Decreased electromagnetic flowmeter readings may be due to poor wiring, magnetic field interference, clogged pipes, or aging equipment.
1. Problem background
Electromagnetic flowmeter is a commonly used flow meter and is widely used in measuring liquid flow. However, sometimes there is a problem that the electromagnetic flowmeter reading keeps declining, affecting its accuracy and reliability, which needs to be investigated and solved in time.
2. Cause of the problem
The reason why the electromagnetic flowmeter keeps falling down may be due to the following aspects:
1. Poor wiring: inside the electromagnetic flowmeter There are many cables connected to the circuit board, and poor wiring can cause inaccurate readings.
2. Magnetic field interference: When the electromagnetic flowmeter is interfered by a strong magnetic field or other electrical signals, it will cause inaccurate readings.
3. Pipe blockage: If there are foreign objects or other substances blocking the pipe, it will affect the flow meter reading.
4. Equipment aging: As the use time increases, the sensors and circuit boards in the electromagnetic flowmeter may suffer from aging and damage, resulting in inaccurate readings.
3. Troubleshooting methods
To address the causes of the above problems, the following troubleshooting methods can be adopted:
1. Check whether the wiring is in good condition, especially the cable heads and terminal blocks. Are they in firm contact?
2. Place the electromagnetic flowmeter away from magnetic fields or other interference sources to avoid external interference.
3. Clean any foreign objects or other substances that may be present in the pipeline.
4. Maintain and inspect the electromagnetic flowmeter, and replace aging or damaged parts.
IV. Solutions
Based on the above troubleshooting methods, the following solutions can be taken:
1. Ensure good wiring to ensure that the internal circuit of the electromagnetic flowmeter is well connected.
2. Place the electromagnetic flowmeter away from magnetic fields or other interference sources
3. Regularly clean out foreign objects or other substances that may be present in the pipeline, and maintain the pipeline.
4. Regularly maintain and inspect equipment to ensure its normal operation and performance.
