Positive Displacement
Instrument used to measure the volumetric flow rate of a liquid or gas by trapping a fixed, known volume of fluid inside closed chambers and then counting the number of times the volume is filled and emptied.
These devices are exceptionally accurate and excel at measuring high-viscosity fluids like oils, fuels, and syrups, where higher viscosities actually minimize internal slippage to improve precision. Additionally, because they operate independently of flow profiles, they do not require straight upstream pipe runs and are widely favored for high-precision industrial custody transfer applications.
Direct Volumetric Measurement
Measures flow by continuously trapping discrete, fixed volumes of fluid in moving chambers (such as gears or pistons) and counting the cycles, independent of velocity, density, or turbulence.
High Pressure Performance
Suitable for high-pressure pumping applications.
