G01F3/06 - CPC Classification

Classification description:

Measuring the volume flow of fluids or fluent solid material wherein the fluid passes through the meter in successive and more or less isolated quantities, the meter being driven by the flow with measuring chambers which expand or contract during measurement having rigid movable walls comprising members rotating in a fluid-tight or substantially fluid-tight manner in a housing
