    Compact Design, Versatile Data Output & Adaptive Performance

    • This ultrasonic water depth meter packs a 5-button operation for convenient and quick control, and the built-in 16MB memory is capable of storing up to 10,000 historical records. Data can be exported directly to an SD card as TXT files.
    • Output interfaces include serial USB, 4–20mA, and 0–5V, ensuring compatibility with a wide range of data acquisition systems. 
    • The depth sounder supports both seawater and freshwater environments, making it suitable for coastal surveys, inland river monitoring, and reservoir depth measurement alike. 
    • The blind zone auto-adjusts to ≤ 0.5m, minimizing near-surface measurement error. The working frequency is fully adjustable from 50 to 2000 kHz.

    Applications

    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.

    FAQs

    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.

    Using this ultrasonic portable depth sounder has significantly improved my efficiency.
    After receiving it, I tested it on a water bucket at my office (filled with water to a depth of approximately 0.8 meters). After turning it on and placing the probe vertically in the water, the display took about 1-2 seconds to display the value, which matched the actual measurement with a ruler by only about 1 centimeter, which is pretty consistent. I then went to the site to measure five rainwater wells (ranging in depth from 2.3 to 4.1 meters). The operation was quite simple: I turned on the power, waited for the probe to acclimate to the water temperature (the manual recommends letting it sit for 10 seconds), then placed the probe vertically against the well wall and slowly lowered it into the water. The display quickly stabilized. The measurement error for most wells was within ±2 centimeters. The deepest well, at 4.1 meters, displayed a value of 4.08 meters, which was consistent with the tape measure's result of 4.1 meters.
