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.

The WH311 incorporates a high-strength, high-pressure sensor chip. It calculates water level using the hydrostatic pressure principle (P=ρgh), with a measurement range of 0-1000 meters and a pressure resistance tested to 2000 meters of water pressure. The integrated stainless steel sealed structure ensures long-term stability79. Paired with the dedicated WH6 display recorder, it automatically records data at a frequency of 1 minute/time, supporting 365 days of continuous storage. The wireless transmission system transmits the signal remotely to a control center 5000 meters away, with an accuracy error of only 1cm.

China boasts abundant groundwater reserves, which serve as the primary source of water for production and daily life in many regions. However, due to China's large population, the significant spatiotemporal variations in water resources, coupled with extensive water wastage and pollution during actual usage, the usable amount of groundwater has drastically decreased, leading to various real-world problems such as land subsidence and lake drying. This necessitates enhanced groundwater monitoring to guide rational water use by humans.

Pumping Test for Gansu Institute of Hydrogeology and Engineering Geology
Currently, the WH311 deep well probe uses a laser static pressure principle (laser calibration zero point full scale), greatly simplifying the measurement process and reducing the cost of on-site data acquisition. The WH311 is easy to install; simply fix the level probe 3-5 meters above the deep well pump when lowering the pump into the well. Suitable for deep well water level measurement and monitoring, solving the problem of difficult deep well water level measurement.
