Interference problems with electromagnetic flowmeters during welding operations
Thread Content
Our workshop uses some electromagnetic flowmeters, which are used in key parts such as the measurement of reaction proportions. The accuracy of flow monitoring is very high. When there is welding work in other places, it has serious interference with the flow meter, causing its measurement to be inaccurate. Now that welding is being done in a very far place (about two hundred meters away), the flow display will also fluctuate. I would like to ask if any of my colleagues have had the same situation happen to me, and are there any good solutions?
Our unit also has some electromagnetic flowmeters, and no such problems have occurred. I think there is something wrong with the shielding of your flow meter. If it is like you said, who would dare to use it?
What precautions need to be taken when shielding electromagnetic flowmeters? Is this the scope of the instrument profession?
