Transducers Installation
Proper installation point is a key for transducer installation. Following factors must be
considered:
Full filled pipeline, shaking, steady flow, scaling, temperature, pressure, EMI, instrument well.
>> Full filled pipeline
Following situations can be full filled of liquid:
6.

>> Shaking
There cannot be obvious shaking on the installation point, otherwise it needs to be tightened.
>>Steady flow
Steady flow is helpful for ensuring measurement accuracy.
Standard requests for steady flow are:
1. The pipe should be far away from pump outlet and half- open valve. 10D to upstream and 50D to
downstream. (D means outer diameter)
2. 30D to pump outlet and half - open valve.
>> Scaling
The inside scaling would have bad effect on ultrasonic signal transmission, and would decrease
the inner diameter as well. As a result, the measurement accuracy can not be guaranteed.
Please try to avoid choosing the installation point with inside scaling.
>>Temperature
The liquid temperature on installation point should be in the working range of transducers.
Please try to choose the point with lower temperature. Avoid to choose points like the outlet of
boiler water and heat exchanger. Return water pipe would be better.
Temperature range of standard clamp on and insertion transducers: -30 ~ 90℃
Temperature range of high temperature clamp on and insertion transducers: -30 ~ 160℃

>>Pressure
The maximum press ure for standard insertion and inline transducer is 1.6MPa
Out of this range need customized.
>>EMI (electromagnetic interference)
The ultrasonic flow meter, transducer and signal cable can be easily interfered by interference
sources such as frequency changer, radio station, microwave station, GSM base station and
high-tension cable. Please try to avoid these interference sources when choosing installation
points.
The shield layer of flow meter, transducer and signal cable should be connected to earth.
Better to use isolated power supply. Do not use the same power supply with the frequency
converter.
>>Instrument well
When measuring underground pipes or need to protect the measuring points, an instrument
well is required. To ensure the enough installation space, the sizes of instrument well should meet
the following requirements.
7.2
Clamp on transducer Installation
Before installation, please verify the parameters of pipeline and liquid. To ensure the
installation accuracy.
1)
Installation procedure
Select an installation method → Input the measuring parameters → Clean pipe surface →
Install transducers → Check the installation
2)
Select an installation method
There are two different methods for clamp on transducers: V method and Z method.
>> V method
V method should be priority selected for pipe sizes DN15
-
DN200. Let the pair of
transducers horizontal alignment, the central line in parallel with the pipeline axis.

>> Z method
Z method should be priority selected for pipe sizes DN200
-
DN6000. Also can be used when V
method doesn’t work well. Make sure the vertical distance of two transducers equals to the
installation distance, and the two transducers are on the same axis surface.
3) Positioning installation points
>> V method
The line between two transducers is parallel to pipe axis, and equal to the distance shown in the
converter. As shown, A, B are the two installation points.
>> Z method
1 Firstly according to the installation distance shown in converter, positioning two points A, C on the
same side of pipeline. AC is parallel to pipe axis.
2 Perpendicular to the pipe axis, opposite to point C, get Point B.
3 Check. Measure the length between A and B from both sides of the pipe, get AB1 and AB 2. If
AB1 = AB2, then B is the correct point. If not, need to positioning point B and C again.
As shown, A, B are the two installation points.
Page 15

4) Clean the surface of installation points
Paint, rust and anticorrosive coating on installation points need to be cleaned. It’s good to use a
polishing machine to get the metal luster.
As shown below:
5) Install transducers
After transducer wiring and sealing, please evenly smear 2- 3mm couplant on the transducer
emitting surface. Then put the transducers on the installation points, fixed with
steel belt or steel
rope.
6) Check Installation
Please see details in Chapter 7.5
7.3 Insertion type transducer installation
! Before installation, please verify the parameters of pipeline and liquid. To ensure
the installation accuracy.
1) Installation procedure
Select an installation method → Input the measuring parameters → Positioning installation
points
→ Fix ball valve base → Open hole under pressure → Install transducers → Check the
installation
2) Select installation method and positioning installation points
Insertion type transducers are suitable for pipe sizes > 50mm.
Two different installation methods: V method and Z method. Generally use Z method, only
use V method for lack of space.
>> V method
V method can be used for DN50mm - 300mm. Let the pair of transducers horizontal
alignment, the central line in parallel with the pipeline axis, and the transmit direction mush
be opposite.
Page 16

>> Z method
Z method can be used for all pipes > DN50mm. Make sure the vertical distance of two
transducers equals to the installation distance, and the two transducers are on the same axis surface.
The transmit direction mush be opposite.
>> Parallel insertion
If there is insufficient installation space or the transducers can be only installed on the top of
pipeline, parallel insertion transducer will be a good choice. (Pipe size ≥ 300)
Positioning of parallel insertion transducer need to meet the 3 factors as follow:
· Installation distance = Vertical distance of two transducers along the pipe axis direction
· Make sure two transducers are in the same horizontal line,
Insertion depth = 1/3 inner diameter
· Users can set the distance between transducers by themselves. Recommend 300~500mm
Page 17

3)
Positioning installation points
>> V method
The line between two transducers is parallel to pipe axis, and equal to the distance
shown in the
converter. As shown, A, B are the two installation points.
>> Z method
1. Firstly according to the installation distance shown in converter, positioning two points A, C
on the same side of pipeline. AC is parallel to pipe axis.
2. Perpendicular to the pipe axis, opposite to point C, get Point B.
3. Check. Measure the length between A and B from both sides of the pipe, get AB1 and AB 2. If
AB1 = AB2, then B is the correct point. If not, need to positioning point B and C again.
As shown, A, B are the two installation points
4)
Fix ball valve base
>> Welding Fix
For carbon steel pipes, the ball valve base can be welded directly. Make sure that the
central point of ball valve base is overlapped with the transducer installation point.
Matters need attention:
· Please take the PTFE sealing gasket out from the base before welding.
· Please clean the pipe surface around welding point before welding. Pay
attention that there
should not be any
air hole during welding, which can avoid leaking. Welding
strength must
be ensured.
· Do not sputter welding slag on the base thread.
· Non-deformation of base during welding.
After welding, tighten ball valve into the base.
Page 18

>> Pipe hoop Fix
For pipes can’t be welded directly like cast iron pipe, cement pipe, copper pipe and
composite pipe, customized pipe hoop is recommended.
The hoop center should be overlapped with the transducer installation point. Please
compress the sealing gasket tightly to avoid leaking.
5) Open hole
After finishing the installation of ball valve and base, insert the open- hole tool into ball
valve and lock it. Then open the ball valve, start drilling, from slow to fast. Close ball
valve after drilling.
See more details in the video of insertion transducer installation.
6) Install transducer and adjustment
Adjust the proper insertion depth and transmit direction to get good ultrasound signal.
>> Insertion depth adjustment
Adjust the depth scale according to pipe wall thickness, and completely push in
thetransducer rod.
