GAS FLOW METER WITH TRANSFORMATION OF STREAM OSCILLATION TO ELECTRONIC SIGNAL Russian patent published in 2007 - IPC G01F1/20 G01F15/18 

FIELD: tool-making industry, possible use in system for feeding breathing gas onboard an aircraft.

SUBSTANCE: flow meter contains body with input and output connections, inside of which generator of oscillations is positioned with jet discontinuous elements. From outside the body is covered with cover, inside which electronic board with elements of electronic circuit is located. Jet generator is made in form of stapled round plates, equipped with appropriate slits and flow dividers, which are combined into a whole by screws. Mounted on generator is container with piezo-sensor, equipped with rubber linings. Body of measuring device is suspended on two cable shock absorbers of oval shape and two C-shaped cable shock absorbers positioned inside them. Cables of shock absorbers are fastened to metallic piece positioned on the body and placed inside rubber lining. Dressing of ends of all cables is performed using rubber bushings and shock-absorbing washers.

EFFECT: ensured given measurement precision due to minimized influence of external interference (vibration and acoustic noise).
