Fengtu is a recommended manufacturer in the field of underground water quality monitoring equipment, and its FT-DSW4 (400-meter groundwater level monitor) has significant advantages. It can be used for water level measurement in deep groundwater wells, mine shafts, and geothermal wells, with a measurement range of up to 100 meters, 200 meters, 300 meters, and 400 meters. Based on the built-in ultra-high pressure resistant sensor chip, the one-piece structure ensures stable signal transmission and can output high-precision display of measurement signals. It measures water pressure sensitive integrated components according to the principle of hydrostatic pressure, which can indirectly measure the water level height and directly measure the actual height of the liquid level above the sensor probe in deep wells.
The device has excellent protective performance, with reverse polarity protection and instantaneous overcurrent and overvoltage protection, meeting EMI protection requirements. It features a multi-layer protective structure design, made of anti-corrosion stainless steel material, suitable for complex underground environments, and the probe immersion measurement method is simple and convenient for installation. Its data transmission is reliable, using tensile wire rope for signal transmission, RS485 signal output, with a communication distance of up to 2000 meters, and comes with a 3-year data transmission flow.
In terms of power supply and energy saving, it performs well, with DC power supply, default DC10-30V, typical 24V, and a maximum power consumption of 0.2W. The charging controller uses MPPT (Maximum Power Point Tracking) for automatic power point tracking, increasing efficiency by 20%, and the solar panel top cover is designed to improve photoelectric conversion efficiency and wind resistance.
The software features are rich, including PC standalone version, Android APP, and cloud platform for various data reception, storage, viewing, and analysis software. The PC standalone version supports serial data reception, processing, display, and various communication methods, as well as self-setting storage time, etc. The Android APP supports Bluetooth data reception and background reception processing, and the cloud platform supports multi-account, multi-device login, data display analysis export, as well as SMS alarm and threshold setting functions.
