How to deal with negative values ​​displayed by intelligent electromagnetic flowmeters

Case introduction

Intelligent electromagnetic flowmeter is an intelligent flowmeter developed using advanced technology. It is very different from old-fashioned analog or non-intelligent electromagnetic flowmeters, especially in terms of measurement accuracy, reliability, stability, and usage functions. and service life, etc.

1. The sensor signal line is connected reversely. Since the electromagnetic flowmeter has forward and reverse flow measurement functions, it displays reverse flow.

Treatment method: Replace the signal line.

2. The sensor is not installed according to the flow direction mark, causing the measurement direction to be opposite.

3. The electromagnetic flowmeter measuring pipe is empty or not full, and there is gas. At this time, the flow meter will display a negative number or the flow value will fluctuate from high to low.

Processing method: Fill the pipe with the medium to be measured so that the flow meter can meet the measurement conditions.
