2.3. Measurement Site Selection
The installation of this ultrasonic flow meter is the simplest one of all kinds of flowmeters. Only one suitable
measuring site needed, plug the transducers on the pipe and then start the measurement.
When selecting a measurement site, it is important to select an area where the fluid flow profile is fully developed
to guarantee a highly accurate measurement. Use the following guidelines to select a proper installation site:
Reversion: 3.0.1
Page 12 of 79
SL1188 Ultrasonic Flowmeter
l
Choose a section of pipe that is always full of liquid, such as a vertical pipe with flow in the upward direction
or a full horizontal pipe.
l
Ensure enough straight pipe length at least equal to the figure shown below for the upstream and downstream
transducers installation. Try to avoid Ensure enough straight pipe length at least equal to the figure shown
below for the upstream and downstream transducers installation.
l
On the horizontal pipe, the transducer should be mounted on the 9 and 3 of the pipe, avoiding the position of
6 and 12, in case of the signal attenuation caused by pipe at the bottom sediment or bubble、cavitation on the
pipe.
l
Ensure that the measuring site temperature is under the transducer temperature limits.
l
Consider the inside condition of the pipe carefully. If possible, select a section of pipe where the inside is free
of excessive corrosion or scaling.
l
Choose a section of sound conducting pipe.

3. Transducer Installation
3.1. Transducer Installation
Before installing the transducers, clean the pipe surface where the transducers are to 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 a wide band of sonic coupling compound down the center of the face of each transducer as
well as on the pipe surface, ensure there are no air bubbles between the transducers and the pipe wall, and then
attach the transducers to the pipe with the straps provided and tighten them securely.
Note: The two transducers should be mounted at the pipe’s centerline on horizontal pipes.
Make sure that the transducer mounting direction is parallel with the flow.
During the installation, there should be no air bubbles or particles between the transducer and the pipe wall. On
horizontal pipes, the transducers should be mounted in the 3 o’clock and 9 o’clock positions of the pipe section in
order to avoid any air bubbles inside the top portion of the pipe. (Refer to Transducer Mounting). If the
transducers cannot be mounted horizontally symmetrically due to limitation of the local installation conditions, it
may be necessary to mount the transducers at a location where there is a guaranteed full pipe condition (the pipe is
always full of liquid).
3.1.1 Transducer Spacing
The spacing between the ENDS of the two transducers is considered as the standard transducer spacing ( Refer to
MENU25 ). After entering the required parameters, Check the data displayed in Window M25 and adjust the
transducers spacing according to the data displayed in Windows M25.
3.1.2 Transducer Mounting Methods
Three transducer mounting methods are available. They are respectively: V method, Z method and N method.
The V method is primarily used on small diameter pipes (DN100 ~ 300mm, 4〞 ~ 12〞). The Z method is used
in applications where the V method cannot work due to poor signal or no signal detected. In addition, the Z
method generally works better on larger diameter pipes (over DN300mm, 12〞) or cast iron pipes.
The N method is an uncommonly used method. It is used on smaller diameter pipes (below DN50mm, 2〞).
3.1.3 V Method
The V method is considered as the standard method. It usually gives a more accurate 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 and equal spacing on
either side of the centerline.

3.1.4 Z Method
The signal transmitted in a Z method installation has less attenuation than a signal transmitted with the V method
Reversion: 3.0.1
Page 14 of 79
SL1188 Ultrasonic Flowmeter
when the pipes are too large, there are some suspended solid in the fluid, or the scaling and liner are too thick .
This is because the Z method utilizes a directly transmitted (rather than reflected) signal which transverses the
liquid only once. The Z method is able to measure on pipe diameters ranging from 100mm to 5000mm ( 4 inch to
200 inch ) approximately. Therefore, we recommend the Z method for pipe diameters over 300mm (12 inch).
3.1.5 N Method (not commonly used)
With the N method, the sound waves traverse the fluid three times and bounce twice off the pipe walls. It is
suitable for small pipe diameter measurement. The measurement accuracy can be improved by extending the
transit distance with the N method ( uncommonly used ).
3.2. Transducer Mounting Inspection
Check to see if the transducer is installed properly and if there is an accurate and strong enough ultrasonic signal
to ensure proper operation and high reliability of the transducer. It can be confirmed by checking the detected
signal strength, total transit time, delta time as well as transit time ratio.
The "mounting" condition directly influences the flow value accuracy and system long-time running reliability. In
most instances, only apply a wide band of sonic coupling compound lengthwise on the face of the transducer and
stick it to the outside pipe wall to get good measurement results. However, the following inspections still need to
be carried out in order to ensure the high reliability of the measurement and long-term operation of the instrument.
3.2.1 Signal Strength
Signal strength (displayed in Window M90) indicates a detected strength of the signal both from upstream and
downstream directions. The relevant signal strength is indicated by numbers from 00.0 ~ 99.9. 00.0 represents no
signal detected while 99.9 represents maximum signal strength. Normally, the stronger the signal strength detected,
the longer the operation of the instrument reliably, as well as the more stable the measurement value obtained.
Adjust the transducer to the best position and check to ensure that enough sonic coupling compound is applied
adequately during installation in order to obtain the maximum signal strength.
System normally requires signal strength over 60.0, which is detected from both upstream and downstream
directions. If the signal strength detected is too low, the transducer installation position and the transducer
mounting spacing should be re-adjusted and the pipe should be re-inspected. If necessary, change the mounting
method to be Z method.
3.2.2 Signal Quality (Q value)
Q value is short for Signal Quality (displayed in Window M90). It indicates the level of the signal detected. Q
Reversion: 3.0.1
Page 15 of 79
SL1188 Ultrasonic Flowmeter
value is indicated by numbers from 00 ~ 99. 00 represents the minimum signal detected while 99 represent the
maximum. Normally, the transducer position should be adjusted repeatedly and coupling compound application
should be checked frequently until the signal quality detected is as strong as possible.
3.2.3 Total Time and Delta Time
"Total Time and Delta Time", which displays in Window M93, indicates the condition of the installation. The
measurement calculations in the Flowmeter are based upon these two parameters. Therefore, when "Delta Time"
fluctuates widely, the flow and velocities fluctuate accordingly, this means that the signal quality detected 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 pipe diameter is too small or
velocity is too low can the fluctuation be wider.
3.2.4 Transit Time Ratio
Transit Time Ratio indicates if the transducer mounting spacing is accurate. The normal transit time ratio should
be 100+/-3 if the installation is proper. Check it in Window M91.
Attention
If the transit time ratio is over 100±3, it is necessary to check:
(1)
If the parameters (pipe outside diameter, wall thickness, pipe material, liner, etc.) have
been entered correctly,
(2)
If the transducer mounting spacing is accordance with the display in Window 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.
3.2.5 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 Q value, move the transducers slowly around the
mounting site until the strongest signal and maximum Q value can be obtained. Make sure that the
larger the pipe diameter, the more the transducers should be moved.
(3)
Check to be sure the mounting spacing is accordance with the display in Window M25 and the
transducer is mounted at the pipe’s centerline on the same diameter.
(4)
Pay special attention to those pipes that formed by steel rolls (pipe with seams), since such pipe is
always irregular. If the signal strength is always displayed as 0.00, that means there is no signal
detected. Thus, it is necessary to check that the parameters (including all the pipe parameters) have
been entered accurately. Check to be sure the transducer mounting method has been selected properly,
the pipe is not worn-out, and the liner is not too thick. Make sure there is indeed fluid in the pipe or
the transducer is not too close to a valve or elbow, and there are not too many air bubbles in the fluid,
etc. With the exception of these reasons, if there is still no signal detected, the measurement site has
to be changed.
(5)
Make sure that the Flowmeter is able to run properly with high reliability. The stronger the signal
strength displayed, the higher the Q value reached. The longer the Flowmeter runs accurately, the
higher the reliability of the flow rates displayed. If there is interference from ambient electromagnetic
waves or the signal detected is too poor, the flow value displayed is not reliable; consequently, the
capability for reliable operation is reduced.
(6)
After the installation is complete, power on the instrument and check the result accordingly.

4.1. System Normal Identification
0 8 keys. If the letter "*R" displays on the screen, it indicates system normal.
Press the
If the letter "G" is displayed, it indicates that system is adjusting the signal gain prior to the measurement. Also, it
means system normal. Only when the adjustment takes too long without stopping, can system be identified as
abnormal.
Letter "I" indicates no signal is being detected. Check the transducer wiring connections are correct, the
transducers are installed firmly, etc.
Menu
For further information, please refer to "Error Diagnosis".
4.2. Low Flow Cutoff Value
The data in M41 is Low Flow Cutoff Value. If the flow rate falls below the low flow cutoff value, the flow
indication is driven to zero. This function can prevent the flow meter from displaying flow as "0"after a pump was
shut down, but there is still liquid movement in the pipe, which will result in cumulative error. Generally, 0.01m/s
is recommended to enter as the low flow cutoff point.
The low flow cutoff value has no relation to the measurement results once the velocity increases over the low flow
cutoff value.
4.3. Zero Settings
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 is poor.
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 definite degree, as compared with the physical measurement capacity, can the measuring
difference from zero point be ignored.
For an ultrasonic Flowmeter, the measurement error from zero point cannot be ignored under low flow conditions.
It is necessary to perform a static zero set calibration to improve low flow measurement accuracy.
Set Zero in Menu42, firstly press Enter key, and then wait for the processing indication displayed at the lower right
corner reducing to be "0". Performing Set Zero in flowing conditions may cause the flow to be displayed as "0". If
so, it can be recovered via Menu 43.
4.4. Scale Factor
Scale factor refers to the ratio between "actual value" and "reading value". For example, when the measurement is
2.00, and it is indicated as 1.98 on the instrument, the scale factor reading is 2/1.98. This means that the best scale
factor constant is 1. However, it is difficult to keep the scale factor as "1" on the instrument especially in 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 factor calibration is specially designed for calibrating the differences
that result from application on different pipes. The scale factor entered must be one that results from actual flow
calibration. The scale factor can be input in Window M45.
4.5. System Lock
System lock is intended to prevent operation error due to tampering by unauthorized personnel.

4.6. 4 ~ 20mA Current Loop Output
With a current loop output exceeding an accuracy of 0.1%, the flowmeter is programmable and configurable with
outputs such as 4 ~ 20mA or 0 ~ 20mA selected in Menu 55. For details, please refer to Menu 55 in "Window
Display Explanations".
In Window M56, enter a 4mA flow value. Enter the 20mA flow 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. If the flow ranges
from -1000 ~ 0 ~ 2000m3/h, configure the 20 ~ 4 ~ 20mA output by selecting in Window M55 when flow
direction is not an issue. Enter 1000 in Window M56 and 2000 in Window M57. When flow direction is an issue,
module 0 ~ 4 ~ 20mA is available. When the flow direction displays as negative, the current output is in range of 0
~ 4mA, whereas the 4 ~ 20mA is for the positive direction. The output module options are displayed in Window
M55. Enter "-1000" in Window M56 and 2000 in Window M57.
Calibrating and testing the current loop is performed in Window M58. Complete the steps as follows:
5 8 Enter , move ∧ or ∨ to display "0mA", "4mA", "8mA", "16mA", "20mA" readings, connect
Press
an ammeter to test the current loop output and calculate the difference. Calibrate it if the difference is not within
tolerance. Refer to Section 4.11 for Current Loop Verification.
Menu
Check the present current loop output in Window M59 as it changes along with change in flow.
4.7. Frequency Output
The flowmeter is provided with a frequency output transmitter function. The high or low frequency output
displayed indicates the high or low flow rate reading. The user can reset the frequency output as well as flow rate
as the user’s actual requirements.
For example: if a pipe flow range is 0 ~ 3000m3/h, the relative frequency output required is 123 ~ 1000Hz, 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;
In Window M67 (low limit frequency), input 123; in Window M67 ( high limit frequency ), input 1000.
There is no output circuit specially assigned to frequency output. It only can be transmitted through OCT, i.e.
select Window M78 ( item "13. FO" ).
Typical OCT Output wiring diagram as below:
Reversion: 3.0.1
Page 18 of 79
SL1188 Ultrasonic Flowmeter
4.8. Totalizer Pulse Output
Each time the flowmeter reaches a unit flow, it may generate a totalizer pulse output to a remote counter.
The totalizer pulse output can be transmitted through OCT or a relay. Therefore, it is necessary to configure OCT
and the relay accordingly. (Please refer to Window M78 and M79). For example, if it is necessary to transmit the
positive totalizer pulse through a relay, and each pulse represents a flow of 0.1m3, the configuration is as follows:
In Window M32, select the totalizer flow unit "Cubic Meters (m3)";
In Window M33, select the scale factor "x0.1";
In Window M79, select "9. Positive totalizer pulse output";
Attention
Make sure to select a appropriate totalizer pulse. If the totalizer pulse is too big, the output
cycle will be too long; if the totalizer is too small, the relay will operate too faster, you may
shorten the life of the relay, as well as skip some pulses. The totalizer is recommended to
transmit within the range of 1 ~ 60 pulse per second.
4.9. Alarm Programming
The on-off output alarm is generated through OCT or transmission to an external circuit by opening or closing a
relay. The on-off output signal is activated under the following conditions:
(1) Signal not detected;
(2) Poor signal detected;
(3) The flowmeter is not ready for normal measurement;
(4) The flow is in the reverse direction (back flow).
(5) The analog outputs exceed span by 120%.
(6) The frequency output exceeds span by 120%.
(7) The flow rate exceeds the ranges configured (Configure the flow ranges using the software alarm system.
There are two software alarms: Alarm#1 and Alarm #2. The lower limit value for Alarm#1 is configured
in Window M73, and the upper limit value is configured in Window M74. As for Alarm#2, the lower
limit value is in M75 and the upper one is in Window M76).
Example 1: When flow rate exceeds 300 ~ 1000 m3/h, in order to program the relay output alarm, Complete the
steps as follows:
(1) In Window M73, input 300;
(2) In Window M74, input 1000;
(3) In Window M79, select item 6: "6. Alarm #1 limit exceed".
Example 2: To program OCT output alarm signal, when flow rate exceeds 100 ~ 500 m3/h; and to relay output
alarm signal, when flow rate exceeds 600 ~ 1000 m3/h, complete the steps as follows :
(1) In Window M73, input 100;
(2) In Window M74, input 500;
(3) In Window M75, input 600;
(4) In Window M76, input 1000;
(5) In Window M78, select item 6: "6. Alarm #1".
(6) In Window M79, select item 7: "7. Alarm #2".
4.10. Batch Controller
The batch controller is able to perform flow quantity control. The internal batch controller in the flowmeter is able
to be controlled through the keypad. The output can be transmitted through OCT or a relay.
In Window M78 ( OCT output )、M79 ( relay output ) or M80 ( Flow Batch CTRL ), select Item 8 "Batch
controller" and the OCT or relay output will generate output signals.
Reversion: 3.0.1

Display Explanations".
4.11. 4-20mA Analog Output Calibration
Attention
Each flowmeter has been calibrated strictly before leaving factory. It is unnecessary to carry out
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.
The hardware detect window must be activated prior to calibration the Analog Output. The procedure is as
follows:
∨
0 Enter to enter password "115800", then press Enter to activate the detected menu. With no effect
Press
to next power on, this window will close automatically as soon as the power is turned off.
Press ∨ to calibrate the current loop 4mA output. Use an ammeter to measure the output current of current loop.
At the same time, press ∧ or ∨ to adjust the displayed numbers. Watch the ammeter until it reads 4.00. Stop
at this point, the 4mA has been calibrated.
Then, press Enter to calibrate the current loop 20mA output. The method is the same as 4mA calibration.
Menu
The results are automatically saved in EEPROM and won’t lose when power off.

4.12.2 Install or Remove the SD card while the meter is powered on
If the operator desires to insert or remove the SD card with power on, the following operation is to be used:
It is shown as the picture above, move the switch to the "OFF" position. This switch activates the Memory
Logging ONLY; it DOES NOT SECURE POWER TO THE FLOWMETER. It is then safe to remove or install the
SD Card. Once reinstalled, move the switch to the "ON" position, now the SD card can continue to log data.
Attention:
Do not remove the SD card from the reader while actively working with the data. Data should
be saved and stored in a separate location on the PC, and then processed form that file
location. Processing the data directly from the SD card file location on the PC could result in
losing or destroying data if the SD card is removed while still being processed.
4.12.3 Reading the SD Data Internally with the Instrument powered ON

Empty Pipe Setup
This parameter is used to overcome the possible
problems that usually show up when the pipe being
measured is empty. Since signals can be transmitted
through the pipe wall, the flow meter may still read a
flow while measuring an empty pipe. To prevent this
from happening, you can specify a value. When the
signal quality falls below this value, the measurement
stops automatically. If the flow meter is already able to
stop measuring when the pipe is empty, a value in the
range of 30 to 40 should also be entered in this window
to ensure no measurement when the pipe is empty.
It should be understood that the instrument is NOT
designed to function correctly on an empty pipe.

Press ENT to go
When fluid is in the static state, the displayed value is
called "Zero Point". When "Zero Point’ is not at zero in
the flowmeter, the difference is going to be added into
the actual flow values and measurement differences
will occur in the flowmeter.
Set zero must be carried out after the transducers are
installed and the flow inside the pipe is in the absolute
static state (no liquid movement in the pipe). Thus, the
"Zero Point" resulting from different pipe mounting
locations and parameters can be eliminated. The
measuring accuracy at low flow is enhanced by doing
this and flow offset is eliminated.
Press Enter , wait for the processing instructions at the
bottom right corner to reach 0.

The Serial Port controls the output according to the command and parameter entered in the RS232 to output a
definite current value through the current loop. The command formats are narrated in the command explanations
to Serial Port controls. For example, if it is necessary to output a 6mA current through the current loop, it can be
realized by setting Window M56 to the mode "0-20mA Via RS232" and giving a command as "AO6 (CR)". This
function is able to make the flowmeter operate a control valve conveniently.
Other different current output characteristics are displayed in above figures. The user can select one of them
according to his actual requirements.
In six graphs shown above, flow F0mA or F4mA indicates the value that user entered in Window M57; and flow
F20mA indicates the value that customer entered in Window M58. In the 4-20mA and 0-20mA modes, F0mA(or
F4mA)and F20mA can be selected as a positive or negative flow value as long as the two values are not the same. As
for modes 20-4-20mA and 20-0-20mA, the flowmeter ignores the positive and negative value of the actual flow;
therefore, both F0mA (or F4mA) and F20mA must be selected as positive flow values.
In mode 0-4-20mA, F0mA must be select as a negative value and F20mA as a positive value. Furthermore, in mode

6.2. Frequently Asked Questions and Answers
Question: New pipe, high quality material, and all installation requirements met: why still no signal detected ?
Answer:
Check pipe parameter settings, installation method and wiring connections. Confirm if the coupling
compound is applied adequately, the pipe is full of liquid, transducer spacing agrees with the screen
readings and the transducers are installed in the right direction.
Question: Old pipe with heavy scale inside, no signal or poor signal detected: how can 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
a wall, or it is necessary to install the transducers on a vertical or inclined pipe with flow upwards
instead of on a horizontal pipe).
Carefully select a good pipe section and fully clean it, apply a wide band of coupling compound on
each transducer face (bottom) and install the transducer properly.
Slowly and slightly move each transducer with respect to each other around the installation point until
the maximum signal is detected. Be careful that the new installation location is free of scale inside the
pipe and that the pipe is concentric (not distorted) so that the sound waves do not bounce outside of the
proposed area.
For pipe with thick scale inside or outside, try to clean the scale off, if it is accessible from the inside.
(Note: Sometimes this method might not work and sound wave transmission is not possible because of
the a layer of scale between the transducers and pipe inside wall).
Question: Why is the CL output abnormal?
Answer:
Check to see if the desired current output mode is set in Window M55.
Check to see if the maximum and minimum current values are set properly in Windows M56 and M57.
Re-calibrate CL and verify it in Window M59.
Question: Why is the flow rate still displayed as zero while there is fluid obviously inside 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 the pipe (Refer to Window M42).

8. Appendix1 – W210 Insertion Transducer
8.1. Overview
W210 type insertion transducers can be installed into metal pipelines via an isolation ball valve ( installation into
pipelines of plastic or other materials may require an optional mounting seat ). The maximum pipe diameter in
which insertion transducers can be installed is DN2000. Fluid temperature range: +10℃ ~ +80℃. 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 insertion transducer is attached to its mounting
base ( which is welded to the pipe section at the measurement point ) via a ball valve. When the transducer is
removed, pipe fluids can be contained by shutting off the ball valve. Therefore, installation and extraction of the
transducer can be performed without relieving pipeline pressure. An O-ring seal and joint nut guarantee user
safety while installing or operating the transducer.

Important:
For horizontal pipelines, transducers must be fixed on the sides of the pipe ( i.e. at the 3 and 9
o’clock position of the pipe ) to prevent signal attenuation caused by sediment on the bottom of
the pipe or air bubbles and air pockets in the top of the pipe.
8.4. Transducer Mounting Methods
W210 insertion transducer mounting method: Z method through M24, it should be installed according to the
specific application condition.
8.5. Z Mounting Method
Z method is the most commonly used mounting method for insertion-type ultrasonic flowmeters, suitable for pipe
diameters ranging from 50mm to 2000mm. Due to strong signal strength and high measurement accuracy, the Z
method is preferable for pipe sections severely rusted or with too much scale formation on the inside wall. When
installing the transducer using the Z method, be sure that the two transducers and the pipeline center axis are in
the same plane, but never in the 6 or 12 o’clock positions. See below:

make sure it complies with the following formula:
H=265-h
In this formula:
H is Mounting height (mm)
265 is Transducer length (mm)
h is Pipe wall thickness (mm)
5. Attach the lock ring to the joint nut by fitting its pinhole in the locating pin, then tighten the screw slightly and
turn the orientation handle until it points at the middle position between the two transducers and its axes matches
the axes of the pipeline. Finally, tighten the locking screw and screw the locating sleeve onto the joint nut.
6. Connect the transducer cables to the corresponding upstream/downstream (upstream=red, downstream=blue)
terminal ends.
Important
For horizontal pipelines, transducers must be fixed on the sides of the pipe ( i.e. at the 3 and 9
o’clock position of the pipe ) to prevent signal attenuation caused by sediment on the bottom of
the pipe or air bubbles and air pockets in the top of the pipe.

10. Appendix3 – WH Insertion Transducer
10.1 Overview
WH type insertion transducer can be installed into metal pipelines via an isolation ball valve, and it can measure
fluid range from -40 to +150oC. The maximum pipe diameter in which insertion transducers can be installed is
DN5000mm. The insertion transducer length is 237mm. Note that the pipe wall thickness of the pipe section
should not be smaller than 24mm.
Figure 2 shows a diagram of the Insertion Transducer ( Ordering option – WH ). The insertion transducer is
attached to its mounting base ( which is welded to the pipe section at the measurement point ) via a ball valve.
When the transducer is removed, pipe fluids can be contained by shutting off the ball valve. Therefore, installation
and extraction of the transducer can be performed without relieving pipeline pressure. An O-ring seal and joint nut
guarantee user safety while installing or operating the transducer.

10.2 Measurement Point Selection
To obtain the strongest signal strength and the highly accurate measurement results, it is necessary to select an
appropriate measurement point before installing the transducer. For examples of measuring 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 distance between the two transducers
(please refer to Menu 25). After enter the right parameter, please check the mounting space in Menu 25. ( unit:
mm ). Calculate the center-to-center hole distance S between the two transducers by using the formula below:
Reversion: 3.0.1
Page 61 of 79
SL1188 Ultrasonic Flowmeter
S = SP+34 ( Units: mm )
In this formula, SP is the spacing value calculated ( by the flowmeter ) by entering the pipe parameters such as
pipe inner diameter, pipe wall thickness, etc. ( Units in mm ). Mounting method:
Drilling at the measuring point, the diameter of the drilling hole is 40mm. Before drilling, please make the hole
center of transducer mounting base aim at the drilling hole center, and then weld the mounting base of the
transducer vertically at that position on the pipe surface. ( When the flowmeter need to be hot-tapped into the pipe
under pressure without flow interruption,please refer to the Sitelab’ operation construction of DDK electric
Hot-tapping or corresponding equipment. )
Tighten the ball valve securely onto the mounting base ( shut off the ball valve ).
Unscrew the locating sleeve and loosen the lock ring, retract the transducer into the joint nut, and then tighten the
joint nut onto the ball valve.
Open the ball valve and insert the transducer into the pipe. At the same time, measure the dimension between the
outside pipe and the A point (See Figure 2) and make sure it complies with the following formula:
H=237 - h
In this formula:
H is Mounting height (mm)
237 is Transducer length (mm)
h is Pipe wall thickness (mm)
Attach the lock ring to the joint nut by fitting its pinhole in the locating pin, then tighten the screw slightly and
turn the orientation handle until it points at the middle position between the two transducers and its axes matches
the axes of the pipeline. Finally, tighten the locking screw and screw the locating sleeve onto the joint nut.
Connect the transducer cables to the corresponding upstream/downstream (upstream=red, downstream=blue)
terminal ends.
Important
For horizontal pipelines, transducers must be fixed on the sides of the pipe ( i.e. at the 3 and 9
o’clock position of the pipe ) to prevent signal attenuation caused by sediment on the bottom of
the pipe or air bubbles and air pockets in the top of the pipe.

11. Appendix4– Serial Interface Network Use
and Communications Protocol
11.1
Overview
The flowmeter has perfect communication protocol. It can also be connected to a RS-485 bus .
Two basic schemes can be chosen for networking, i.e. the analog current output method only using the flowmeter
or the RS232 communication method via serial port directly from the flowmeter. This method is suitable to
replace dated instruments in old monitoring networks. The later method is used in new monitoring network
systems. It has advantages include low hardware investment and reliable system operation.
When the serial port communications method is directly used to implement a monitoring network system, the
address identification code (in window M46) of the flowmeter is used as a network address code. Expanded
command set with [W] is used as communication protocol. Thus the analog current loop and OCT output of
flowmeter can be used to control the opening/closing of a control valve. The relay output can be used to
power-on/off other equipment. The analog input of the system can be used to input signals such as pressure and
temperature. The system provides an RTU function for flow measurement.
RS-232 ( cable length 0 ~ 15m ) or RS-485 ( cable length 0 ~ 1000m ) can be directly used for data transmission
links for a short distance. Current loop can be used in medium or long distance transmission.
When the flowmeter is used in a network environment, various operations can be performed by a host device,
except for programming of the address identification code, which needs to be done via the flowmeter keyboard.
The command answer mode is used in data transmission, i.e. the host device issues commands and the flowmeter
answers correspondingly.
Common/special flow / thermal data monitoring system developed by our company can be used for flow data
collection. Based on characteristics of the flowmeter, the system makes full use of software and hardware designs
with flowmeter features. The system is simple, clear, economical, and reliable in operation.
Attention
In the communication protocol used functions, RS232 and RS485 serial communications can
not be used at the same time.

11.3 Direct connection via RS232 to the host device
See the below list of flowmeter serial port definitions.
11.4 Communications protocol and the use
The flowmeter meter supports these three communication protocols: FUJI Protocol, MODBUS-C Protocol,
MODBUS-I Protocol.
11.4.1 FUJI Protocol
Choose "0.FUJI" in Menu 96 for FUJI Protocol.
The communication protocol format used by the ultrasonic flowmeter is an expanded set of the Fuji FLV series
flowmeter protocol. The host device requests the flowmeter to answer by sending a "command". The baud rate of
asynchronous communication ( Primary station: computer system; Secondary station: ultrasonic flowmeter ) 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 the string of data is flexible. The order applies to both RS232 and
RS485. Frequently used commands are as follows:

2. "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. "s" expresses ON or OFF or UD. For example, "TR:ON, RL:ON" expresses that the OCT and relay are in
an actuated status; "TR:UD,RL:UD" expresses that the OCT and relay are not actuated.
5. "@" expresses the key value. For example, 30H expresses "0" key; Command "M4" is equivalent to
pressing the key "4".
6. "a" expresses the current value. The value range is 0-20. For example, AO2.34567 and AO0.2.
7. Eight "dddddddd" expresses the electronic serial number of the machine. "t" expresses the type of machine.
8. If there are multiple flowmeters in a data network then the basic commands cannot be used alone. The
prefix W must be added. Otherwise, multiple flowmeters will answer simultaneously, which will cause
chaos in the system.
1.Function prefix and function sign
1)
Prefix P
The character P can be added before every basic command. It means that the transferred data has CRC verification.
The method of counting the 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 relative binary 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 sum character, 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 W
Usage of prefix W: W+ numeric string address code +basic command. Value range of the numeric string is 0 ~
65535, except 13 ( 0DH carriage return ), 10 ( 0AH line feed ), 42 (2AH *) and 38 ( 26H & ). If the instantaneous
velocity of No. 12345 flowmeter is to be accessed, the command W12345DV( CR ) can be issued. Corresponding
binary code is 57H, 31H, 32H, 33H, 34H, 3 5H, 44H, 56H and 0DH.
3)
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. 4321 flowmeter is
requested to simultaneously return: 1] instantaneous flow, 2] instantaneous flow velocity, 3] positive total flow, 4]
energy total, 5] AI1 analogous input current value, the following command is issued:
W4321PDQD & PDV&PDI + &PDIE&PBA1 ( CR )
Simultaneously returned data are likely as follows:
+0.000000E+00m3/d!AC(CR)
+0.000000E+00m/s!88(CR)
+1234567E+0m3 !F7(CR)
+0.000000E+0GJ!DA(CR)
+7.838879E+00mA!59(CR)
2.Key Code
In a network environment, a key code is used to simulate the use of keys at the host device.
For example, the instruction "M1" is input through the serial port, which is equivalent to pressing Key 1 on the
keyboard of the ultrasonic flowmeter. Codes:

11.4.2 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) which is gained by the cyclic redundancy algorithm method.
MODBUS-I RTU mode uses hexadecimals to transmit data.

CRC ( Verify )
The range of flow meter addresses 1 to 247 (Hexadecimal: 0x01 ~ 0xF7 ), and can be checked in the Menu 46.
For example, decimal number "11" displayed on Menu 46 means the address of the flow meter in the MODBUS
protocol is 0x0B.
The CRC Verify Code adopts CRC-16-IBM (polynomial is X16+X15+X2+1, shield character is 0xA001) which is
gained by the cyclic redundancy algorithm method. Low byte of the verify code is at the beginning while the high
byte is at the end.
For example, to read the address 1 (0x01) in the RTU mode, if the instantaneous flow rate uses hour as a unit
(m3/h), namely reads 40005 and 40006 registers data, the read command is as follows:
