The Solution to the Unstable Electromagnetic Flowmeter Posted by : admin / Posted on : Apr 09， 2020

Check the unstable flow of the zero-point electromagnetic flowmeter. According to the process, first consider the preliminary logging and judgment, and then carefully check and try to remove the defects one by one. The order of the inspection items listed in the process is the one that can be inspected or interrogated and understands that no major operation is required, that is, it is easy to follow, and it is difficult to follow the past on-site maintenance experience. Check the requests you need. If it is confirmed by the preliminary logging that it is the cause of the last few problems, a detailed inspection can also be conducted early. The pipeline is not filled with liquid or the liquid contains air bubbles. Objectively, there is no activity in the flow sensor and there is a small amount of activity in practice. The main reason for this type of problem is that the pipeline's shut-off valve is poorly sealed, and the small leakage amount detected by the electromagnetic flowmeter is misunderstood as a zero point change.
