M29
Entry to setup empty signal threshold. When the signal is less than this threshold, the
pipe is regarded as empty pipe, and the flow meter will not totalize flow.
This is based on the fact that, for most occasions, when pipe is empty, the transducer
would still receive signal, just smaller than normal, As a result, The flow meter would
show normal operation, which is not correct.
Make sure that the entered value must be less than the normal signal strength.
When much noisy signals are received, to make sure the flow meter will not incorrectly
totalize flow, there is also a ‘Q’ threshold should be entered in M.5

7. Transducers Installation
7.1 Choose installation points
Proper installation point is a key for transducer installation. Following factors must be considered:
Following situations can be full filled of liquid:
Vertical upwardObliquely upwardLowest point
>> 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 5D to downstream. (D means outer diameter)
2. 30D to pump outlet and half-open valve.
>> Ultrasonic Flow meter User Manual
26
>> 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 pressure 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.
D means the pipe diameter

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:
Insertion depth = 1/3 inner diameter

Do not sputter welding slag on the base thread.
Non-deformation of base during welding.
5) Open hole
>> 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:
should not be any air hole during welding, which can avoid leaking. Welding strength must
be ensured.
After welding, tighten ball valve into the base.
>> 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.
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.

The flow meter includes the detection ability. M90 is used for checking signal strength and quality.
M91 is used for checking the ratio of measured and theoretical transmission time (transmission
time ratio).
M90 is used for checking the signal strength and signal quality(Q value) of upstream and
downstream transducers.
Signal strength is represented by numbers 00.0 ~ 99.9, 00.0 means no signal and 99.0 means
maximum signal. Generally, the flow meter can work properly when signal strength is > 60.0
Signal quality (Q value) is represented by numbers 00 ~ 99. 00 means signal is worst and 99
means signal is best. The flow meter can work properly when Q > 60.
During the installation, please adjust the transducer to make the signal strength and signal
quality the larger the better. This will ensure the flow meter long term stable operation and lead to
accurate measurement.
