Abstract
Изобретение относитс к приборостроению и предназначено дл измерени расхода газов и жидкостей с разной входной температурой, потока. Целью изобретени . вл етс повышение точности измерени и обеспечение эксплуатационной надежности . Перед началом измерени производ т прогрев картера 1 включением в сеть нагревател 5. При движении среды по проточным каналам 2 среда нагреваетс и возникает градиент температур входного и выходного потоков. Этот градиент фиксируетс измерительными элементами 3 с сопротивлени ми Ri, R2 и Нз посредством совместного включени с логометром, угол поворота магнитного пол которого пропорционален измер емому расходу. Увеличение или уменьшение температуры измер емого потока на входе в картер не вносит погрешности в измерение, поскольку не вли ет на величину Дф 2 ил.The invention relates to instrument engineering and is intended to measure the flow of gases and liquids with different inlet temperatures. The purpose of the invention. is to improve measurement accuracy and ensure operational reliability. Before the measurement starts, the crankcase 1 is heated by switching on the heater 5 into the network. As the medium moves through the flow channels 2, the medium heats up and a temperature gradient of the input and output flows occurs. This gradient is fixed by measuring elements 3 with resistances Ri, R2 and Hz by means of joint switching on with a logometer, the angle of rotation of which the magnetic field is proportional to the measured flow. An increase or decrease in the temperature of the measured flow at the entrance to the crankcase does not introduce an error in the measurement, since it does not affect the value of Df 2 sludge.
