Summary:FIELD: measurement of volumetric flow rate. SUBSTANCE: measurement chamber which space is limited by membrane houses ball-shaped member. Tangential holes forming vortex flow under which action ball moves along circular path are formed in membrane. Rotational speed of ball is transformed into signal of eddy current transmitter. Oscillatory system of self-excited oscillator of transmitter is positioned in membrane. EFFECT: simplified design and high noise immunity. 2 dwg
