在工业生产中,水箱的用途十分广泛。在许多生产设备上,水箱液位的测量和控制与工艺生产过程的正常运行有着直接的联系。目前,测量和控制水箱液位的方法有不少,各有所长。我们知道,在开口容器上,用导压管将普通压力表和被测容器底侧连接以后,当容器中的液位发生变化时,相应比例的压力变化通过导压管引入到灵敏度较高的压力表中,这时压力表指示的压力与被测液位之间表现为如下关系:H=P/y
In industrial production, water tanks are used for a wide range of purposes. In many production facilities, the measurement and control of the tank level is directly linked to the normal operation of the process. At present, there are many ways to measure and control the level of water tanks, each having its own advantages. We know that in the open container, the pressure gauge with a pressure gauge connected to the bottom side of the container under test, when the level of the container changes, the corresponding proportion of pressure changes through the guide tube into the higher sensitivity Pressure gauge, then the pressure gauge indicates the pressure level measured between the performance as follows: H = P / y
