Description
функцию по защите импульсной трубки от пр мого попадани жидкости в ее полость при гидравлических ударах.the function of protecting the impulse tube from direct liquid entry into its cavity during water hammer.
Рассто ние между отборниками давлени 4, или база измерени м выбранатаким образом, что максимально исключено вли ние сжимаемости воздуха на точность определени .The distance between pressure taps 4, or the measurement base, is chosen in such a way that the influence of air compressibility on the accuracy of determination is excluded to the maximum.
Сигнал с дифференциального манометра 7 фильтруетс от высокочастотных колебаний в демпфирующем устройстве 8. В сумматоре 10 происходит вычитание сигнала , пропорционального плотности жидкости и сигнала заданного нижнего значени диапазона контрол плотности жидкости, поступающего от корректора нул 9.The signal from the differential pressure gauge 7 is filtered from high-frequency oscillations in the damping device 8. In the adder 10, the signal is proportional to the density of the liquid and the signal of the predetermined lower value of the range for controlling the density of the liquid from the zero corrector 9.
Таким образом, измен сигнал с выхода корректора нул можно измен ть точку начала отсчета диапазона контрол плотности жидкости, а использование воздушных камер в отборниках давлени позволит увеличить срок безаварийной службы устройства контрол плотности жидкости. Применение микропроцессорной техники позвол ет с большой точностью обрабатывать и. контролировать сигнал значени плотности жидкости.Thus, by changing the signal from the output of the zero corrector, it is possible to change the starting point of the range for controlling the density of the liquid, and the use of air chambers in the pressure tracers will increase the life of the trouble-free operation of the device for controlling the density of liquids. The use of microprocessor technology allows to process and with great accuracy. monitor the signal of the fluid density value.
