Portable Ultrasonic Water Depth Meter Utilizing Ultrasonic Technology for Water Depth Surveying in Rivers, Lakes, and Reservoirs

Portable Ultrasonic Water Depth Meter employs an ultrasonic measurement method with a range of 0 to 150 meters and a blind zone of 0.5 meters. It features automatic gain adjustment and a resolution of up to 0.1 millimeters. Capable of operating in both still water and flowing water with velocities of up to 5 meters per second, it is well-suited for hydrological surveying, river channel mapping, and aquatic environment monitoring.

Portable Ultrasonic Water Depth Meter is a portable, handheld ultrasonic depth-measuring instrument that determines water depth based on the principle of acoustic ranging. During operation, the ultrasonic transducer is positioned at a specific location on the water surface; the instrument then calculates the water depth by leveraging the constant propagation speed of sound in water and the time elapsed between signal transmission and reception. Developed based on years of manufacturing experience and incorporating the design strengths of similar devices, the instrument utilizes specialized large-scale integrated circuits for its ultrasonic transceiver circuitry—with a 99% surface-mount component (SMD) integration rate. It features an LCD screen for the intuitive display of measurement data. The circuit architecture ensures long-term, stable operation while maintaining low overall power consumption. The device is easy to operate and highly portable, offering rapid response times, stable and accurate results, and resilience against data deviations caused by basic water flow disturbances. Beyond static water bodies, it can effectively perform depth measurements in flowing water with velocities of up to 5 meters per second.

Portable Ultrasonic Water Depth Meter is suitable for a wide range of applications, including reservoir capacity calculation, river and lake topographic mapping, river cross-section profiling, channel surveying, and shallow-water point measurements. It also meets the requirements for water depth data acquisition in maritime operations, fisheries exploration, and underwater scientific research. With its compact structure and robust protection designed for outdoor field environments, the instrument is ideal for long-term use by hydrological stations, hydroelectric reservoir facilities, and environmental monitoring agencies. Compared to traditional depth-measurement methods, it reduces the need for manual labor and enhances the efficiency of aquatic surveying operations.
