Meter Type
Positive Displacement (PD) Flowmeter designed to measure the flow of most fluids including high and varying viscosities without requiring recalibration.

How It Works
Positive Displacement Flowmeters measure the volumetric flow of fluids in pipes. As fluid flows through the chamber the oval gears rotate. Each rotation corresponds with a fixed volume of fluid that is picked up by a sensor creating a pulse signal. Electronic displays convert the pulse signal to a flow rate or totals.
