Description

Устр011ства дл  измерени  расхода жидкостей по изменению температуры нагретого электрическим током ироводши-са, охлаждаелюго движущейс  жидкостью, известны. В таких устройствах прпмеиеиы два электрических термометра сопротивлени , включенных в различные ветви электрического моста и иомещеиных внутри трубопровода-один в иотэке, а другой в неподвижной жидкости, заключенно в ответвлении трубопровода. Такие устройства пепрнгодны дл  измерени  расхода агрессивных жидкостей, быстро разрушающих погруженные в них нагретые проводники:.The means for measuring the flow rate of liquids by the temperature variation of a conductor heated by an electric current, a coolant moving fluid, are known. In such devices, two electrical resistance thermometers, included in the various branches of the electrical bridge and in-room inside the pipeline — one in the iotec and the other in a stationary liquid, are enclosed in a branch of the pipeline. Such devices are suitable for measuring the flow rate of aggressive liquids that quickly destroy heated conductors immersed in them :.

В предлагаемом устройстве этот иодостаток устранен тем, что в случае измерени  расхода агрессивных жидкостей термометры сопротивлепп  заключены в герметически закрытые чехлы из материала, нровод щего тепло.In the proposed device, this iodus is eliminated by the fact that in the case of measuring the flow rate of aggressive liquids, the resistance-resistance thermometers are enclosed in hermetically sealed covers made of a material that conducts heat.

На чертеже пзображена схема устройства.In the drawing, a schematic of the device is shown.

Устройство содержит одинаковые термометры 1 и 2 сопротпвленпл. Термометры наход тс  под некоторым иocтo нны папр жеипем тока питатги  (наиример, 60 в).The device contains the same thermometers 1 and 2 resistively. Thermometers are under some of the current parameters of the current of the power supply (naimer, 60).

Дл  предохрапепи  от разрушаюп его действи  актпвных жидкостей термометры иомещены в герметически закрытые чехлы Я и 4 из материала, ировод.чидего тепло. Одпи пз термометров (тот, который в чехле 3) помещен внутри трубопровода 5 в токе пзмер емо) жидкости, протекающей в направленип стрелки А, а термометр 2 (в чехле 4) иомещеп в пеподвижпой жидкости ответвлени  трубопровода 6.In order to protect themselves from the destruction of its action of actinous liquids, thermometers are placed in hermetically sealed covers I and 4 of a material that conducts heat. One thermometer (the one in the case 3) is placed inside the pipeline 5 in the current of measurement) of the fluid flowing in the direction of arrow A, and the thermometer 2 (in the case 4) is placed in the fluid of the branch pipe 6.

Оба термометра включены в различные ветпп электрического моста 7, в дпагоиаль которого включены иульгалькапометр 8 или, при необходимости б.локпровки, логометр 9.Both thermometers are included in various VetpPs of the electric bridge 7, the dapagial of which includes an ulkalkapometr 8 or, if necessary, blocking, a logometer 9.

Действие устройства основано на том, что охлаждение термометра 1 roiriiOTjTr.rreiiirsr. включетгиого в тгеш, посто нного папр гкепи.  10, пропорционально скорости прохождени  жидкости в т 1убопроводе и ое температуре.

Includes a permanent, permanent paprke. 10 is proportional to the rate at which the fluid passes through the tube and is at a temperature. For combining temperature variations of a flowing liquid, a second thermometer of the same type 2 is used in a stationary liquid.
