Electromagnetic flowmeter electrode dirty will have what effect

Case introduction

1. Impact

Dirty electromagnetic flowmeter electrodes will have an impact on flow measurement. When the electrode surface is contaminated, the electrode is in a non-ideal electrode state, so that a non-zero magnetic field will be generated on the electrode surface, thus affecting the accuracy of the measurement. In addition, dirty electrodes will also reduce the close contact between the electrode and the measurement medium (usually liquid or gas), affecting the stability and accuracy of the measurement results.

2. Cleaning method

In order to ensure the accuracy and normal measurement values ​​of the electromagnetic flowmeter, the electrodes need to be cleaned regularly. The following methods can usually be used to clean the electrode:

1. Use a foam sponge and clean water to gently wipe the surface of the electrode to remove dirt attached to the surface;

2. Use acid, Soak the electrode in alkaline solution or organic solvent to remove surface dirt, but be careful not to use excessive solution or soak for too long, otherwise it will cause damage to the electrode surface;

3. Frequent use of electromagnetic flow Use cleaning fluid to clean the electrode surface and keep the electrode surface clean;

4. Check and replace the electrode regularly.

3. Preventive measures

In addition to regular cleaning of the electrodes, the following preventive measures can also be taken:

1. When the electromagnetic flowmeter is installed in the pipeline When using, a filter should be installed in front of the flow meter to prevent solid impurities, tiny particles, etc. in the medium from contaminating the electrode surface;

2. During use, attention should be paid to maintaining the equipment, and regularly inspecting and replacing the electrodes;

3. Avoid using overly corrosive media during operation.

In summary, dirty electromagnetic flowmeter electrodes will have a great impact on flow measurement. In order to ensure the accuracy of measurement, it is necessary to pay attention to the maintenance and upkeep of the equipment in daily operations, and regularly inspect the electrodes. Perform cleaning. At the same time, pay attention to precautions during use to ensure good flow measurement results.
