Abstract
Изобретение относитс к измерительной технике и может быть использовано при измерении расходов жидкости. В измерительном участке трубопровода вдоль его оси размещена пластина 1 с закрепленными на ней термобатаре ми 2, 3, 4. Тепловыдел ющие спаи термобатарей расположены по одну сторону пластины, теплопоглощающие - по другую. При подаче напр жени на центральную термобатарею 3 происходит выделение тепла на одной стороне термобатареи и поглощение на другой. При движении жидкости по вл етс разностный сигнал, пропорциональный разности температур на термобатаре х (термопреобразовател х) 2 и 4 с точностью в два раза большей за счет одновременного использовани при измерении эффектов охлаждени и нагрева жидкости на обеих сторонах пластины. 2 ил.The invention relates to a measurement technique and can be used to measure fluid flow rates. In the measuring section of the pipeline along its axis there is a plate 1 with thermometers 2, 3, 4 fixed on it. The heat release junctions of the thermopile are located on one side of the plate, the heat absorbing ones on the other. When applying voltage to the central thermopile 3, heat is generated on one side of the thermopile and absorbed on the other. As the fluid moves, a differential signal appears that is proportional to the temperature difference across the thermopile x (thermocouples) 2 and 4 with an accuracy of two times due to the simultaneous use in measuring the effects of cooling and heating of the fluid on both sides of the plate. 2 Il.
