Proven Oil Industry Technology – Reimagined for the Energy Transition.

What was once developed for the fossil fuel industry is now helping shape the future of clean energy. With Hydrox SediSense, Global Hydro brings a field-proven technology from the oil and gas sector into the world of sustainable hydropower. In oil extraction, ultrasonic structure-borne noise analysis has long been used to detect abrasive sand particles in pipelines. We have adapted this robust technology for use in hydropower plants – precisely where it provides maximum benefit.

 

Better than turbidity measurement.

Unlike conventional turbidity measurement, Hydrox SediSense monitors sediment loads precisely where damage actually occurs. Turbidity sensors only indicate how “cloudy” the water is – without providing any reliable assessment of actual damage potential. Additionally, they are often installed kilometers away from the turbine at the intake, are difficult to access, and are susceptible to weather, algae, or air bubbles.

Hydrox SediSense takes a different approach: sensors are mounted directly on the turbine in the powerhouse – outside the water, easy to retrofit, low-maintenance, and highly accurate. This gives operators reliable insights into real sediment risks – enabling targeted action before damage occurs.

 

AI models enable acoustic information to become a reliable basis for decision-making, and digital intelligence to generate a real operational and competitive advantage.

Physics Meets Digital Intelligence

How our Sediment Detection Works.

When sediments are transported through the penstock, they are most damaging where water is redirected, accelerated, or hits solid structures – such as guide vanes, inlet components, or in curved and narrow sections. These sensors detect ultrasonic structure-borne signals generated by the impact of sediment particles. Depending on size, velocity, and hardness, the particles produce a specific acoustic signature. An AI model continuously analyses the turbine’s acoustic signature under optimal operating conditions. Even the slightest deviation – such as altered impact patterns caused by increased sediment load – is detected.

Global Hydro’s machine learning algorithms distinguish between operational noise and harmful sediment impacts, enabling precise identification of risk scenarios. This allows the system to determine the most economical operating mode – including when it’s better to temporarily shut down than risk excessive wear. The AI can also send push notifications to operators and even alert downstream plants in real time.

Turning Data into Insight – and Insight into Strategic foresight

An AI model continuously analyzes the turbine’s acoustic signature under optimal operating conditions. Even the slightest deviation from normal – such as altered impact patterns caused by increased sediment load – is detected. Our data science experts interpret these signals using machine learning and anomaly detection to deliver precise recommendations: when do harmful sediments occur? At what load level does it become more economical to shut down than to continue operation?

This 4-nozzle vertical Pelton turbine turns raw acoustic data into a reliable decision-making tool – and transforms digital intelligence into true operational and strategic value.

Ideal for Alpine Regions with Glacial Catchments.

Hydrox SediSense performs at its best wherever high water pressure meets high sediment content – especially in high-head Francis and Pelton turbines located in alpine or glacial environments. Typical regions include the mountains of Europe and large parts of Asia, such as Nepal, India, or China, where undersized desanding systems are a common problem. In areas affected by seasonal extremes – such as heavy rainfall or sudden snowmelt – Hydrox SediSense ensures reliable, flexible operation. That makes the system a real gamechanger for operators who need maximum performance under demanding conditions.

Easy to Retrofit and Highly Effective.

The sensors are installed outside the water directly on the turbine – without system modification and without the need for external infrastructure at the intake. This makes the solution especially attractive for high-head plants where the intake is often located kilometers away. Thanks to its simple integration into existing systems, Hydrox SediSense is ideal for both new installations and retrofits.

Installation is simple and cost-effective, often requiring only adhesive adapters without drilling or welding. In many cases, the hardware cost is significantly lower than conventional turbidity systems – while offering far superior decision-making data.

Prevention Instead of Reaction.

Global Hydro already offers a wide range of proven and innovative erosion protection solutions – from high-strength materials to intelligent coatings and flow-optimized component design. Hydrox SediSense adds a completely new layer to this portfolio: data-driven prevention.

Instead of reacting to wear after it occurs, operators can take preventive measures – such as targeted shutdowns during high-risk sediment events. This leads to a holistic protection strategy that maximises lifetime and efficiency.

Real-World Results. 

One notable pilot project is the Tumpen-Habichen power plant in Tyrol, operated by TIWAG. Here, Hydrox SediSense provided stable, accurate damage potential measurements in real time via the HydroxConnect portal – outperforming conventional turbidity probes in both reliability and accuracy.
At the Luggauerbach plant in Austria, AI analysis from a 4-nozzle Pelton turbine enabled operators to optimise load distribution between turbines based on sediment tolerance, directly increasing economic efficiency.

Sediments cause wear and rising costs.

Climate change and erosion increase sediment input – threatening efficiency, uptime, and long-term profitability. Conventional detection methods reach their limits.

AI-Based Sediment Detection

Hydrox SediSense identifies sediment loads directly at the turbine using ultrasonic structure-borne sensors and intelligent anomaly detection. Easily retrofittable, highly accurate, and robust against interference.

Longer turbine lifetime, reduced maintenance effort, more efficient operation.

Early detection instead of costly wear: Hydrox SediSense helps you protect your plant, extend its lifetime, and optimize operations. That saves money, secures efficiency – and protects your investment.
