FAQ

1.Q:Ultrasonic flowmeter reading unstable change drastic?
A: Retrofit the flow sensor away from the source of oscillation or move it upstream of the device that is changing the flow pattern.
2.Q:Ultrasonic flowmeter reading is not accurate, the error is large?
A:Install a sensor at a place far away from the device. The upstream distance of the sensor is 30D and the downstream distance is 10D.
3.Q:Ultrasonic flowmeter sensor is good, but the flow rate is low or no flow rate because of what?
A:1 Because the paint and rust outside the pipeline have not been removed. The sensillum. 2. The pipe surface is uneven or the ultrasonic flowmeter equipment is at the welding joint. 3, the measured medium is pure or solid suspended matter is too low.
4.Q:When the control valve is somewhat closed or the flow rate drops, the reading will increase.
A: The sensor is installed too close to the flow of the control valve, and when some closed valves are closed, the practice of flowmeter measurement is to control the flow rate of the valve to improve the flow rate, and the flow rate is increased because the diameter is reduced.
5.Q:After the ultrasonic flowmeter probe is used for a period of time, there will be an irregular alarm. Especially if there are more impurities in the conveying medium, this kind of problem will be more common
A:Solution: Clean the probe regularly (once a year is recommended).
6.Q:When the ultrasonic flow meter's conveying medium contains liquid impurities such as water, the pressure tube of the flow meter is easy to produce liquid accumulation, and when the temperature is low, the pressure tube will freeze, especially in the northern winter.
A:Solution: Purge or energize pressure tube heat tracing.
7.Q:Does the instantaneous flow fluctuate greatly?The signal intensity is high and the measured flow body fluctuates greatly.
A:Solution: Adjust the position of the probe, improve the signal strength, and ensure the stability of the signal strength. If the fluid fluctuates a lot, the position is not good
