Description
Известные расходомеры, измер ющие массу протекающей жидкости, чувствительны к изменению не только илотности жидкости, ио и .4кости ее, приборы непригодны дл измерени быстропеременных процессов.The known flow meters, which measure the mass of the flowing fluid, are sensitive to changes in not only the liquid density, but also its measurement, and the instruments are unsuitable for measuring rapidly varying processes.
Предлагаемый прибор лищен этих недостатков и отличаетс тем, что может быть применен дл измерени массового расхода потока, а также как измеритель плотности жидкости в потоке. Это достигаетс тем, что чувствительный элемент, имеющийс в приборе, выполнен в виде колеблющегос в контролируемой среде тела и соверщает колебани , перпендикул рные направлению потока, а индуктивный датчик, усилитель и электромагнитный возбудитель прибора, включенные последовательно, образуют охваченную обратной св зью колебательную систему, по частоте колебаний которой суд т о плотности жидкости в потоке.The proposed device lacks these disadvantages and is different in that it can be used to measure the mass flow rate of a stream, as well as as a density meter for a liquid in a stream. This is achieved by the fact that the sensitive element present in the device is made in the form of an oscillating body in a controlled environment and oscillates perpendicular to the direction of flow, and the inductive sensor, amplifier and electromagnetic driver of the device, connected in series, form an oscillatory system covered by the feedback the frequency of oscillations which judged the density of the fluid in the stream.
На фит. I схематически показана конструкци прибора; па фиг. 2-схема включени прибора в режиме измерител плотности.On the fit. I schematically shows the structure of the device; pas figs. 2 is a circuit for switching on the instrument in the density meter mode.
Через трубопровод / проходит ноток н идкости. Наход ща с в трубе пластинка 2 совершает колебани , перпендикул рные направлению потока. Эти колебани возбуждаютс приводом, состо щим из т ги 3, пропущенной через сильфои 4, магнита 5 и катушки 6, в которую пропускают переменный ток. Съем сигнала осуществл етс магнитоэлектрическим датчиком, состо щим из магнита 7 и катущки 5.Through the pipeline / passes notes n liquids. The plate 2 in the tube oscillates perpendicular to the direction of flow. These vibrations are driven by a drive consisting of a pull 3, passed through sylphs 4, a magnet 5 and a coil 6, into which an alternating current is passed. The signal is removed by a magnetoelectric sensor consisting of a magnet 7 and a coil 5.
Система представл ет собой усилитель с положительной электромеханической обратной св зью, благодар которой пластинка совершает автоколебани . Обратна св зь осуществл етс электромагнитным возбудителем и датчиком. Выход датчика 9 и 10 соедин етс со входом усилител //, а выход усилител со входом 12 и 13 катушки 6 возбудител . Таким образом, получаетс система, аналогична камертонному генератору электрических колебаний. С точек 14 и 15 сиимаютс генерируеThe system is an amplifier with positive electromechanical feedback, due to which the plate performs self-oscillations. Feedback is carried out by an electromagnetic exciter and a sensor. The output of sensor 9 and 10 is connected to the input of the amplifier //, and the output of the amplifier with input 12 and 13 of the coil 6 of the exciter. Thus, a system is obtained that is similar to a tuning fork electric oscillation generator. From points 14 and 15, generations are generated.
