Ultrasonic Fish Finder Transducer Waterproof Sensor Water Depth Measuring

1. Introduction:

The working principle of the depth finder is to measure and calculate the depth of water by using ultrasonic wave to penetrate the medium and produce reflection on the surface of different medium, and by using ultrasonic transducer (probe) to transmit ultrasonic wave and to measure the time difference between the transmitting wave and echo wave.

2.Application:

● locating

● Approach measurement

● escaped obstruction

● fish finder
