Abstract
A fluid volumetric flowmeter has a casing forming a chamber, a fluid inlet, and a fluid outlet communicating with the chamber. 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. At least one of the rotors has a facial recess for receiving a magnet. A shaft mount is connected to a wall of the casing. A response shaft is rotationally mounted in the shaft mount. An indicator connected to the shaft rotates with the shaft. A first magnetic coupling is mounted in the rotor recess of the rotor. A second magnetic coupling is mounted on the shaft near the first magnetic coupling for rotating the second magnetic coupling, the shaft, and the indicator in response to rotation of the rotors.
