FLUID-FLOW COUNTER Russian patent published in 1995 - IPC

FIELD: measuring equipment. SUBSTANCE: fluid, which flows through a housing, sets in rotation a turbine which is mounted on the axle in bearings. The turbine opens one of the openings resulting in pressure drop in a chamber and rotation of a plate about an axle. The plate made of magnet material changes magnetic resistance in a coil having the magnet. The number of pulses at the output is proportional to the fluid volume flowing through the counter. The number of pulses is counted by a pulse counter. EFFECT: enhanced reliability. 2 cl, 3 dwg
