Direct volume, no inference — for liquid measurement that has to add up.
A positive displacement meter measures liquid by repeatedly filling and emptying a known volume — direct measurement rather than inference from a differential. That makes PD meters a fit for viscous liquids and applications where totalized volume is the point.
Energy Flow supplies and calibrates positive displacement meters as part of the complete flow measurement line. Tell us the fluid, viscosity, flow range, and line size, and we will recommend and furnish the right meter.
Send line size, service conditions, and materials — if you'd like us to calculate the bore, just include your flow conditions.
