An Ultrasonic water level measurement system based on GPS is presented. According to the ultrasonic principle and GPS positioning technology, the secondary ultrasonic reflection in the air and the time spent in the liquid are measured to calculate the height of the water level and the depth of the liquid. The temperature compensation circuit is designed to improve the measurement precision. The use of GPS, the specific location of measurement points can be got, and the key position multi-point level measurement, cycle monitoring, real-time monitoring and mobile monitoring can be achieved
