液位控制在水处理行业、化学工业、电厂中应用极广泛,尤其在水厂它的应用更为重要,如水塔上水的自动控制,高层建筑的自动上水等。当然该液位控制仪的测量功能也可测量矾池的液位,从而得知每班的矾消耗量,为企业的上等级作好计量基础工作,很显然它也同样适合测量水库的水位。图(一)是该液位仪测量液位方法的示意图。它通过浮球将液位高低的物理量转换成对应电压变化量。当液位上升时,浮球上升,重锤通过软索向下运动,电位器向逆时 Level control in the water treatment industry, chemical industry, power plants in a very wide range of applications, especially in the waterworks its application is more important, such as water tower automatic control of water, high-rise buildings, such as the water. Of course, the liquid level controller can also measure the measurement function of the liquid level of the alum pool, so that each class of alum consumption, for the enterprise to make the basis of the upper level measurement work, it is clear it is also suitable for measuring the reservoir water level. Figure (a) is a schematic diagram of the liquid level gauge method. It floats the physical level of liquid level into the corresponding voltage change amount. When the liquid level rises, the float rises, the weight moves downward through the soft cable, and the potentiometer moves counterclockwise
