Ultrasonic wave has many advantages in water-level monitoring, such as good orientation, energy concentration, strong reflecting ability etc. A water-level monitoring system was designed by using RS-485 and singlechip AT89C52. The system was composed of ultrasonic wave sensor, water-level measure module and host processing module. The results showed that the relative error of the system was less than 1%, with features of high accuracy, high speed of measurement, display visual, cheap and easy to operate.
