FIELD: measurement technology.
SUBSTANCE: flowmeter-counter has casing made of part of pipe-line and jet self-excited oscillator provided with jet oscillation sensor mounted in by-pass channel. Through channel of pipe-line has converging member. Edge of converging member is faced to flow and has groove which forms through ring-shaped slit. Supply channel of jet self-excited oscillator opens to the ring-shaped slit. Output channel of self-excited oscillator is connected with narrow part of converging member. Depth of ring-shaped slit is equal or deeper than diameter of supply channel of jet self-excited oscillator. Area of ring-shaped slit equals or is bigger than cross-section area of supply nozzle of self-excited oscillator. Straight parts of paths ahead and behind the point where flowmeter-counter is installed are not necessary.
EFFECT: higher precision of measurement.
