水塔与蓄水池水位的自动控制

Automatic Control of Water Level in Mater Tower and Resrvoir

水位的自动控制是供水系统中的一个重要环节,但因选择的控制线路不当,故障多,而达不到控制的目的.本文介绍了一种使用工频低电压的晶体管开关电路和技术参数的计算方法,经实践证明该电路工作可靠,实用性强.

Automatic control of water lcvel plays an important role in water providing system.Any incorrect selection in control circuit will cause failurein water level control.This paper has introduced the application of industrial-trequency low voltage transistor switch circuit and the calculating method of it's technical data.It is proved that the circuit works reliably and has a high utilily.
