Positive Displacement (PD) Meters
Positive Displacement (PD) flow meters are volumetric flow measurement instruments ideal for low flow rates, highly viscous fluids, and measurement of flows involving starts and stops or pulsing. Positive displacement flow meters are similar in design to the gear pump. The principle of operation is reversed however; instead of the gears driving the fluid, the fluid drives the gears. A non-intrusive hall-effect sensor detects the movement of the gear and as each gear tooth passes the sensor, a ...show more -
