достига  наибольшей скорости в меньшем Сечении, вследствие чего разрежение в данном сечении будет наибольшим. Так KiaK даайейие жидкости в емкости 7 равно атмосферному а по наименьшему сечению дроссел  10 меньше атмосферного, то при нормальиом уровне (Н) .жидкости в емкости 7 через полости корпуса I наД мембранами (А) и между мембранами (Б) будет циркулировать Жидкость от емкости 7 по трубопроводам 8, 12 и 9, 13 к дросселю 10. В этом случае толкатель 4 под действием веса жидкости в полост х А и Б корпуса I, преодолева  усилие пружины 5, займет нижнее положение, сигнализиру  о иормальном (Н) уровне жидкости. При уровне жидkocTH в емкости 7 меньше нормального (Н), но больше предельного (П) в полости А корпуса I будет циркулировать воздух, а в | 1олости Б - жидкость. Так как удельный вес воздуха ниже удельного веса жидкости. то в этом случае поло жение толкател  4 определитс  весом жидкости в полости Б и усиЛием ггружйиы 5, которому соответствует позици  «С переключател  9. При достижеНИН предельного уровн  (П) в емкости 7 в полост х А и Б клапана 1 будет циркулировать воздух, вследствие чего толкатель 4 под действием пружины 5 займет положение «П. Формула изобретени  Сигнализатор уровн  жидкости в емкости, соДержаший корпус, расположенные в нем две измерительные мембраны, образующие три полости и св занные обш,им штоком с преобразователем, выходного сигнала, и магистраль сжатого воздуха, отличающийс  тем, что, с целью усилени  чувствительности и повышени  надежности срабатывани , он снабжен установленным в магистрали сжатого воздуха дросселем переменного сечени , подключенного к газовому пространству емкости и наименьшее сечение которого соединено с полост ми над верхней мембраной и между мембранами, причем верхн   полость над мембраной соединена трубопроводом с емкостью иа нормальном уровне, полость между мембранами - с емкостью на предельном уровне жидкости, а нижн   полость соединена с атмосферой, Источники информации, прин тые во внимание при экспертизе: 1- Авторское свидетельство СССР № 226438, кл. G 01 F 23/16, 1966. achieve the highest speed in a smaller Section, as a result of which the vacuum in this section will be greatest. Since KiaK daayei liquid in the tank 7 is equal to the atmospheric and the smallest section of the throttles 10 is less than the atmospheric, then at normal level (N). The liquid in the tank 7 through the cavities of the body I on the membranes (A) and between the membranes (B) 7 through pipelines 8, 12 and 9, 13 to the throttle 10. In this case, the pusher 4 under the influence of the weight of the fluid in the cavities A and B of the housing I, overcoming the force of the spring 5, will take the lower position, signaling the normal (N) level of the fluid. When the level of liquid in the tank 7 is less than normal (H), but more than the limit (P) in the cavity A of housing I air will circulate, and in | 1 cavity B - liquid. Since the specific gravity of air is lower than the specific gravity of the fluid. In this case, the position of the pusher 4 will be determined by the weight of the fluid in cavity B and the force of Grigrujay 5, which corresponds to the position "C of the switch 9. When the level reaches the limit (P) in the tank 7 in the cavities A and B of valve 1, air will circulate what the pusher 4 under the action of the spring 5 will take the position "P. The claims of the liquid level indicator in the tank, holding the case, two measuring diaphragms located therein, forming three cavities and connected with the transducer, the stem with the converter, the output signal, and the compressed air line, in order to enhance the sensitivity and increase reliability of operation, it is equipped with a variable cross section throttle installed in the compressed air line connected to the gas space of the tank and the smallest section of which is connected to the cavities above the upper surface The membrane between the membranes is connected to the normal level, the cavity between the membranes is at the marginal level of the liquid, and the lower cavity is connected to the atmosphere.
