Penstock monitoring
Flow measurements on the penstock pipeline of hydropower plants for monitoring of leakages and burst pipes
Hydropower plant penstock pipeline flow monitoring of leaks and bursts
A complex of hydropower plants plays a key role within the municipal utilities of a large German city, offering black start capabilities and energy storage, crucial for balancing fluctuating renewable energy supplies. To safeguard the valley from potential flood risks due to penstock pipeline damage, a modern flow measurement solution was sought. It was important that any operational disruptions were avoided and the pipeline's integrity was assured.

Product Solutions
The FLUXUS SIL F ADM8X27 non-intrusive ultrasonic flow meters are SIL-rated, functional safety approved. As the wetted parts of inline measuring devices are not subject to the Failure Mode Effects and Diagnostics Analysis (FMEDA), they are not included in the scope of certification - presenting a safety risk. The SIL 2 certification of the FLUXUS non-intrusive flow meter includes the entire measuring system -the measuring transmitters and transducers. It also includes the patented WaveInjector mounting fixture for extreme temperatures, allowing the non-intrusive flow measurement at liquid temperatures from as low as -275 °F up to +1100 °F. Flexim also offers special radiation-resistant transducers for use in the nuclear industry.
