Potential Flux Monitor (PFM)

A watt-hour meter with an open or modified potential element costs your utility precious revenue. And unfortunately, a malfunctioning watt-hour meter is often undetectable in normal meter-reading procedures.

The hand-held, battery-powered Potential Flux Monitor (PFM) is a simple, instantly effective solution. The PFM provides simple test measures and displays the strength of the flux field induced by the voltage that's present in the potential elements of a meter. Remarkably, the device senses the flux field outside a meter cover in the proximity of each potential coil.

Test results can be easily interpreted by technical or non-technical personnel with minimal training. Find just one altered or failed meter and the PFM can pay for itself.
