Class G01F : MEASURING VOLUME, VOLUME FLOW, MASS FLOW, OR LIQUID LEVEL; METERING BY VOLUME
Subclass 1/28: Measuring the volume flow or mass flow of fluid or fluent solid material wherein the fluid passes through the meter in a continuous flow (measuring a proportion of the volume flow G01F 5/00 ) by using mechanical effects by detection of dynamic effects of the fluid flow by drag-force, e.g. vane type or impact flowmeter
