FIELD: physics.
SUBSTANCE: counter for water accounting comprises impeller with two magnets and temperature detector installed inside body with inlet and outlet nozzles, detector of magnetic field, unit of signal generation from temperature detector, timer, unit of control and calculation on the base of microcontroller, memory register for storage of measured total amount of hot water, memory register for storage of measured summary amount of water with temperature below 40 degrees Celsius accounted as cold water, liquid-crystal indicator for display of hot and cold water flow in mass units, switch of liquid-crystal indicator for possibility to separately read the readings.
EFFECT: higher accuracy of measurement due to accounting of dependence on temperature of magnetic field detector actuation frequency recount into liquid flow, increased validity of settlement between consumer and producing organisation.
