PENSTOCK LEAK DETECTION SYSTEM (PLDS) Highly accurate monitoring for public and environmental safety

Safety for people and the environment Unique concept for safe and early detection of damages Leaks in pressure pipelines can cause large-scale environmental damage and even fatalities leading to substantial losses and reduced public confidence in hydropower plants. Penstocks may constitute a significant potential risk; not only due to stresses from the high internal pressure, but also from external factors such as extreme weather, earthquakes, climate change, material fatigue, and increasing population densities in the vicinity. In several well-documented cases, undetected leaks have led to flooding...

Comprehensive protection Precise monitoring with convenient control A standard Rittmeyer PLDS provides three levels of continuous monitoring: rupture, leak and fine leak detection. Thresholds, time delays and corresponding actions are easily configured to match the specific requirements on site. With the integration of additional sensors (level sensors, pressure switches, etc.), even more precise monitoring of critical locations is possible. All components can be controlled locally or remotely at any time via the web interface of the Instrumentation Controller to optimize the system performance....

Custom solutions Flexible measurement setups for tailor-made protection Rittmeyer offers several PLDS setups to fit your application and budget: Standard setup: Highest precision possible with two Rittmeyer flow meter systems (up- and downstream position). Combined setup: Economic combination of one Rittmeyer flow meter system and a Rittmeyer pressure system or a different flow meter. Simple setup: One single Rittmeyer flow meter system at only the upstream position. All setups are also available with clamp-on sensors, e. g. if drilling is not possible.
