摘要

本文介绍了一种测量和保持水箱恒定水位的装置。该设备使用容量传感器来测量水位。传感器的直流电压输出与水箱内的水位成正比。此电压也可用于其他自动化。水位，以百分比，显示在一个vu表与8个led。用于保持恒定电平的电路由一个带滞后的比较器组成。水位是可调的，使用电位器的参考电压(以百分比标记)。水位与规定的水位进行比较，两者之间的差异命令水泵的启动/停止，水泵通过继电器向水箱供电。设备由220V供电，与环境隔离。

Measuring and Maintaining the Water Level in a Tank for Efficient Use in Irrigation

This paper presents a device for measuring and maintaining the constant water level in a tank. The device uses a capacity sensor to measure the water level. The sensor has a DC voltage output proportional to the water level in the tank. This voltage can be used in other automation too. The water level, in percentages, is displayed on a vu meter with 8 LEDs. The circuit for maintaining the constant level consists in a comparator with hysteresis. The level of the water is adjustable, using a reference voltage from a potentiometer (marked in percentages). The level of the water is compared with the prescribed level and the difference between them commands the start/stop of the water pump which supplies the tank through a relay. The device is powered by 220V and is isolated from the environment.
