🧪 What is a Positive Displacement Flow Meter?
A Positive Displacement (PD) Flow Meter is a volumetric flow meter that directly measures the amount of liquid passing through. It uses mechanical components such as oval gears or rotary pistons that rotate as liquid flows, capturing a known volume per rotation.
Unlike other types of flow meters, PD meters excel in:
-
High accuracy (up to ±0.5%)
-
Low flow applications
-
Handling viscous and abrasive fluids
