Cox Instruments Series PA-112, Turbine Meter Preamplifier Explosion-proof Housing 10V p-p Pulse, 3-wire System

COX Series PA-112 Turbine Meter Preamplifiers are used for long distance signal transmission and noise interference elimination. Their output signal frequency is proportional to the process flow rate. Meter or remote mounted units are available. An optional flow meter mounting kit allows for swivel adjustment to align to conduit. Remote meter mounting is available.
