Positive displacement (PD) flow meters measure the volumetric flow rate of a moving fluid or gas by dividing the media into fixed, metered volumes (finite increments or volumes of the fluid).

A positive displacement (PD) flow meter is a type of flow meter that provides high accuracy (±0.1% of actual flow rate in some cases) and good repeatability (as high as 0.05% of reading).

The patented Flow Technology DC-F Sanitary Series positive displacement flow meter (PD meter) is made for liquid flow applications in the food, dairy, and pharmaceutical industries. The design is ideal for accurately measuring thick fluids in applications where batch repeatability is desired.

Positive displacement (PD) flow meters measure the volumetric flow rate of a moving fluid or gas by dividing the media into fixed, metered volumes (finite increments or volumes of the fluid).

Brodie International offers a wide array of industry leading positive displacement measurement solutions. Our portfolio includes meters ranging from 1/2” to 16” in size, capable of measuring flows from 0.9 GPM to 13,000 BPH (2.7 LPM to 2,000 M3/HR).

Tek-Trol's Positive Displacement Meter solutions offer precision in fluid measurement, ensuring accurate and reliable results in industrial and commercial applications, and enhancing process efficiency.

PD flow meters are precision instruments whose internal moving components are hydraulically locked in tandem with the volume of fluid moving through the flow meter. The meters can measure intermittent flows, very low flow rates, and liquids of almost any viscosity. When fluid flows, PD meters instantly move.

Positive displacement (PD) meters are time tested and proven across the world. They are extremely dependable mechanical meters with known results and a metrology that makes over registration an impossibility.

A 'PD' or positive displacement flow meter measures the fluid in discrete volumes. The fluid flows into a chamber, is sealed off once the chamber is full and produces either an electronic pulse or a drives a gear to register the volume as it exits the chamber.

A positive displacement meter is a mechanical equipment which quantifies the flow directly, by dividing the liquid flow current through its flow chamber into known volumetric segments, attaining to count the volume displaced by the gear train in each of the rotors of the meter.
