YANDDEA Well Water Depth Gauge, Water Level Meter Well Water Level Indicator Water Level Measurement with Fixed Probe and Steel Tape for Wells, Boreholes, Reservoirs and Pipes 100m(328ft)

✪【Electronic Water Level Gauge】The water level gauge is powered by a 9V battery, which is convenient for construction and portability, and saves the trouble of connecting another power cord. The reel is ergonomically designed for good balance and ease of use, with a stand-alone design, convenient carrying handle and an excellent brake. They are robust and smooth running. ✪【Measurement Specifications and Accuracy】 The well water level meter measures in centimeters, with a minimum reading of 1 mm and a repeatability of ≤ 2 mm. The probe has a depth range of 30 m/100 m, making it ideal for measuring well depth. The sensor at the probe tip provides stable measurement with virtually zero displacement. The probe features a larger 25 mm (0.99 in) diameter and is easily removable and cleanable. ✪【Operating Principles】: This portable water level gauge features a high-precision stainless steel probe for precise water depth measurement. When the probe enters the water, a circuit is closed, sending a signal to the reel, which emits a distinct beeping sound. Water level can then be determined by reading the tape directly from the well casing or borehole top. The instrument is suitable for temperatures ranging from -20°C to +60°C. ✪【Materials and Components】 The water level meter consists of four core components: a probe, a steel cable, a receiving system, and a reel. When the contacts touch the water surfaces, the receiving system activates; when the contacts leave the water surfaces, the receiving system automatically deactivates, ensuring long-term durability and waterproof performance. The tape seal plugs design allows the probe to be quickly and easily replaced if required. ✪【Applications and Precautions】 This water levels meter is widely used for measuring water levels in wells, boreholes, reservoirs, and water pipes. Suitable for the observation of groundwater level in hydro power projects and inspectors who inspect dam body infiltration line, it is an ideal tool for observing groundwater levels. Handle the probe with care and avoid bending the cable, especially near the probe, to ensure measurement accuracy and device life.
