The Dual-frequency Echo Sounder is a low cost ultrasonic water depth instrument meter, which is used for measuring water depth in silting or sedimentation studies, dredging surveys in lakes, rivers, ports, sea, and inshore hydrographic surveying. These are also applicable in testing aid for electronic servicing, research and development, education, etc. The instrument can be used as a conventional echo sounder with depth data output via an RS485 serial port, or 4~20mA output.

This Dual Frequency depth meter adopt the ultrasonic principle, have perfect function to measure the water depth, and control, data tranmit, communication. The Dual Frequency Level meter is sold as a customized products, we will supply the meter as .
