Features & Benefits
Pulse Output Device (POD)
General Information
The Liquid Controls Pulse Output Device (POD)
converts the rotary motion of Liquid Controls
Positive Displacement Flowmeters into electronic
pulses that equal the volumetric measurements of
the meter.
The POD mounts directly to the front cover of the
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.
