Positive Displacement Flowmeters

Positive Displacement Flowmeters

Positive Displacement (PD) Flowmeters, are volumetric flow meters which employ one of the oldest-known techniques for measuring flow, are widely used in industry, and have one of the largest install bases of any liquid flow meter technology. Positive Displacement Flowmeters feature two precisely machined rotating members inside a measuring chamber of known volume which may be used to accurately determine the rates at which the volumes of liquid are passing through the chamber as a function of the rotors’ velocity. A more detailed discussion of the principle of operation can be found in our article about the positive displacement measuring principle.  SmartmeasurementTM offers a variety of PD meters with our ALPD series.
