The WMP Series Mag-Flowmeter is a battery powered flowmeter that uses a magnetic field to measure flow very accurately with no moving parts. It’s unaffected by debris in the water and does not scale up or get plugged like traditional flowmeters. They work well installed between the pump and filter so you can measure flow even during a backwash. The WMP series comes with a threaded fitting kit, only 2 pipe diameters of straight pipe are required before the flowmeter for accurate measurement.
