WH311 Deep Well Monitoring System: High sealing and anti-interference design empowers complex hydrological environments
Facing challenges such as high pressure, corrosion, and signal attenuation in deep well monitoring, the WH311 groundwater level automatic monitoring instrument, with its technological advantages, became the core equipment for a 640-meter deep well pumping test. Its sensor uses a fully sealed stainless steel welding process, with a protection level of IP68, capable of withstanding 85℃ liquid environments for extended periods. It also integrates digital temperature compensation technology, ensuring the accuracy of 15.2℃ water temperature data.
The polyurethane steel wire cable equipped on the device not only has high tensile strength but also has a built-in air duct to balance the back pressure chamber pressure, avoiding measurement errors caused by temperature changes. In the pumping test, the WH311 transmits data in real time via a 4-20mA signal or RS485 communication, and cooperates with the WH6 recorder to automatically generate Excel tables and curve graphs, greatly improving data processing efficiency.
In addition, the device supports both 220VAC power supply and battery power supply modes, adapting to outdoor environments without power sources, and uses a triple lightning protection design to ensure stable operation in extreme weather.
