Attention!

Always press the ENTER key first if you want to change a parameter. If "Change" is still not possible after pressing the ENTER key, this means that the system is locked by a password. To unlock, select "Unlock" in window M54 and enter the password you have previously specified.

6 Sensor installation

6.1 Selection of the measuring location

The installation of the PCE-TDS 75 is very simple. You only need a suitable measuring location, then attach the sensors to the pipe and start the measurement. The following must be observed when selecting a suitable installation location:

• Select a pipe section that is always filled with liquid, e. g. a vertical pipe with flow upwards or a full horizontal pipe.

• Ensure a sufficiently straight pipe length for the installation of the upstream and downstream sensors.

• In the case of a horizontal pipe, the sensors should be mounted on the side to prevent air bubbles at the top or deposits at the bottom from falsifying the measurement result.

• Make sure that the temperature of the measuring location is below the temperature limits of the sensors.

• The inside of the pipe should also be in good condition. If possible, choose a section of pipe where the interior is free from corrosion.

• The section must be sound-conducting.

6.2 Mounting the sensors

Make sure that the pipe surface where the sensors are to be mounted is clean and smooth. There should also be no rust or loose paint on it. Select a suitable section and do not forget to apply the coupling gel. Apply the coupling gel to the centre of each sensor’s front surface and to the pipe surface. Ensure that there are no air bubbles between the sensors and the pipe wall, then attach the sensors to the pipe using the pipe clamps provided and tighten them securely.

Note: The two sensors should be mounted laterally and centrally on horizontal pipes. Make sure that the mounting direction of the sensors is parallel to the flow. If the sensors cannot be mounted horizontally symmetrically due to limited local installation conditions, it may be necessary to mount the sensors at a location where the pipe is always filled with liquid.

6.2.1 Sensor spacing

The distance between the ends of the two sensors can be looked up in M14 (menu 14). After entering the required parameters, check the data displayed in window M14 and adjust the spacing between the sensors according to the data.

6.2.2 Selection of the measuring method

There are two mounting methods you can use depending on the measurement environment: the V method (reflect method) and the Z method (direct method). The V method is easy to install and suitable for most ultrasonic environments, the Z method has a stronger signal and works better in complicated measurement environments.

V method

The V method is considered the standard method. It is practical to use. Nevertheless, it must be ensured that the pipe is mounted correctly (see 6.2 ff.).

Z method

If the pipe diameter is too large or the lining is too thick, it is recommended to use the Z method. The signal transmitted after a Z-method installation has less attenuation than a signal transmitted using the V method. This is because the Z method uses a directly transmitted (rather than reflected) signal that passes through the medium only once. With the Z method, you can measure on pipe diameters ranging from 100 to 5000 mm (4 ... 200 in.). Therefore, we recommend the Z method for pipe diameters over 300 mm (12 in.).

6.2.3 Inspection

Verify that the sensors are properly installed and that there is an accurate and strong ultrasonic signal that ensures proper operation and high reliability of the sensors. This can be confirmed by checking the detected signal strength, the total transit time, the delta time as well as the transit time ratio. The following inspections must be made to ensure high reliability of the measurement and long-term operation of the device.

Signal strength

The signal strength can be checked in window M04. Here, you can see the strength of the signal of both sensors. The signal strength is indicated by numbers from 00.0 to 99.9. 00.0 stands for no detected signal, while 99.9 stands for the maximum signal strength. The stronger the detected signal strength, the longer the device works reliably and the more stable the obtained measured value will be. Position the sensors optimally and check whether sufficient coupling gel was applied during installation to obtain the maximum signal strength. The system requires a signal strength of more than 75.0 for both sensors. If the determined signal strength is too low, the position of the sensors and the spacing should be re-adjusted and the pipe re-inspected. You can also change the mounting method to rectify this problem.

Signal quality

The signal quality or Q value is displayed in window M04. It indicates the level of the detected signal. The Q value is indicated by numbers from 00 to 99. 00 represents the weakest detected signal whereas 99 represents the maximum. The position of the sensors should be adjusted until the detected signal quality is as strong as possible.

Total time and delta time

The total transit time and the total transit time difference, which are displayed in window M04, are further factors for the measurement accuracy. The measurement calculations in the flow meter are based on these two parameters. Therefore, if the total transit time difference varies greatly, it means that the detected signal quality is too poor. This may be the result of poor pipe installation conditions, inadequate sensor installation or incorrect parameter entry. In general, the variation of the total transit time difference should be less than ±20 %. Only if the pipe diameter is too small or the velocity too low, the variation can be larger.

Transit time ratio

The transit time ratio indicates whether the mounting distance of the sensors is accurate. The normal transit time ratio should be 100 ±3 % when properly installed. Check this in window M04. If the transit time ratio exceeds 100 ±3 %, a check is required:

• whether the parameters (pipe outside diameter, wall thickness, pipe material, lining, etc.) have been entered correctly,

• whether the mounting distance of the sensors corresponds to the display in window M14,

• whether the sensors are correctly positioned on the pipe,

• whether the shape of the pipe is distorted or deformed.

6.2.4 Warnings

The pipe parameters must be entered accurately or the flow meter will not work properly.

• During installation, apply enough coupling gel to mount the sensors to the pipe wall. While checking the signal strength and Q value, slowly move the sensors across the mounting location until the strongest signal and maximum Q value are reached. Note that the larger the pipe diameter, the more the sensors need to be moved.

• Check that the mounting distance matches the indication in window M14 and that the sensors are mounted centrally on the pipe on the same pipe size.

• Pay special attention to pipes with seams as such pipes are usually uneven. If the signal strength is always displayed as 0.00, this means that no signal is detected. Therefore, it is necessary to check whether the parameters (including all pipe parameters) have been entered correctly. Check that the sensor mounting method is correct, the pipe is not worn and the lining is not too thick. Make sure that there is actually fluid in the pipe or that the sensors are not too close to a valve or manifold and that there are not too many air bubbles in the fluid, etc. If still no signal is detected, the measuring location must be changed.

• Make sure that the PCE-TDS 75 can operate properly and with high reliability. The stronger the signal strength displayed, the higher the achieved Q value. The longer the flow meter runs accurately, the higher the reliability of the displayed flow rates. If there is interference from electromagnetic waves in the environment or the detected signal is too weak, the displayed flow rate value is not reliable; consequently, reliable operation is not guaranteed under these circumstances.

7 Operation

7.1 Normal operation

When the letter "*R" appears on the display, this indicates that the system is operating normally. When the letter "D" is displayed, this indicates that the system is adjusting the signal gain before measurement. This also means that the system is operating normally. The letter "E" indicates that no signal is detected. Check that the wiring connections of the sensors are correct, firmly installed, etc. For more information, refer to "Troubleshooting".

7.2 Limit value for lowest flow rate

The value in M21 is the minimum value for the flow rate. If the flow falls below this value, the flow display will be set to zero. This feature can prevent the flow meter from displaying the flow as "0" after a pump has been turned off but when there is still fluid movement in the pipe, resulting in a cumulative error. In general, it is recommended to enter 0.03 m/s as the minimum value for the lowest flow. The limit value is not related to the measurement results once the velocity increases above the limit value.

7.3 Zero setting

As soon as a zero flow occurs, a zero point is displayed on the flow meter but the displayed measured value is not equal to "0", this value only indicates "zero". To any measuring instrument, it applies that the smaller the zero point is, the better the quality will be. If the zero point is too high, this means that the quality of the instrument is poor. If the zero set value is not at the true zero flow, a measurement difference may occur. The smaller the physical measurement capacity, the greater the measurement difference from the zero point. It is necessary to perform a zero calibration to improve measurement accuracy at low flow. This can be done via the M22 menu. Go to the "Cutoff" submenu and select "Yes". The instrument will now start the zero calibration. The device will indicate when zero calibration is complete.

7.4 Scaling factor

The scaling factor describes the relationship between the "actual value" and the "read value". For example, if the reading is 2.00 and is indicated as 1.98 on the device, the scaling factor is 2/1.98. This means that the best scaling factor is a constant 1. However, it is difficult to keep the scaling factor "1" on the instrument, especially for serial measurements. During operation, there are still possible differences in pipe parameters, etc. The "scaling factor" may be required when the PCETDS 75 is used for different pipes. Therefore, the scaling factor calibration is specifically designed to calibrate the differences resulting from the application on different pipes. The scaling factor entered must be the one resulting from the actual flow calibration. The scale factor can be entered in window M26.

7.5 System lock

The system lock is intended to prevent operating errors due to tampering by unauthorized personnel. M54 is the system lock menu which you can only unlock with the password you set. When "Lock" is displayed, enter the correct password. Remember the password or keep it in a safe place, otherwise the device can no longer be used.

7.6 Current loop output

With a current loop output, the flow meter is programmable and configurable with outputs such as 4 – 20 mA or 0 – 20 mA. This can be selected in menu 32. For example, if the flow range is 0 ... 1000 m3/h, enter 0 for "Range" and "LowerL" and 1000 for "UpperL". For "Mode", set 4-20 mA. If the flow is within the range -1000 … 2000 m 3/h, select the 20 - 4 - 20 mA output for "Mode". Enter 1000 for "Range" and "LowerL" and 2000 for "UpperL". If the flow direction is relevant, the 0 - 4 - 20 mA output is available. When the flow direction is indicated as negative, the current output is within the range of 0 … 4 mA, whereas the 4 … 20 mA is for the positive direction. The options for the output mode are displayed in the M32 window under "Mode". Calibration and testing of the current loop are performed in the M32 window under "Check". Perform the steps as follows: "check 4mA", "check 8mA", "check 16mA", "check 20mA". Connect an ammeter to test the current loop output and calculate the difference. Calibration of the 4-20 mA output is possible in menu M62.

7.7 Frequency output

The PCE-TDS 75 flow meter is equipped with a transmission function with frequency output. The displayed high or low frequency output indicates the high or low flow rate reading. The user can set both the frequency output and the flow rate according to their requirements. E. g., if a pipe flow range is 0 ... 5000 m3/h, the required relative frequency output is 100 ... 1000 Hz. The configuration is as follows:

• In window M33 "LowerL" (lower limit value of the output flow frequency), select "0";

• Select "5000" for "UpperL" (upper limit of output flow frequency);

• Select "Mode-Frange" and enter "100" and "1000";

• Select "Mode Option" and enter "a. Flow Rate";

7.8 Totalizer pulse output

Each time the flow meter reaches a consistent flow, it can generate a totalizer pulse. The totalizer pulse can be transmitted to a remote counter via OCT (Open Collector Transistor) or a relay. Therefore, it is necessary to configure the OCT and relay accordingly (see windows M33 and M34). For example, if it is necessary to transmit the positive totalizer pulse via a relay and each pulse represents a flow of 10 m3, configure as follows:

• Open M41 and select the totalizer flow unit "m 3";

• go to M41-MULT and select the scaling factor "e. x10";

• in M34-Option, select "g. POS Total".

Attention!

Make sure to select a suitable totalizer pulse. If the totalizer pulse is too high, the output cycle will be too long; if the totalizer pulse is too low, the relay will operate too fast. You can shorten the life of the relay and skip some pulses. It is recommended that the totalizer transmits within the range of 1 ... 3 pulses per second.

7.9 Alarm programming

The on-off alarm is generated by the OCT or by transmission to an external circuit by opening or closing a relay. The on-off output signal is activated under the following conditions:

• Signal not detected.

• Bad signal detected.

• The flow meter is not ready for normal measurement.

• The flow is in reverse direction (backflow).

• The analogue outputs exceed the measuring span by 120 %.

• The frequency output exceeds the span by 120 %.

• The flow rate exceeds the configured ranges. Configure the flow ranges using the

software alarm system. There are two software alarms: alarm no. 1 and alarm no. 2. Example 1: If the flow rate exceeds 300 ... 1000 m3/h, follow these steps to program the relay output alarm:

(1) In menu 35, set Alarm1 LowL to 300. (2) In menu 35, set Alarm1 Upper to 1000.

(3) Select d. Alarm1 under Option in Menu 34.

7.10 4-20 mA analogue output calibration Attention!

Each flow meter has been calibrated before leaving the factory. It is not necessary to perform this step unless the current value (determined during current loop calibration) displayed in the M32 window is not identical to the actual output current value.

The hardware detection window must be activated before calibrating the analogue output. To do this, you must proceed as follows:

Open M62 for 4-20 mA calibration. Use "↑" and "↓" to toggle. Calibrate the 4 mA output of the current loop. Use an ammeter to measure the current loop output current while adjusting the numerical values until the ammeter reads 4.00. The 4 mA output value has now been calibrated. Use "↑" and "↓" to toggle and calibrate the 20 mA output of the current loop. The method is the same as for the 4 mA calibration. The results are automatically saved to the EEPROM and are not lost even when the power is turned off.

7.11 ESN

We equip the flow meter with a unique electronic serial number to identify each flow meter for the benefit of the manufacturer and customers. The ESN, device types and versions can be viewed in window M50.

M01 Flow rate

Displays the flow rate and the absolute flow. Displays the velocity. Flow rate and velocity change every 6 seconds. Press ENTER to pause the change.

M04 Status

The inlet direction signal strength and the outlet direction signal strength are displayed. The signal quality Q is indicated as 00 ... 99. 00 represents the worst signal while 99 represents the best signal. Normally, the signal quality Q value should be above 60.

Display of the measured liquid sound velocity. Normally, this value should be approximately equal to the value entered in window M12. If the difference is too large, this is probably due to an incorrect value entered in window M12 or improper installation of the sensors.

Displays the measured and the calculated transmission time. The difference should be as small as possible. The ratio should be a maximum of 100 ±3 %. If the difference is too large, check that the parameters have been entered correctly, especially the sound velocity of the liquid.

Displays the measured ultrasonic averaging time (unit: µs) and the delta time of the upstream and downstream time (unit: ns). The velocity calculation in the flow meter is based on the two measured values. The delta time is the best indication of whether the device is running stably. Normally, the variation of the delta time should be less than 20 %. If this is not the case, check whether the sensors are installed correctly or whether the parameters have been entered correctly.

M14 Installation spacing

This value is calculated by the PCETDS 75. The user must mount the sensors according to the displayed sensor spacing (make sure that the sensor spacing is measured accurately during installation). The system will automatically display the data after the pipe parameter is entered.

M20 Damping

The damping factor ranges from 1 to 999 seconds. 1 means no damping; 999 means maximum damping. The damping function stabilizes the flow display. Typically, a damping factor of 3 to 10 is recommended for applications.

M21 Low Vel. Cutoff

The low flow cutoff is used to make the system display 0 at minimum flow. For example, if the minimum value is set to 0.03, the system will regard all measured flow rate values from -0.03 to + 0.03 as "0". In general, a value of 0.03 is recommended for most applications.

M22 Zero Settings

When the fluid is in a static state, the displayed value is called zero point. If the zero point in the flow meter is not zero, the difference is added to the actual flow values and measurement differences occur in the flow meter.

The zero point must be set after the sensors are installed and the flow in the pipe is in absolute static condition (no fluid movement in the pipe). In this way, the zero point resulting from different pipe mounting locations and parameters can be eliminated. This increases the measurement accuracy at low flow and eliminates the flow offset. Select "Yes"; reset the zero point set by the user.

This method is not frequently used. The zero point should only be adjusted when all other methods do not lead to a solution. Manually enter the value you wish to add to the measured value to obtain the actual value. For example Actual measured value ＝240 m3/h

Value deviation ＝250 m3/h Flow meter display ＝250 m3/h Normally, the value is set to "0". Use

"↑" and "↓" to toggle.

9 Troubleshooting

The PCE-TDS 75 has advanced self-diagnostic functions and displays any errors in the upper right corner of the LCD screen via unique codes in date/time order. Errors caused by improper operation, incorrect settings and unsuitable measurement conditions can be displayed accordingly during operation. This function helps the user to detect errors and find the causes quickly. Thus, problems can be solved promptly according to the following chart. If a problem cannot be solved, contact PCE Instruments.

9.1 Error codes during operation

Codes

Causes

Solutions

The system is running normally.

- Signal not detected.

- The distance between the sensors is not correct or not enough coupling gel has been applied to the sensors.

- The sensors are not installed correctly.

- The wall is too thick.

- The thickness of the pipe liner was incorrectly specified.

- Attach the sensors to the pipe and tighten them firmly with the clamps. Apply a generous amount of coupling gel to the sensors and the pipe wall.

- Remove rust or loose paint from the pipe surface. Clean it thoroughly.

- Check the entered parameter settings.

- Select a new pipe section. The instrument may be run properly in a new location.

- Wait after setting the parameters again. Normally, the device should function normally afterwards.

9.2 Frequently asked questions

Question:

New pipe and all installation requirements are met: Why is still no signal detected? Help:

Check the pipe parameter settings, installation method and wiring connections. Make sure that sufficient coupling gel has been applied, the pipe is filled with fluid, the distance between the sensors matches the value displayed in M14 and the sensors are installed in the correct direction.

Question: Old pipe with contamination inside, no or bad signal detected: How to solve the problem?

Help: Check that the pipe is filled with fluid. Try the Z method for installing the sensors. Carefully select a good section of pipe and clean it completely, apply enough coupling gel to each sensor face and install the sensors properly. Slowly and carefully move each sensor against each other around the installation point until maximum signal is achieved. Make sure that the new installation point inside the pipe is not contaminated and that the pipe is concentric (not distorted) so that the sound waves are not reflected outside the intended area.

Question: Why is the CL output (current loop mode) abnormal?

Help: Check whether the output mode is set correctly in window M32 under "Mode". Check whether the maximum and minimum current values are set correctly in window M32 under "Range". Recalibrate the current loop and check this in window M32 under "Check".

Question: Why is the flow rate still displayed as zero even though there is obviously fluid in the pipe and the "R" symbol is displayed on the screen?

Help: Check whether the "zero setting" was performed when the flow was not zero (see window M22). If this is the case, restore the factory setting in window M22-Reset.

10 Appendix - Use and communication protocol of serial interface

network

10.1 Overview

The flow meter has a communication protocol. It can be connected to a RS-485 Modbus. Two basic schemes can be selected for networking, i. e. the analogue current output method with the flow meter only or the RS232 communication method via the serial port directly from the flow meter.

When the serial port communication method is used directly to implement a monitoring network system, the address identification code of the flow meter is used as a network address code. An extended command set with [W] is used as the communication protocol.

RS-232 (cable length 0 ... 15 m) or RS-485 (cable length 0 ... 1000 m) can be used directly for data transmission links for a short distance. Current loop can be used for medium or long-distance transmission.

When the flow meter is used in a network environment, various operations can be performed by a host device, except for programming the address identification code, which must be done via the flow meter keypad. For data transmission, the command answer mode is used, i.e. the host device issues commands and the flow meter responds accordingly.

Attention!

RS232 serial communication and RS485 communication cannot be used simultaneously with the functions available in the communication protocol.

10.2 Definitions of the serial port

10.3 Direct connection to the host device via RS232

10.4 Communication protocols and their use

The flow meter supports these three communication protocols: FUJI protocol, MODBUS-C protocol, MODBUS-I protocol.

10.4.1 HL protocol

The host device requests the flow meter to respond by sending a command. The baud rate of asynchronous communication (primary station: computer system; secondary station: ultrasonic flow meter) is generally 9600 BPS. A single byte has the 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 the data string is flexible. The order applies to both RS232 and RS485. Some frequently used commands are listed in the following chart:

Prefix of return command with check

Note 5

Networking command prefix of numeric string address

Note 6

Notes:

1. (cr) expresses the carriage return (ENTER). Its ASCII value is 0DH. (lf) expresses the line feed.

Its ASCII value is 0AH.

2. d expresses a number from 0 ... 9. The value 0 is expressed as +0.000000E+00.

3. There is no decimal point in the integral part before E.

4. dddddddd represents the serial number of the instrument, t represents the model of the

instrument.

5. The character P can be added before every basic command. It means that the transmitted data

has CRC verification. The verification method is to add all data back to the data that is cumulative and binary and the 8-bit binary data is taken. For example, the return information of the RT (cr) (lf) is : +1234567E+0m3 (cr) (lf), (the relative binary system data is : 2BH, 31H, 32H, 33H, 33H, 34H, 35H, 36H, 37H, 45H, 2BH, 30H, 6DH, 20H, 20H, 0DH, 0AH). The sum of all its return data is =2BH+31H+32H+33H+34H+34H+35H+ 36H+37H+45H+2BH+30H+6DH+33H +20H=2F7, the low 8-bit data of its binary is F7. Therefore, the data of the order PRT (cr) (lf) is called + 1234567E + 0m3!F7 (cr) (lf), "!" For delimiters, the preceding character is the character of summation, followed by a check code of 1 byte.

6. Use of prefix W: W + numeric string address code + basic command. The numeric string value

range is 0 … 255, except 13 (0DH carriage return), 10 (0AH line feed). If the instantaneous velocity of flow meter no. 123 is to be accessed, the command W123DV (cr) (lf) can be issued. The corresponding binary code is 57H, 31H, 32H, 33H, 44H, 56H, 0DH, 0AH; only the same device with the same address of the Internet address and command will return the data.

7. W and P commands can be used in combination, for example W123PRT +. This means that

the device reading the network address is the cumulative value of the device with 123 and its return data has eight accumulations and checksums. "s" expresses ON or OFF or UD. For example, "TR:ON, RL:ON" expresses that the OCT and relay are in an actuated state; "TR:UD， RL:UD" expresses that the OCT and relay are not actuated.

10.4.2 MODBUS-I communication protocol

This MODBUS-I protocol uses RTU transmission mode. The verification code uses CRC-16-IBM (polynomial is X16+X15+X2+1, shield character is 0xA001) gained by cyclic redundancy algorithm method. MODBUS-I-RTU mode uses hexadecimal numbers for data transmission.

CRC ( Verify )

The range of flow meter addresses is 1 … 247 (hexadecimal: 0x01 - 0xF7) and can be checked in menu 46. For example, the decimal number "11" displayed in menu 46 means that the flow meter address in the MODBUS protocol is 0x0B. The CRC verification code adopts CRC-16-IBM (polynomial is X16+X15+X2+1, shield character is 0xA001) gained by the cyclic redundancy algorithm method. The low byte of the verification code is at the beginning, while the high byte is at the end. For example, to read the address 1 (0x01) in RTU mode if the instantaneous flow rate uses hour

as unit (m3/h), that is, i. e. reads 40005 and 40006 register data, the read command is as follows:

13 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either reuse them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.

If you have any questions, please contact PCE Instruments.
