On July 19, 2025, China YaJiang Group—a newly formed, centrally owned “national team” enterprise—officially kicked off the Yarlung Tsangpo River Lower Reaches Hydropower Project. With a planned investment of about ¥1.2 trillion (around $165 billion), it’s set to become the largest and most technically challenging hydropower complex ever built.

As construction begins, it will need a wide range of advanced industrial sensors and monitoring tools to keep operations safe, efficient, and environmentally friendly. So, what exactly will be used? Here are eight types of essential equipment that will be at the heart of construction, monitoring, and automation.

1. Level Sensors for Reservoir and Sluice Control

Accurate liquid level monitoring is crucial for managing water intake, regulating flow through tunnels and dams, and maintaining the balance between power generation and flood control. Our submersible level transmitters and non-contact radar level meters are ideal for these scenarios, offering long-term stability even in harsh river conditions.

2. Pressure Sensors for Pipeline and Turbine Monitoring

Monitoring pipeline and turbine inlet pressure helps prevent system overloads and detects potential blockages. Our industrial-grade pressure transmitters can operate under high-pressure and high-vibration environments typical of hydropower plants.

3. Flow Meters for Intake and Outlet Measurement

Precise flow measurement is vital for optimizing energy output and tracking real-time water usage. We offer a full range of electromagnetic flow meters and turbine flow sensors to match varying pipe diameters and installation needs.

4. Flow Velocity Instruments for Hydrology and Safety

Real-time flow velocity monitoring supports flood forecasting, and early warning systems. Our non-contact radar velocity meters are particularly suited for wide, and fast-moving channels.

5. Rain Gauges for Catchment Area Monitoring

In mountainous regions with fluctuating rainfall, rain sensors help predict water inflow and manage dam discharge. Our tipping bucket rain gauges are widely used in hydrological stations.

6. Wind Speed and Direction Sensors for Site Safety

High-altitude construction requires constant wind monitoring to protect cranes, workers, and temporary structures. We provide anemometers and wind vanes with robust designs that resist corrosion and deliver accurate data in real time.

7. Digital Display Instruments for Local Readouts

Our multifunction digital displays can integrate with flow, level, or pressure sensors, offering a user-friendly interface for on-site engineers to track sensor data and alarm conditions.

8. Cloud Platforms for Remote Monitoring

We also offer cloud platforms, allowing remote and real-time monitoring via PC or APP. And it supports integration with existing systems or devices.

As a trusted manufacturer of smart instrumentation for over 20 years and one of the measuring instrument suppliers of Three Gorges Dam, we are proud to contribute reliable sensing solutions.
