Water Well Level Sensor


The WH311 deep well level transmitter is specifically designed for deep well level measurement. Targeting deep wells with relatively large measurement ranges, its measurement range can reach 100 meters, 300 meters, or even 1000 meters. This is mainly based on the high-pressure, high-sealing sensor chip built into the WH311. The integral structure can withstand a 2000-meter water pressure waterproof test. Signal transmission uses a polyurethane anti-pulling steel wire cable to ensure that the signal is output and displayed in real-time with high accuracy and stability.

  • Application Overview  
            Groundwater level and temperature measurement is particularly important for the mining industry, groundwater exploration, and hot spring temperature and water 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 seismic industry monitoring. The WH311 deep well water level measuring instrument is an ultra-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 for underground wells, fire safety, dam health, water supply and drainage networks, etc., and is particularly suitable for underground well applications.


    System Overview  
            The WH311 groundwater level measuring instrument relies on a deep well water level sensor probe, has the advantages of fast construction speed and real-time long-distance transmission, integrates front-end detection and back-end real-time display, realizes groundwater level monitoring, can monitor groundwater level and temperature data, and the supporting paperless recorder can record data in real time, generate various reports and curves, providing data analysis and decision-making basis for customers.

    I. Specific Requirements

           Unit: Guizhou Provincial Geological Bureau 111 Geological Team

           Operating environment: Yudongxia geothermal water extraction test, deep well depth 1000 meters, water temperature within 90℃.  
           Monitoring requirements: Real-time display of deep well water level during the water extraction test to provide a basis for calculating geothermal resource exploitation; automated monitoring to improve office efficiency and reduce labor input;  
                           Ensure the accuracy, timeliness, and effectiveness of the data;  
                           Ensure long-term operation underwater at 1000 meters and below 90℃.

     

    II. Measurement and Analysis

           Due to the special nature 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 float and bubble-type measurements have depth limitations.  
           Now, the WH311 deep well probe uses a laser static pressure 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; simply fix the level probe 3-5 meters above the deep well pump when the pump is lowered into the well. Suitable for deep well water level measurement and monitoring, solving the problem of deep well water level measurement difficulties, with the following points meeting user needs:

    1

    Component Structure

    Built-in monitoring components: Water level monitoring and water temperature monitoring are completed by one probe.

    2

    Accuracy

    Measurement sensitivity and range: It can accurately measure subtle fluctuations in groundwater level and temperature, and can also monitor a larger range of water level and temperature fluctuations.

    3

    Waterproof Performance

    The WH311 probe adopts a fully welded one-piece structure design, ensuring normal operation underwater at 1000 meters, and each unit will undergo a 20MPa waterproof test (equivalent to 2000 meters underwater waterproof);

    4

    Steel Wire Cable

    Signal transmission uses high-strength polyurethane steel wire cable (during placement, pay attention to protecting the cable) to ensure real-time, high-precision, and stable output of temperature and liquid level measurement signals;

    5

    Protecting the Deep Well Pump

    Real-time display of deep well water level and temperature, with high and low liquid level alarm functions, can be linked with the deep well pump to achieve low-level pump stop function, preventing the deep well pump from burning out.
