VORTEX ACOUSTIC FLOWMETER Russian patent published in 2018 - IPC G01F1/32 

FIELD: measuring equipment.

SUBSTANCE: invention relates to a measuring technique, and more particularly to a vortex flowmeter designed to measure the flow and quantity of liquids and gases flowing in pipelines and can be used to control, regulate and account for fluid flows. Vortex acoustic flowmeter contains a measuring tube located in the branch pipe across the flow body, a radiator and receiver of ultrasonic vibrations, an ultrasonic frequency signal generator, three frequency dividers into two, two divisors of frequency with a variable coefficient of division, three amplifier-shaper, inverter, two phase detectors, two high-pass filters, low-pass filter, peak detector, two analog-to-digital converters, a multiplexer with two inputs, a microcontroller, an output device.

EFFECT: expansion of the range of permissible phase shift values, increasing the accuracy of measurements during operation over a wide range of temperatures of the controlled medium.
