Mine Pressure and Flow Monitoring

　　The system comprises an explosion-proof sensor, an underground data acquisition terminal, and a cloud-based management platform, with external power supply. The complete solution is certified for coal‑mine safety and is compatible with intrinsically safe, explosion‑proof applications in underground gas‑controlled environments.

　　The integrated sensor provides simultaneous monitoring of both pressure and flow, featuring a built-in high-precision chip. The MHI interface displays real-time readings, while local data storage retains records for over one month. Historical trend curves can be accessed directly from the terminal without opening the device, eliminating potential safety risks associated with opening the enclosure. It supports parallel connection of multiple measurement points and Wi‑Fi wireless transmission.

　 　Core application scenarios:

　　1. Real-time online monitoring of underground gas drainage pipeline pressure and extraction flow rate;

　　2. Monitoring of flow rate and pressure in underground dust-control static-pressure water supply and high-pressure grouting pipelines;

　　3. Monitoring of operating conditions for coal seam water injection and hydraulic fracturing high-pressure pipelines, compatible with 60 MPa high-pressure service.

　　4. Long-term monitoring of flow and pressure in underground fire-fighting and drainage system pipelines.

　　 Core Competency Expansion:

　　Explosion-proof and traceable: Full‑chain explosion protection, suitable for high‑gas and coal‑dust hazardous working environments; data is stored with time‑stamped encryption and is tamper‑proof, meeting safety supervision and traceability standards to mitigate the risk of penalties.

　　Wide measurement range and stable operation: withstands pressures up to 60 MPa and delivers flow rates of up to 45 m³/h, making it suitable for gas drainage and high-pressure water injection applications; features multi-stage lightning protection and strong anti-interference capabilities, ensuring drift-free downhole measurements and long-term reliable accuracy.

　　Low operational costs: The sensors have long calibration intervals, and they are paired with standard explosion-proof mining cables, reducing labor‑intensive maintenance efforts.

　 　Supporting extended features:

　　Data Statistics: Automatically generates daily, weekly, and monthly reports on total gas drainage volume and water consumption, with one-click export support.

　　Power Supply Compatibility: Two optional power supply options are available—standard 127V AC for underground use and solar‑powered lithium‑ion batteries.
