Oscillating Piston
Brand: Niagara MetersPrinciple of Operation:
Liquid enters a precision-machined chamber containing an oscillating (rotating) piston.
The position of the piston divides the chamber into compartments containing an exact volume.
Liquid pressure drives the piston to oscillate and rotate its center hub.
The movements of the hub are sensed through the meter cover by a follower magnet.
Each revolution of the piston hub is equivalent to a fixed volume of fluid, which is indicated as flow by a register/totalizer.
Close clearances between the piston and the chamber ensure minimum liquid slip for highly accurate and repeatable measurement of each volume cycle.
