Positive Displacement Flow Measurement

Positive displacement (PD) volumetric flow rate measurement.

Positive displacement flow meters measure volumetric flow rate directly.

There are many different principles of design used for manufacturing positive displacement flow meter, which use different shaped chambers and moving parts to suit the intended application, but principally they are all producing a way of breaking up the flow into countable fixed dimension packets, using dynamic chambers as the flow passes through the PD flow meter.

The dynamic chambers have precise dimensions and therefore it is possible to precisely determine the amount of fluid transferred by each chamber. The number of chambers filled are counted over time, and thus the volumetric flow rate can be determined by multiplying the total number of counts by the volume of the chamber and dividing by the total time.
