Automatic groundwater level monitoring instrument

Application Overview   
        Groundwater level and temperature measurement is particularly important for the geotechnical exploration industry, groundwater exploration, and hot spring water temperature and level monitoring industries. China is rich in groundwater resources, and in many areas, groundwater is the main source of water for human production and life. This requires strengthening the monitoring of deep wells to guide the rational use of water by humans. Real-time monitoring of changes in the dynamic water level of deep wells is also beneficial for earthquake monitoring, providing big data support for geological and earthquake monitoring. The WH311 deep well water level meter is a low-power consumption, IP68 high protection level, wired communication, and multi-sensor acquisition monitoring device. Suitable for harsh monitoring environments, it can realize data acquisition, storage, alarm, and transmission of groundwater level pumping tests, dam health, water supply and drainage networks, etc., and is particularly suitable for deep well water level applications.

System Overview   
        The WH311 groundwater level meter relies on a deep well water level sensor probe and has the advantages of fast construction speed and real-time long-distance transmission. It integrates front-end detection and back-end real-time display to achieve groundwater level monitoring, monitoring groundwater level and temperature data. With a paperless recorder, it can record data in real time, generate various reports and curves, and provide customers with data analysis and decision-making basis. This system is an important means of understanding the changes in groundwater, understanding the groundwater exploitation status, and guiding the protection of groundwater resources.

I. Specific Requirements

       Unit: Guizhou Provincial Geological Bureau 111 Geological Team

       Operating environment: Yudongxia geothermal pumping test, deep well depth 1000 meters, water temperature below 90℃.   
       Monitoring requirements: Real-time display of deep well water level during pumping tests to provide a basis for calculating geothermal resource exploitation; automated monitoring, improving office efficiency, and reducing manpower input;   
                     Ensure data accuracy, timeliness, and effectiveness;   
                     Ensure long-term operation under 1000 meters of water and below 90℃.

II. Measurement and Analysis

       Due to the particularity of the measurement of deep well water level monitoring, non-contact methods such as radar level meters and ultrasonic level meters cannot effectively transmit signals, and magnetic flap and bubble type measurements have depth limitations.   
       Now the WH311 deep well probe uses a laser hydrostatic principle (laser calibration of zero point full scale), which greatly simplifies the measurement process and reduces the cost of on-site data acquisition. The WH311 is easy to install and only needs to fix the level probe 3-5 meters above the deep well pump when the deep well pump is lowered into the well. Suitable for deep well water level measurement and monitoring, solving the problem of difficult deep well water level measurement, with the following points to meet user needs:
