Cox Instruments Series PA-422, Turbine Meter Preamplifier Explosion-proof Housing 4-20 mA Two-wire System (power supplied over signal wire)

COX Series PA-422 Turbine Meter Analog Preamplifiers provide a 4-20 mA output signal proportional to the process flow rate to allow for interface with data acquisition devices. The 4 mA and 20 mA end points are field-scalable. An optional flow meter mounting kit allows for swivel adjustment to align to conduit. Remote meter mounting is available.
