Groundwater level and temperature monitoring solution for the mining industry

I. 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 reserves, 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. It is suitable for monitoring sites with harsh environments and can realize data acquisition, storage, alarm, and transmission of underground wells, fire safety, dam health, water supply and drainage networks, etc., especially suitable for underground applications.

II. System Overview 
        The WH311 groundwater level measuring instrument 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. It can monitor the water level and temperature of groundwater. The matching display recorder can record data in real time, generate various reports and curves, and provide data analysis and decision-making basis for customers. This system is an important means of grasping the changing laws of groundwater, understanding the groundwater exploitation status, and guiding groundwater resource protection.

III. Application Challenges: 
        1. Complex environmental conditions: Equipment often faces complex environments such as high temperature and high pressure, requiring instruments to have excellent anti-interference ability and durability. 
        2. Continuous operation: The system needs to operate continuously, so the monitoring system must have high reliability and stability to ensure long-term continuous monitoring. 
        3. Data integration and real-time performance: It is necessary to integrate and analyze various monitoring data in real time to enable rapid response and adjustment, ensuring the safe and efficient operation of the system. 
        4. High-precision, high-security, and high-stability products are required. 
        5. Maintenance difficulty: The equipment is difficult to maintain, and the monitoring instruments need to be easy to maintain and repair to reduce downtime.

IV. Solution Advantages: 
        1. High anti-interference ability: Our instrument design has strong anti-electromagnetic interference ability, enabling stable operation around the equipment and ensuring the accuracy and reliability of the data. 
        2. Durability and stability: Using high-quality materials and advanced manufacturing processes, the instrument can operate stably for a long time in high-temperature and high-pressure environments, reducing failure rates and maintenance costs. 
        3. Real-time data processing: Equipped with a high-performance data processing unit, it can collect, process, and display monitoring data in real time, supporting quick decision-making and response. 
        4. Supports intelligent system integration: Our solution integrates advanced sensors and intelligent control systems to achieve comprehensive monitoring and control of multiple parameters, optimizing the production and transmission process. 
        5. IP68 protection level, polyurethane steel wire cable tensile force to cope with deep-water pressure environment. 
        6. Convenient maintenance design: The instrument is designed for easy installation and maintenance, reducing maintenance time and costs, and improving the overall operating efficiency of the system.

       7. Products support third-party metrological identification with an error of less than 1 centimeter. 
        8. Provides an intelligent solution for recording liquid level signals. 
 

V. 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 and 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 the 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.

       The following points meet user needs: 
       Requirements for pumping test monitoring equipment and transmission systems. 
       Install one set of automatic groundwater monitoring equipment, which can measure and record water level, water temperature, and other elements, and can automatically record data; the automatic recorder housing is made of stainless steel, with a simple structure and small size; the monitoring frequency is optional (1S-4 minutes), and the data storage capacity is not less than 200,000 entries; data can be exported directly in tabular format.
