HEAT AMOUNT DETERMINATION METHOD Russian patent published in 1995 - IPC

FIELD: heat amount counters. SUBSTANCE: simultaneously with liquid heat-carrier temperature and consumption measuring in direct and reverse pipeline they using thickness measuring device measure pipelines walls thickness to correct value of pipelines diameters in process of their walls overgrowing. Heat consumption measurement is exercised by frequency ultrasonic heat consumption meter with detachable piezoconverters on measuring signal frequency in range of 300 100 kHz. Required amount of heat is determined according to measured signals using counter-timer. EFFECT: increased accuracy of heat consumption measurements.
