This high-performance portable ultrasonic depth meter features auto-range tracking for real-time, accurate, and stable depth readings in the field. Its multi-parameter display simultaneously shows water depth, water temperature, date, time, sound velocity, and battery status — giving you a complete picture of your measurement environment at a glance. Powered by a built-in 7.4V lithium battery with a runtime exceeding 12 hours, it's engineered to keep up with demanding outdoor and long-duration survey work. Whether you're conducting hydrological monitoring, underwater topography mapping, or reservoir bathymetry, this depth sounder delivers the reliability professionals depend on.

Precision Display & Real-Time Multi-Parameter Monitoring

Compact Design, Versatile Data Output & Adaptive Performance
In hydropower systems, the depth sounder precisely measures the water level and depth of reservoirs and dams to ensure safe operation. It rapidly maps seabed or lakebed topography for resource development and engineering planning. Determining exact depths enables accurate positioning of water sampling points at different layers. In river surveys, a depth sounder provides real-time depth profiles for analyzing channel changes and supporting flood control, navigation, and ecological protection.

Q1: What is the maximum measurement range of this portable ultrasonic depth meter?
A1: This depth sounder offers four selectable ranges: 100m, 150m, 200m, and 300m, all tested under standard conditions (20°C, still water surface). Users can switch between ranges based on site requirements, making it suitable for shallow river surveys as well as deeper reservoir or lake bathymetry.
Q2: Can this depth meter be used in both seawater and freshwater?
A2: Yes. The instrument supports both seawater and freshwater measurement environments. The working frequency (50–2000 kHz) and sensor draft depth (0.000–9.999mm) are both adjustable, allowing the device to be optimized for different water types, salinity levels, and acoustic conditions.
Q3: How is the measurement data stored and exported?
A3: All readings are automatically saved to the built-in 16MB memory, with capacity for up to 10,000 historical records. Data can be downloaded to an SD card and exported as TXT files for further analysis and reporting.
Tips: How to get the most out of your portable ultrasonic depth meter?
For best accuracy in field surveys, ensure the sensor is fully submerged and positioned perpendicular to the water surface before taking readings. In environments with significant water flow, turbulence, or suspended sediment, adjusting the working frequency downward (toward 50 kHz) can improve signal penetration and reading stability. Always allow the device a brief warm-up period after powering on in cold conditions (approaching 0°C) to ensure consistent performance throughout your survey session.
