Faced with 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 pumping test in a 640-meter deep well. Its sensor uses a fully sealed stainless steel welding process, with a protection level of IP68, capable of long-term resistance to 85℃ liquid environments. At the same time, it integrates digital temperature compensation technology to ensure the accuracy of the 15.2℃ water temperature data.

In the recently completed 640-meter deep well monitoring project, the WH311 groundwater level automatic monitoring instrument demonstrated its intelligent control capabilities. The device has built-in high and low water level alarm functions. When the water level is abnormal, it automatically triggers the pump stop protection to prevent the deep well pump from running dry. Combined with the wireless transmission module, alarm information can be pushed in real time to the manager's mobile terminal.
