DEVICE FOR MEASURING GAS FLOW RATE Russian patent published in 2017 - IPC G01F3/22 

FIELD: gas industry.

SUBSTANCE: invention relates to domestic appliances for measuring consumption of gas and vapors of liquefied gas. Electronic unit is equipped with a comparator, providing automatic determination of level of excess of gas flow rate sensor signal, and a current level shaper, providing a lower level of the input signal at the input of the micro-consuming AC voltage amplifier. Current level shaper is connected to the micro-consuming micro-controller for its additional power supply. Electronic unit is equipped with an infrared pulsed emitter, providing connection to a personal computer, or is additionally equipped with a network interface for integration into an automated system of commercial metering of gas consumption.

EFFECT: technical result is to provide the protection of the electronic unit from instantaneous pulse interference (overvoltage) due to redistribution of energy of gas flow sensor with simultaneous reduction of the capacity of the used battery and increase of its service life.
