below for the upstream and downstream transducersinstallation. Select a fluid-filled section, such as a vertical section of the line (upward flow

is preferred) or a horizontal section filled with fluid. The measuring point should be within 10 diameters (10D) of the upstream

and 5 diameters (5D) of the downstream, without any devices such as valves,elbows and diameters interfering with the flow field.The length of straight pipeis recommended as shown in FIG. 6.

On the horizontal pipe section, the sensor should be installed at 9 o 'clockand 3 o 'clock of the pipe and should avoid the position at 6 o 'clock and 12 o'clock, so as to avoid the attenuation of the signal caused by the sediment atthe bottom of the pipe or the bubbles and cavitation at the top of the pipe.

Make sure the temperature at the measuring point is within the working range. Full consideration should be given to the condition of scale formation on the

inner wall of the pipe, and the tube section without scale should be selectedfor measurement as far as possible. If it cannot be completely satisfied, thescale formation should be considered as the lining in order to obtain bettermeasurement accuracy.

Select the tube segment with uniform density and easy ultrasonictransmission.

Ensure that the pipe surface temperature at the measuring point is within thetransducer temperature limits. Consider the inside condition of the pipe carefully. Ifpossible, select a section of pipe where the inside is free of excessive corrosion orscaling.

Chapter 3 Measurement site selection


Chapter 4 Transducer installation


Chapter 4 Transducer installation4.1. Installing the transducers

Before installing the transducers, clean the pipe surface where the transducers areto be mounted. Remove any rust, scale or loose paint and make a smooth surface.Choose a section of sound conducting pipe for installing the transducers. Apply awide band of sonic coupling compound down the center of the face of eachtransducer as well as on the pipe surface, ensure there are no air bubblesbetween the transducers and the pipe wall, and then attach the transducers to thepipe with the straps provided and tighten them securely.

Note:1. The two transducers should be mounted at the pipe’s centerline on horizontalpipes. Make sure that the transducer mounting direction is parallel with the flow.

2. During the installation, there should be no air bubbles or particles between thetransducer and the pipe wall. On horizontal pipes, the transducers should bemounted in the 3 o’clock and 9 o’clock positions of the pipe section in order toavoid any air bubbles inside the top portion of the pipe. (Refer to TransducerMounting).

3. If the transducers cannot be mounted horizontally symmetrically due tolimitation of the local installation conditions, it may be necessary to mount thetransducers at a location where there is a guaranteed full pipe condition (thepipe is always full of liquid).

4.1.1. Transducer spacingAfter entering the required parameters, the spacing between the ENDS of the twotransducers is considered as the standard transducer spacing (Refer to Top Viewon transducer mounting methods). Check the data displayed in Window M25 andspace the transducers accordingly.

4.1.2. Transducer mounting methodsThree transducer mounting methods are available. They are respectively: V



method, Z method and N method. The V method is primarily used on smalldiameter pipes (DN100~300mm, 4〞 ~12〞 ). The Z method is used in

applications where the V method cannot work due to poor signal or no signaldetected. In addition, the Z method generally works better on larger diameterpipes (over DN300mm, 12〞) or cast iron pipes.

The N method is an uncommonly used method. It is used on smaller diameterpipes (below DN50mm, 2〞).

4.1.3. V methodThe V method is considered as the standard method. It usually gives a moreaccurate reading and is used on pipe diameters ranging from 25mm to 400mm(1＂~16〞 ) approximately. Also, it is convenient to use, but still requires proper

installation of the transducers, contact on the pipe at the pipe’s centerline andequal spacing on either side of the centerline.

4.1.4. Z methodThe signal transmitted in a Z method installation has less attenuation than a signaltransmitted with the V method when the pipes are too large, there are somesuspended solid in the fluid, or the scaling and liner are too thick .This is becausethe Z method utilizes a directly transmitted (rather than reflected) signal whichtransverses the liquid only once.The Z method is able to measure on pipe diameters ranging from 100mm to800mm (4〞~32〞) approximately. Therefore, we recommend the Z method forpipe diameters over 300mm (12〞).



4.1.5. N methodWith the N method, the sound waves traverse the fluid three times and bouncetwice off the pipe walls. It is suitable for small pipe diameter measurement.The measurement accuracy can be improved by extending the transit distancewith the N method (uncommonly used).

4.2. Transducer mounting inspectionCheck to see if the transducer is installed properly and if there is an accurate andstrong enough ultrasonic signal to ensure proper operation and high reliability ofthe transducer. It can be confirmed by checking the detected signal strength, totaltransit time, delta time as well as transit time ratio.The "mounting" condition directly influences the flow value accuracy and systemlong-time running reliability. In most instances, only apply a wide band of soniccoupling compound lengthwise on the face of the transducer and stick it to theoutside pipe wall to get good measurement results. However, the followinginspections still need to be carried out in order to ensure the high reliability of themeasurement and long-term operation of the instrument.



4.2.1. Signal strengthSignal strength (displayed in Window M90) indicates a detected strength of thesignal both from upstream and downstream directions. The relevant signalstrength is indicated by numbers from 00.0~99.9. 00.0 represents no signaldetected while 99.9 represents maximum signal strength.

Normally, the stronger the signal strength detected, the longer the operation of theinstrument reliably, as well as the more stable the measurement value obtained.Adjust the transducer to the best position and check to ensure that enough soniccoupling compound is applied adequately during installation in order to obtain themaximum signal strength.

System normally requires signal strength over 60.0, which is detected from bothupstream and downstream directions. If the signal strength detected is too low, thetransducer installation position and the transducer mounting spacing should be re-adjusted and the pipe should be re-inspected. If necessary, change the mountingmethod to be Z method.

4.2.2. Signal quality (Q value)Q value is short for Signal Quality (displayed in Window M90). It indicates the levelof the signal detected. Q value is indicated by numbers from 00~99. 00 representsthe minimum signal detected while 99 represent the maximum.Normally, the transducer position should be adjusted repeatedly and couplingcompound application should be checked frequently until the signal qualitydetected is as strong as possible.

4.2.3. Total time and delta time"Total Time and Delta Time", which displays in Window M93, indicates thecondition of the installation. The measurement calculations in the flowmeter arebased upon these two parameters. Therefore, when "Delta Time" fluctuates widely,the flow and velocities fluctuate accordingly, this means that the signal qualitydetected is too poor. It may be the resulted of poor pipe-installation conditions,



inadequate transducer installation or incorrect parameter input.Generally, "Delta Time" fluctuation should be less than ±20%. Only when the pipediameter is too small or velocity is too low can the fluctuation be wider.

4.2.4. Transit time ratioTransit Time Ratio indicates if the transducer mounting spacing is accurate. Thenormal transit time ratio should be 100+/-3 if the installation is proper. Check it inWindow M91.

4.2.5. Warnings(1) Pipe parameters entered must be accurate; otherwise the flowmeter will not

work properly.(2) During the installation, apply enough coupling compounds in order to stick the

transducers onto the pipe wall. While checking the signal strength and Qvalue, move the transducers slowly around the mounting site until thestrongest signal and maximum Q value can be obtained. Make sure that thelarger the pipe diameter, the more the transducers should be moved.

(3) Check to be sure the mounting spacing is accordance with the display inWindow M25 and the transducer is mounted at the pipe’s centerline on thesame diameter.

(4) Pay special attention to those pipes that formed by steel rolls (pipe withseams), since such pipe is always irregular. If the signal strength is alwaysdisplayed as 0.00, that means there is no signal detected. Thus, it isnecessary to check that the parameters (including all the pipe parameters)have been entered accurately. Check to be sure the transducer mounting

AttentionIf the transit time ratio is over 100±3,it is necessary to check:(1) If the parameters(pipe outside diameter,wall thickness,pipe material,line, etc.) have been

entered correctly,(2) If the transducer mounting spacing is accordance with the display in Windows M25,(3) If the transducer is mounted at the pipe’s centerline on the same diameter,(4) If the scale is too thick or the pipe mounting is distorted in shape, etc.

Chapter 5 Operating instructions


(5) method has been selected properly, the pipe is not worn-out, and the liner isnot too thick. Make sure there is indeed fluid in the pipe or the transducer isnot too close to a valve or elbow, and there are not too many air bubbles inthe fluid, etc. With the exception of these reasons, if there is still no signaldetected, the measurement site has to be changed.

(6) Make sure that the flowmeter is able to run properly with high reliability. Thestronger the signal strength displayed, the higher the Q value reached. Thelonger the flowmeter runs accurately, the higher the reliability of the flow ratesdisplayed. If there is interference from ambient electromagnetic waves or thesignal detected is too poor, the flow value displayed is not reliable;consequently, the capability for reliable operation is reduced.

(7) After the installation is complete, power on the instrument and check theresult accordingly.

Chapter 5 Operating instructions5.1. System normal indentification

Press the keys. If the letter "*R" displays on the screen, itindicates system normal.If the letter "G" is displayed, it indicates that system is adjusting the signal gainprior to the measurement. Also, it means system normal. Only when theadjustment takes too long without stopping, can system be identified as abnormal.Letter "I" indicates no signal is being detected. Check the transducer wiringconnections are correct, the transducers are installed firmly, etc.

5.2. Zero set calibration

Once zero flow occurs, a zero point may indicate on each measuring instrument,but the displayed measuring value is not equal to "0", this value indicates "Zero".To any measuring instrument, the smaller the "Zero" is, the better the quality is.Conversely, if the Zero is too big, that indicates the quality of the instrument ispoor.If the zero set point is not at true zero flow, a measurement difference may occur.The smaller the physical measurement capacity is, the larger the measurement



difference from the zero point will exist. Only when zero point reduced to a definitedegree, as compared with the physical measurement capacity, can the measuringdifference from zero point be ignored.For an ultrasonic flowmeter, the measurement difference from zero point cannotbe ignored at low flow. It is necessary to perform a static zero set calibration toimprove low flow measurement accuracy.Press Window M42 to set the Zero, press first, and then wait the readingsdisplayed at the lower right corner reducing to be "0". If this is carried out with flow,the flow will be displayed as "0", M43 can help to restore settings.

5.3. Scale factor

Scale factor refers to the ratio between "actual value" and "reading value". Forexample, when the measurement and is 2.00, and it is indicated as 1.98 on theinstrument, the scale factor reading is 2/1.98. This means that the best scalefactor constant is 1.However, it is difficult to keep the scale factor as "1" on the instrument especiallyin batch productions. The difference is called "consistency".During operation, there still exists possible difference in pipe parameters, etc. The"scale factor" may be necessary when used on different pipes. Thus, scale factorcalibration is specially designed for calibrating the differences that result fromapplication on different pipes. The scale factor entered must be one that resultsfrom actual calibration. The scale factor can be input in Window M45.

5.4. System lock

System lock is readable but not modifiable to prevent operation error due tounauthorized tampering by unauthorized personnel.

Press the keys, if displays "Unlock" on the screen, then

press the key, enter 6 numerically long password, and then press the Enterkey to confirm.

Unlock it by using the selected password only. Press , if "lock" is

displayed on the screen, then press the key and enter the correct password,

then press Enter to confirm.Keep the password in mind or recorded in a safe place, otherwise the instrumentcannot be used.

5.5. Frequency output

The flowmeter is provided with a frequency output transmitter function. The high orlow frequency output displayed indicates the high or low flow rate reading. Theuser can reset the frequency output as well as flow rate as his requirements.For example: if a pipe flow range is 0~3000m3/h, the relative frequency outputrequired is 0~5000Hz, and the configuration is as follows:In Window M68 (low limit frequency output flow value), input 0;In Window M69 (high limit frequency output flow value), input 3000; Typical OCTOutput wiring diagram as below:

5.6. 4~20mA current loop output verification (optional)

Processing a current loop output exceeding an accuracy of 0.1%, the flowmeter isprogrammable and configurable with multiple output modes such as flow rate orfluid velocity. Select in Window M55. For details, please refer to "Windows DisplayExplanations".In Window M56, enter a 4mA flow rate or fluid velocity value. Enter the 20mA flowrate or fluid velocity value in Window M57. For example, if the flow range in a



specific pipe is 0~1000m3/h, enter 0 in Window M56 and 1000 in Window M57.Calibrating and testing the current loop is performed in Window M58. Completethe steps as follows:

Press , move or to display "0mA", "4mA","8mA", "12mA","16mA", "20mA" readings, connect an ammeter to test the currentloop output and calculate the difference. Calibrate it if the difference is withintolerance. If the difference is without tolerance, refer to the "Analog OutputCalibration" to calibrate the current loop.Check the present current loop output in Window M59 as it changes along withchange in flow.5.7. Recover the factory default

Press keys to Window m37, press or key tochoose “Reset” keys to recover the factory default.

5.8. 4~20mA analog output calibration

The hardware detect window must be activated prior to calibration the AnalogOutput. The procedure is as follows:

Press enter password "115800", then press Enter toactivate the detect menu. With no effect to next power on, this window will closeautomatically as soon as the power is turned off.

Press to calibrate the current loop 4mA output. Use an ammeter tomeasure the current loop output current.

At the same time, press or to adjust the displayed numbers. Watchthe ammeter until it reads 4.00. Stop at this point, the 4mA has been calibrated.

Then, press to calibrate the current loop 20mA output. The method is thesame as 4mA calibration. The results are automatically saved in EEPROM andwon’t lose when power off.

NoteEach flowmeter has been calibrated strictly before leaving factory. It is unneccessary to carrythrough this step except when the current value (detected while calibrating the current loop)displayed in Window M58 is not identical with the actual output current value.

7.2. FAQ

Question: New pipe, high quality material, and all installation requirements met:why still no signal detected?

Answer: Check pipe parameter settings, installation method and wiringconnections. Confirm if the coupling compound is applied adequately, thepipe is full of liquid, transducer spacing agrees with the screen readingsand the transducers are installed in the right direction.

Question: Old pipe with heavy scale inside, no signal or poor signal detected: howcan it be resolved?

Answer: Check if the pipe is full of fluid.Try the Z method for transducer installation (If the pipe is too close to awall, or it is necessary to install the transducers on a vertical or inclinedpipe with flow upwards instead of on a horizontal pipe).Carefully select agood pipe section and fully clean it, apply a wide band of couplingcompound on each transducer face (bottom) and install the transducerproperly.Slowly and slightly move each transducer with respect to eachother around the installation point until the maximum signal is detected.Be careful that the new installation location is free of scale inside the pipeand that the pipe is concentric (not distorted) so that the sound waves donot bounce outside of the proposed area. For pipe with thick scale insideor outside, try to clean the scale off, if it is accessible from the inside.(Note: Sometimes this method might not work and sound wavetransmission is not possible because of the a layer of scale between thetransducers and pipe inside wall).

Question: Why is the flow rate still displayed as zero while there is fluid obviouslyinside the pipe and a symbol of "R" displayed on the screen?

Answer: Check to see if "Set Zero" was carried out with fluid flowing inside thepipe(Refer to Window M42). If it is confirmed, recover the factory defaultin Window M43.

Chapter 9 Appendix-Serial interface network use and communications protocol


Chapter 9 Appendix-Serial interface network use andcommunications protocol

9.1. Overview

The transmitter has perfect communication protocol. It can also be connected to aRS-485. Two basic schemes can be chosen for networking, i.e. the analog currentoutput method only using the flowmeter or the RS485 communication method viaserial port directly using the flowmeter. The former is suitable to replace datedinstruments in old monitoring networks. The later is used in new monitoringnetwork systems. It has advantages such as low hardware investment and reliablesystem operation.

When the serial port communication method is directly used to implement amonitoring network system, the address identification code (in window M46) of theflowmeter is used as network address code. Expanded command set with [W] isused as communication protocol. Thus analog current loop and OCT output offlowmeter can be used to control the opening of a control valve. The relay outputcan be used to power-on/off other equipment. The analog input of the system canbe used to input signals such as pressure and temperature. The system providesan RTU function for flow measurement.

RS-485(0~1000m) can be directly used for data transmission link for a shortdistance. The command answer mode is used in data transmission, i.e. the hostdevice issues commands and the flowmeter answers correspondingly.

9.3. Communication protocol and the use

The communication protocol format used by the ultrasonic flowmeter is anexpanded set of the Fuji FLV series flowmeter protocol. The host device requeststhe flowmeter to answer by sending a "command". The baud rate of asynchronouscommunication (Primary station; computer system; ultrasonic flowmeter isgenerally 9600BPS. A single byte data format (10 bits): one start bit, one stop bitand 8 data bits. Check bit: NONE.

9.3.1. FUJI protocolThe communication protocol format used by the ultrasonic flowmeter is anexpanded set of the Fuji FLV series flowmeter protocol. The host device requeststhe flowmeter to answer by sending a "command". The baud rate of asynchronouscommunication (Primary station: computer system; Secondary station: ultrasonicflowmeter) is generally 9600BPS. A single byte data format (10 bits): one start bit,one stop bit and 8 data bits. Check bit: NONE.A data character string is used to express basic commands and a carriage return



(ENTER) is used to express the end of a command. The characteristic is that thestring of data is flexible. Frequently used commands are as follows:

Communications commandsNote:1. (cr)expresses carriage return. Its ASCII value is 0DH. (lf) expresses line feed.

Its ASCII value is 0AH.2. "d" expresses 0-9 number. 0 value is expressed as +0.000000E+00.

"d" expresses 0-9 numbers. There is no decimal point in integral part before"E".3. The status of the machine is expressed by 1-6 letters. See the error code

section for the meaning of the characters. For example, "R" and "IH".4. Eight "dddddddd" expresses the electronic serial number of the machine. "t"

expresses the type of machine.5. If there are multiple flowmeters in a data network then the basic commands

cannot be used alone. The prefix W must be added. Otherwise, multipleflowmeters will answer simultaneously, which will cause chaos in the system.

Function prefix and function signPrefix P

The character P can be added before every basic command. It meansthat the transferred data has CRC verification. The method of countingthe verified sum is achieved by binary system addition.For example: Command DI+(CR) (the relative binary system data is 44H,49H, 2BH, 0DH) transferred data is +1234567E+0m3. (CR) (the relativebinary system data is 2BH, 31H, 32H, 33H, 34H, 35H, 36H, 37H, 45H,2BH, 30H, 6DH, 33H, 20H, 0DH, 0AH). And command PDI+ (CR)



transferred data is+1234567E+0m3! F7 (CR), "!" means the character before it is the sumcharacter, and the verified sum of the two bytes after it is(2BH+31H+32H+33H+34H+35H+36H+37H+45H+2BH+30H+6DH+33H+20H=(2)F7H)Note: there can be no data before "!", and also may be a blank character.

Prefix WUsage of prefix W: W+ numeric string address code +basic command.Value range of the numeric string is 0~65535, except 13 (0DH carriagereturn), 10 (0AH line feed), 42 (2AH *) and 38 (26H &). If theinstantaneous velocity of No. 12345 flowmeter is to be accessed, thecommand W12345DV(CR) can be issued. Corresponding binary code is57H, 31H, 32H, 33H, 34H, 35H, 44H, 56H and 0DH

Function sign &Function sign & can add up to 5 basic commands (Prefix P is allowed)together to form a compound command sent to the flowmeter together.The flowmeter will answer simultaneously. For example, if No. 4321flowmeter is requested to simultaneously return: 1] instantaneous flow, 2]instantaneous flow velocity, 3] positive total flow, 4] energy total, 5] AI1analogous input current value, the following command is issued:W04321PDQD&PDV&PDI+&PDI-&PDIN(CR)Simultaneously returned data are likely as follows:+0.000000E+00m3/d!

9.3.2. MODBUS communication protocolThis MODBUS Protocol uses RTU transmission mode. The Verification Code usesCRC-16-IBM (polynomial is X16+X15+X2+1, shield character is 0xA001) which is



gained by the cyclic redundancy algorithm method. MODBUS RTU mode useshexadecimals to transmit data.This MODBUS-I Protocol uses RTU transmission mode. The Verification Codeuses CRC-16-IBM (polynomial is X16+X15+X2+1, shield character is 0xA001)which is gained by the cyclic redundancy algorithm method. MODBUS-I RTUmode uses hexadecimals to transmit data.

Chapter 10 Appendix2-Insertion transducer


Chapter 10 Appendix2-Insertion transducer10.1. Overview

W210 type insertion transducers can be installed into metal pipelines via anisolation ball valve (installation into pipelines of plastic or other materials mayrequire an optional mounting seat). The maximum pipe diameter in which insertiontransducers can be installed is DN2000. Fluid temperature range: +10℃~+80oC.

Sensor cable length (9m standard) normally can be extended to as long as 100m.Figure 1 shows a diagram of the W210 Insertion Transducer. The insertiontransducer is attached to its mounting base (which is welded to the pipe section atthe measurement point) via a ball valve. When the transducer is removed, pipefluids can be contained by shutting off the ball valve. Therefore, installation andextraction of the transducer can be performed without relieving pipeline pressure.An O-ring seal and joint nut guarantee user safety while installing or operating thetransducer.

10.2. Measurement point selection

To guarantee highly accurate measurement results, it is necessary to select anappropriate measurement point before installing the transducer. For examples ofmeasuring point selection, see the related section in the manual.



10.3. Determining transducer spacing& transducer installation

The mounting space of insertion transducer is the center-to-center hole distancebetween the two transducers (please refer to Menu 25). After enter the rightparameter, please check the mounting space in Menu 25. (unit: mm)Mounting method:1. Drilling at the measuring point, the diameter of the drilling hole is 24mm. Beforedrilling, please make the hole center of transducer mounting base aim at thedrilling hole center, and then weld it on the pipe vertically.(When the flowmeterneed to be hot-tapped into the pipe under pressure without flowinterruption,please refer to the Sitelab’ operation construction of DDK electricHot-tapping or corresponding equipment.)

2. Close the ball valve and screw it tightly on the mounting base.3. Twist off the locknut and loose the lock ring, pull the transducer into the joint nut,and then screw up the joint nut on the ball valve.

4. Open the ball valve and insert the transducer, measure the dimension from theouter surface of the pipe to the front end surface of handspike position to meetthe following formula:H=175-dIn this formula:H is Mounting height (mm);175 is Transducer length (mm);d is Pipe wall thickness(mm);

5. Attach the lock ring to the joint nut by fitting its pinhole in the locating pin, thentighten the screw slightly and turn the orientation handle until it points at themiddle position between the two transducers and its axes matches the axes ofthe pipeline. Finally, tighten the locking screw and screw the locating sleeveonto the joint nut.

6. Connect the transducer cables to the corresponding upstream/downstream(upstream=red, downstream=blue) terminal ends.

7. Please refer to the following installation diagram:



10.4. Transducer mounting methods

W210 insertion transducer mounting method: Z method through M24, it should beinstalled according to the specific application condition.

ImportantFor horizontal pipelines, transducers must be fixed on the sides of the pipe (i.e. at the 3and 9 o’clock position of the pipe) to prevent signal attenuation caused by sediment onthe bottom of the pipe or air bubbles and air pockets in the top of the pipe.
