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.
