Positive Displacement Flow Meter: Working Principle, Types, and Applications Explained
1. Introduction Positive Displacement (PD) flow meters are among the most accurate types of flow measurement instruments available in the industry. Unlike other flow meters that infer flow rate based on velocity or differential pressure, PD meters measure the actual volume of the fluid passing through the meter. They operate by trapping fixed volumes of […]
