Why does the electromagnetic flowmeter show a negative value?
The electromagnetic flowmeter is an intelligent flowmeter that can realize both positive and negative metering. The instantaneous flow shows that the positive and negative sides have nothing to do with some physical properties of the fluid, only related to the flow direction of the medium, if the electromagnetic flowmeter is installed or operated. The flow shows a negative value for several reasons:
1. The electromagnetic flowmeter sensor is not installed according to the flow direction indicator, resulting in the opposite measurement direction.
Treatment method: Reinstall the electromagnetic flowmeter according to the flow direction identification.
2. The sensor signal line is reversed. Since the electromagnetic flowmeter has a forward and reverse flow measurement function, the reverse flow is displayed.
Solution: Switch the sensor signal line to the correct connection.
3. The pipe is empty or not filled, and there is gas. At this time, the electromagnetic flowmeter will display negative or flow values.
Treatment method: Fill the pipeline with the measured medium, so that the electromagnetic flowmeter has the measurement conditions.
Remarks: At this stage, the electromagnetic flowmeter converter applicable to Bo Rui meter can directly set the forward or reverse metering in the internal parameter setting. Therefore, several solutions can not solve the negative value problem. Please contact Henan Bo. Rui Instrument Co., Ltd., the company will arrange relevant technical personnel to contact you.
