4.4. Check proper installation
Signal strength, signal quality and the ratio of measured to theoretical transmission
time (referred to as transmission time ratio) are three important parameters used to
check whether the sensor is installed correctly. They are described below.
4.4.1. Signal strength and quality
The M90 windoFlow measurementw is used to display the upstream and
downstream signal strength and signal quality Q values detected by the flow meter.
Signal strength is expressed in numbers from 00.0 to 99.9.00.0 indicates no signal
received and 99.9 indicates maximum signal.Under normal working conditions, the
signal strength should be ≥60.0.
The signal quality Q value is expressed as a number from 00 to 99, with 00
representing the worst and 99 representing the best.The normal working condition
is the signal quality Q value >60.
When installing, please pay attention to the signal strength and quality, the better,
the signal strength and Q value is high, can ensure the flow meter measurement
results are more stable and accurate.

If the signal strength and Q value are too low, the following methods can be used to
improve the signal strength and Q value:
(1) If the measured flow value is unstable and the signal strength is lower than 70.0,
choose a better installation point again.
(2) Carefully grind the outer surface of the pipe until there is a metallic sheen,
adding a little more coupling agent.
(3) Slightly adjust the relative position or transmitting Angle of the sensor, observe
the received signal strength of the flowmeter at the same time, find the position of
