Series PDM Flowmeter
Overview
Series PDM Flowmeters provide high levels of
accuracy and repeatability for a wide range of
liquids from low viscosity Solvents and
chemicals to viscous oils, greases and food
bases. Low pressure drop allows for economical
pump selection or gravity flow applications.

Series PDM Flowmeter
Principle of Operation
The Series PDM Flowmeter uses the oscillating
piston principle where the passage of liquid
causes a piston to oscillate smoothly in a
circular motion within the measuring chamber.
Each piston cycle passes a known volume of liquid
from the inlet to the outlet port, magnets in the
piston activate the reed switch and the solid
state sensor to provide pulse outputs for remote
flow, measurement and process control.

Principle of Operation
The diagram below shows the transition of fluid
from the Inlet Port through the measuring chamber
and then out the Outlet Port.

Series PDM Flowmeter
Outputs

• Reed Switch Output - Provides a voltage free
  contact closure. The reed switch is classed as a
  "simple device" and can be used in hazardous
  areas when connected via an approved
  intrinsically safe barrier.
• Square Wave Output - An open collector pulse
  output produced by a solid state Hall effect
  device. This 3-wire device requires 5-24 vdc
  excitation voltage and produces a high resolution
  square wave output.
