Supplier Positive Displacement (PD) Flow Meter

WWW.DISTRIBUTORALATINDUSTRI.COM | Supplier Positive Displacement (PD) Flow Meter A Positive Displacement (PD) Flow Meter is a high-accuracy volumetric flow meter designed to directly measure the volume of petroleum products by trapping and transferring a fixed quantity of liquid through a precision measuring chamber. Each rotation or cycle represents a known volume, providing highly accurate and repeatable flow measurement regardless of changes in viscosity or flow profile. PD flow meters are widely used for custody transfer, fuel loading/unloading, tanker trucks, loading terminals, depots, refineries, and fuel distribution systems
