Electromagnetic flow meter is a commonly used flow measurement instrument, widely used in chemical, petroleum, pharmaceutical, food and other industrial fields. Although the electromagnetic flow meter is relatively reliable during use, some failures may still occur. The following are some common electromagnetic flow meter faults and their solutions.

1. The output signal of the electromagnetic flow meter is unstable

There are many reasons why the output signal of the electromagnetic flow meter is unstable. It may be caused by loose circuits of the electromagnetic flow meter, damaged sensors, magnetic field interference, etc. The way to solve this problem is to first check whether the line is normal. If the line is normal, you need to check whether the sensor is damaged. If the sensor is damaged, it needs to be replaced with a new one. In addition, it is also necessary to check whether there is magnetic field interference around the electromagnetic flow meter. If there is magnetic field interference, corresponding measures need to be taken.

2. The displayed value of the electromagnetic flow meter does not match the actual value

The reason why the displayed value of the electromagnetic flow meter does not match the actual value may be caused by a malfunction of the internal sensor of the electromagnetic flow meter, excessive liquid temperature, or excessive gas content in the liquid. The way to solve this problem is to first check whether the internal sensor of the electromagnetic flow meter is working normally. If the sensor fails, it needs to be replaced with a new one. In addition, it is necessary to check whether the liquid temperature and gas content are normal. If not, corresponding measures need to be taken.

3. The electromagnetic flow meter display cannot display

The reason why the electromagnetic flow meter display cannot display may be caused by power failure, display circuit failure, etc. The way to solve this problem is to first check whether the power supply is normal. If the power supply is normal, you need to check whether the monitor circuit is damaged. If the wiring is damaged, it will need to be replaced with a new one.

4. Magnetic field interference of electromagnetic flow meter

When an electromagnetic flow meter is interfered by a magnetic field, the measurement may be inaccurate or completely impossible. The way to solve this problem is to reduce the magnetic field interference around the electromagnetic flow meter as much as possible. Measures such as installing a magnetic shield around the electromagnetic flow meter and changing the installation position of the electromagnetic flow meter can be taken.

Another big problem is that the resistance of the inlet and outlet pipelines of the electromagnetic flow meter is unbalanced.

When the resistance of the inlet and outlet pipelines of the electromagnetic flow meter is unbalanced, it will affect the measurement accuracy and stability of the electromagnetic flow meter, and may even lead to measurement results with large errors. The main cause of this failure is unreasonable design or improper installation of the inlet and outlet pipelines, resulting in unbalanced pipeline resistance.

The methods to solve this problem mainly include the following aspects:

A. Adjust the pipeline layout: When the resistance of the inlet and outlet pipelines is unbalanced, the problem can be solved by adjusting the pipeline layout. For example, add or remove some elbows or straight pipes in the inlet and outlet pipelines, and adjust the length and diameter of the pipelines to balance the pipeline resistance.

B Add a pressure regulating device: In order to balance the resistance of the inlet and outlet pipelines, a pressure regulating device can be added to the pipeline. The pressure regulating device can balance the pipeline resistance by adjusting the flow rate at the inlet and outlet, thereby improving the measurement accuracy and stability of the electromagnetic flow meter.

C. Replace a suitable electromagnetic flow meter: In some cases, even adjusting the pipeline layout or adding a pressure regulating device cannot solve the problem of unbalanced resistance. At this time, it is necessary to replace the appropriate electromagnetic flow meter to adapt to the special situation of unbalanced pipeline resistance.

D. Clean the pipeline: Sometimes scale and dirt inside the pipeline can also cause imbalance in pipeline resistance, which in turn affects the measurement accuracy and stability of the electromagnetic flow meter. Therefore, the pipelines can be cleaned and maintained to keep them clean and smooth.

In general, the unbalanced resistance of the inlet and outlet pipes of an electromagnetic flow meter is a common fault. However, by adjusting the pipeline layout, adding a pressure regulating device, replacing a suitable electromagnetic flow meter, and cleaning the pipelines, the problem can be effectively solved and the measurement accuracy and stability of the electromagnetic flow meter can be improved.

Therefore, after-sales service is particularly important here. After-sales service is one of the important indicators to measure a company's comprehensive strength and brand image, because it is not only directly related to customer satisfaction and loyalty, but also related to the company's reputation and market position. For high-precision and high-stability equipment such as electromagnetic flow meter, after-sales service is even more important. Because it is inevitable to encounter some faults and problems during use. Without timely and professional after-sales service support, it will not only affect the normal production and economic benefits of customers, but also have a negative impact on the corporate image.
