Abstract
A fluid volumetric flowmeter has a wall plate forming a chamber and a fluid inlet, and a fluid outlet. Two rotors positioned within the chamber have intermeshing lobes and valleys for turning in the chamber as fluid flows from the inlet through the chamber to the outlet. An indicator housing is connected to the chamber. A response shaft is rotationally mounted in the housing, and an encoder disk rotates with the shaft. A first coupling is mounted on the rotor. A second coupling is mounted on the shaft for rotating the second coupling, the shaft, and the encoder disk in response to rotation of the rotors.
