Positive Displacement


Positive displacement flow measurement technology accurately measures the volume of liquid passing through the flow meter. This technology works by directing the fluid to mechanically displace components within the meter to measure its flow as discreet parcel volumes. Prior calibration and sound engineering tolerances ensure superior accuracy and repeatability from many styles and variations of PD meter.

Oval gear flow meters, nutating disc flow meters and oscillating piston are all examples of meter types that use positive displacement in order to accurately measure flow. Positive displacement flow meters are especially good for smaller line sizes, low flow rates, high viscosity and will last a very long time in service, especially on lubricating and well filtered liquids.
