Electromagnetic flowmeter is a relatively common measuring instrument, and the problem of display jitter may affect the measurement accuracy.
1. Reasons for display jumping
1. Power supply problem: Electromagnetic flowmeter requires a stable power supply. If the power supply is unstable or the contact is poor, the display will easily jump.
2. Pipeline fluid problems: If there are large particles or gas, foam, etc. in the fluid in the pipeline, it may affect the measurement results of the electromagnetic flowmeter and cause the display to jump.
3. Problems with the electromagnetic flowmeter itself: If there is a problem with the internal components of the electromagnetic flowmeter or the electromagnetic field coil is in poor contact, the measurement signal will be unstable and the display will jump.
2. Solution
1. Check the power supply: Check whether the power supply is stable and whether there are problems such as poor contact. If there are problems, they need to be dealt with in time.
2. Clean the inside of the pipeline: Clean the large particles, gas, foam and other problems inside the pipeline to ensure that the fluid can flow normally, thereby avoiding the impact on the electromagnetic flowmeter.
3. Maintain the electromagnetic flowmeter: Maintain and maintain the electromagnetic flowmeter regularly, check whether the internal components are normal and whether the electromagnetic field coil is in good contact.
4. Replace the device: If none of the above methods solve the problem, the electromagnetic flowmeter may need to be replaced.
3. Summary
Electromagnetic flowmeter is a relatively common measuring instrument, and the problem of display jitter may affect the measurement accuracy. Therefore, when using an electromagnetic flowmeter, it is necessary to ensure stable power supply, clean the inside of the pipeline, and perform regular maintenance in order to better use the electromagnetic flowmeter.
