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.
