ELECTRONIC TACHOMETRIC METER FOR ACCOUNTING OF LIQUID AND GAS FLOW WITH REMOTE TRANSMISSION OF MEASUREMENT RESULTS VIA RADIO CHANNEL Russian patent published in 2019 - IPC G01F1/75 

FIELD: measuring equipment.

SUBSTANCE: this technical solution, in general, relates to the field of measurement equipment, and in particular to measuring instruments for determining the speed of the primary sensitive element rotating under the action of flowing water flow. Electronic tachometric counter for metering of liquid flow, made with possibility of transmitting measurement results on communication module, comprising housing with inlet and outlet branch pipes, in which there are primary sensitive element installed on axis in cavity of housing and made with possibility of rotation under action of flowing water flow; electronic counting mechanism, which is located under the cover of the upper and on the base, made with possibility of measuring rotation of the primary sensitive element in both directions by means of two Hall sensors; liquid crystal display arranged on the electronic counting mechanism and under the upper cover, configured to display the measured volume of the liquid volume determined by the electronic counting mechanism; power supply located on electronic counting mechanism; two measuring transducers of magnetic field, outputs of which are connected to two separate inputs of analog-digital converter of electronic counting mechanism, made with possibility of detecting rotation of primary sensitive element in two directions and located on lower part of electronic counting mechanism; a communication module located on the electronic counting mechanism and configured to transmit data on liquid consumption to the receiving device.

EFFECT: high accuracy of measuring the speed of the primary sensitive element of the counter, measuring volume of spilled water in both directions with reduced power consumption and broader functional capabilities of the counter.
