Q2: The flowmeter is powered on, and there is a flow display when there is no water.

(1) When the meter is powered on, a small flow will appear, and the duration is about 15S ~ 30S. The flow value will fluctuate non-stop and may be positive or negative. This situation is normal and belongs to the self-test behavior when the flowmeter is turned on.

(2) When the pipe is empty, the flowmeter value keeps jumping. This situation is generally caused by the unreasonable setting of the empty pipe alarm threshold or the prohibition of the empty pipe alarm. It is necessary to reset the empty pipe alarm threshold according to the actual situation on site or turn on the empty pipe alarm function.

(3) The pipe is full, but the data of the flow meter jump consistently. If the jitter data is very small, you can solve the problem by cutting out small signals. If it is large, there is a problem with the customer's field-wiring generally, and it is necessary to re-check the wiring method of the signal line and the excitation line.
