Abstract

The invention relates to a rotary flow meter for measuring gas flow, comprising a pair of three-toothed rotors, each of which has the shape of a double helical gear, wherein the first rotor is a mirror reflection of the second rotor, and the rotors are adapted to rotate in opposite directions; moreover, the flow meter comprises a body sealing the rotors adapted to form temporary measurement chambers having a strictly defined volume, formed between the outer surfaces of the rotors and the inner surface of the body. The rotary flow meter according to the invention is characterised by the rotors adapted not to contact each other and which are synchronised via an external module synchronising the rotation of the rotors.
