Portable Water Depth Sounder: Ultrasonic Technology for Depth Measurement in Rivers, Lakes, and Reservoirs

The portable water depth sounder utilizes ultrasonic technology to measure water depth. With a measurement range of 0 to 150 meters, it is effective in both still water and flowing water with velocities of up to 5 meters per second. The device features built-in data storage and export capabilities, making it well-suited for hydrological surveys, reservoir capacity calculations, and channel sounding.

This handheld ultrasonic depth sounder is designed for measuring water depths in reservoirs, lakes, rivers, and shallow coastal waters. It calculates depth automatically by leveraging the constant speed of sound in water and the time interval between the transmission and reception of ultrasonic signals. Developed based on years of R&D and manufacturing expertise, the device integrates the best features of similar products. Its ultrasonic transceiver circuitry incorporates specialized large-scale integrated circuits, with 99% of components utilizing surface-mount technology (SMT). The unit is designed for low power consumption, ensuring stable, long-term operation.

The device offers a measurement range of 0 to 150 meters with a 0.5-meter blind zone. It features 32 levels of adjustable transmission power, complemented by an automatic gain control (AGC) function. It provides a minimum display resolution of 0.1 mm, with a measurement accuracy of ±1% of the full range. A full-color Chinese-language LCD screen allows for the intuitive display of measurement results. Operating at frequencies between 200 and 2000 kHz, the device allows for on-site parameter adjustments via the main unit’s keypad; it comes factory-calibrated and also supports field calibration. An internal flash memory module automatically saves measurement data as Excel files, with a maximum capacity of 5,000 records. Data can also be exported via a USB flash drive for convenient post-processing and analysis.

Adaptable to a wide range of aquatic environments, this portable water depth sounder delivers stable measurements in still water and functions reliably in flowing water with velocities of up to 5 meters per second. It is easy to operate, lightweight, and offers rapid response times for efficient data collection. This equipment is primarily designed for underwater surveying applications, including topographic mapping of rivers and lakes, monitoring of river cross-sections, calculation of reservoir storage capacity, and channel surveying. It meets data acquisition requirements for tasks such as hydrological testing, inspection of hydropower reservoir areas, river channel surveying, and aquatic environmental monitoring, providing reliable baseline water-depth data for work in water conservancy, hydrology, and environmental monitoring.
