Got a call out to a frack truck filling facility. Only one of 6 fairly new mag meters were working properly. One had a burnt card, two had RS-485 failure, and two were reading only half the flow. The two reading half flow is what I am wondering about. This is reused fracking water after going through weir tanks. It was suggested to me that the electrodes in the meters might be sludged up, giving a false reading. I'll try to contact the manufacturer tomorrow for recommendations.

Anybody seen this sort of problem with mag meters? These are Isoil brand.
