FLOWMETER Russian patent published in 2001 - IPC

Abstract RU 2161779 C1

FIELD: instrument engineering. SUBSTANCE: flowmeter is designed to measure flow rate in large-diameter pipelines (more than 200 mm). Flowmeter includes two waveguide resonators positioned in different sections along pipeline from its external side. Each resonator is made sectional. It contains K three-arm circulators and waveguides with elastic end walls (membranes) common with pipeline. Differential pressure coupled functionally with flow rate is determined by difference of inherent frequencies of resonators. EFFECT: higher sensitivity. 5 dwg
