Abstract
The present invention relates to a positive displacement flow meter having a pair of rotors to be rotatably engaged with each other which are provided with tooth profile curves of a cycloid and of a trochoid. Since the tooth profile of one rotor is equal to that of the other rotor, transmission of energy between the two rotors is uniform, and wear of teeth of the two rotors being reduced.
