Pulse Output Device (POD)

The Pulse Output Device (POD) converts the rotary motion of Liquid Controls flowmeters into a high resolution, unscaled pulse stream that equal the volumetric measurements of the meter.

The Pulse Output Device mounts directly to the front cover of the flow meter in place of the packing gland. The motion of the meter’s blocking rotor is magnetically coupled through a stainless steel wall to the electronics compartment of the POD. This eliminates the dynamic seal of the packing gland and isolates the electronics from the process fluid in the meter.

The electronic pulses generated by the POD is easily adapted to a wide variety of electronic monitoring devices and control equipment including the Truck III and Vega T electronic registers.
