Description
трубок установлены на одном уровне, то давление воздуха при его выходе из этих трубок одинаково и не зависит от разности давлений, измер емых пьезометрическими трубками.Since the tubes are installed at the same level, the air pressure at its exit from these tubes is the same and does not depend on the pressure difference measured by piezometric tubes.
При одинаковом сопротивлении дросселирующих устройств 3 расходы воздуха через них равны вследствие равенства потерь давлени на каждом из них. Это равенство не нарушаетс при изменении разности давлений между пьезотрубками датчика. Поэтому потери давлени в импульсных лини х не завис т от величины измер емой плотности и не внос т погрешностей в измерени .With the same resistance of the throttling devices 3, the air flow through them is equal due to the equality of pressure losses on each of them. This equality is not violated by changing the pressure difference between the piezo tubes of the sensor. Therefore, the pressure loss in the impulse lines does not depend on the measured density and does not introduce errors to the measurements.
Предмет изобретени Subject invention
Пьезометрический плотномер жидкости, содержащий дифманометр, две пьезометрические трубки, импульсные трубки и дросселирующие устройства, отличающийс тем, что, с целью повышени точности определени плотности, в плотномер введен распределитель воздуха, выполненный в виде двух закрытых сообщающихс сосудов, в каждом из которых конец импульсной трубки опущен в жидкость, а входные трубки дифманаметра расположены выще уровн жидкости.A piezometric fluid density meter containing a differential pressure meter, two piezometric tubes, pulse tubes and throttling devices, characterized in that, in order to improve the accuracy of density determination, an air distributor is inserted into the density meter, made in the form of two closed communicating vessels lowered into the liquid, and the input tubes of the difmanmeter are located above the liquid level.
