How the Oscillating Piston Flow Meter works;

Liquid enters a precision-machined chamber containing an oscillating (rotating) piston within the flow meter. The position of the piston divides this chamber into compartments with a precise volume. The pressure from the liquid drives the piston to oscillate (rotate) its centre hub. The movements of the hub are sensed through the cover of the flow meter by a follower magnet. Each revolution of the piston hub is equivalent to a fixed volume of liquid, as indicated by a register or rate totaliser. Close clearances between the piston and the chamber ensure minimum liquid slip for highly accurate and repeatable measurement of each volume cycle making this a highly accurate and reliable flow meter.

Features and Benefits of an Oscillating Piston Flow Meter;

High degree of accuracy; ± 0.5% of rate

High Degree of repeatability; ± 0.1% of rate.

Cost effective;

Eliminates upstream and downstream straight run piping requirements.

Power is not required for the mechanical version.

Versatile design and construction; standard 316 SS/ETFE allows user flexibility with different fluids.

Common Applications for Oscillating Piston Flow Meters:

Acids

Solvents

Hydrogen Peroxide

Sodium Hydroxide

Distilled Water
