Flow Measurement

Positive Displacement Flow Meter

PD meter (Mechanical and Digital Display)

PD meter positive displacement meter bi rotators mechanical counter digital display


The measuring chamber of the iSOLV PD Meter bi-rotator positive displacement flow meter consists of a body, a pair of rotor gear and a top cover. It is designed for demanding applications in liquid flow measurements that require high accuracy and reliability. PD meter has a pair of uniquely designed rotators that eliminate or reduce pulsations in the flow.
