Electromagnetic flowmeter flow deviation causes and solutions

Case introduction

1. Reasons for the large flow rate of the electromagnetic flowmeter

1. Measurement of medium density changes: Electromagnetic flowmeters usually measure based on the law of electromagnetic induction, so they are more sensitive to changes in the density of the measurement medium. If the density of the medium changes, it may cause the flow rate of the electromagnetic flowmeter to be too large. This situation usually occurs when the working conditions change greatly, such as large temperature fluctuations, changes in the gas content of the medium, etc.

2. Electromagnetic flowmeter sensor failure: The electromagnetic flowmeter sensor is the core component for measuring flow. If it fails, such as wear, damage, etc., it will cause the measured flow to be too large.

3. Abnormal power supply of electromagnetic flowmeter: Abnormal power supply of electromagnetic flowmeter may also be one of the reasons for high flow rate. Generally speaking, the abnormality of the electromagnetic flowmeter power supply is that the meter display is abnormal or too large. At this time, it is necessary to check whether the power supply is stable and other issues.

2. Solutions to the high flow rate of the electromagnetic flowmeter

1. Check the medium density: If the flow rate of the electromagnetic flowmeter is found to be too high, you need to check it first Whether the density of the measured medium changes. If so, the parameters need to be adjusted in time to restore normal measurement.

2. Check the sensor: If the electromagnetic flowmeter sensor fails, its reliability must be ensured, the parameters must be recalibrated or the sensor must be replaced.

3. Check the power supply: If the power supply of the electromagnetic flowmeter is abnormal, you should first check whether the power supply is stable. If it is unstable, deal with it in time.

4. Maintenance: In order to ensure the normal operation of the electromagnetic flowmeter, it should be inspected and maintained regularly, such as cleaning the sensor, checking the interface, etc.

In short, although the problem of excessive flow rate of electromagnetic flowmeter is not very common, once it occurs, troubleshooting and processing must be carried out in time to avoid adverse effects on industrial production. I hope this article can provide some practical reference for readers.
