1, there are some interference factors near the instrument, such as motor and frequency conversion.
2. There is something wrong with the line;
3. It may be that the grounding is loose;
4. The air traffic control alarm is not set.
Electromagnetic flowmeter fluctuates greatly under normal working conditions, and the main reasons may be as follows:
1, wrong installation location. Not satisfied with the pipeline, or there is gas in the pipeline system, or bubbles are inhaled; Installed on vertical pipes, there may be reasons such as venting.
2. If the liquid contains evenly distributed fine bubbles, it will not affect the normal measurement, but if the measured volume flow is the sum of liquid and gas, the output signal will fluctuate due to the increase of bubbles.
3. The medium fluctuates or pulsates.
4. The electrode is polluted, or the electrode suitable for the measured liquid is not selected correctly.
In order to play its efficient and accurate measurement role, electromagnetic flowmeter needs to pay attention to instrument maintenance and check its working condition regularly. Find a way to solve the problem in time, so as not to cause greater losses.
