Water Level Meter, specifically a type used for measuring water levels in wells, boreholes, or other water bodies.
It features a reel-mounted, PVDF-coated engineer's tape with graduations (in this case, metric, showing numbers like 10, 20, 30, etc.).
The probe at the end of the tape activates an audible signal and/or visible light when it contacts water, indicating the water level.
The device is commonly used in applications like deep well water level measurement, water conservancy projects, and environmental protection.
These meters are available in various lengths (e.g., 100M, 200M, 300M) and materials, with features like adjustable sensitivity and field
