Rough and fine sediment in the water catchment
In the alpine countries, water makes a very large contribution to energy production. The hydroelectric power stations are supplied from the surrounding mountains partly via kilometre-long feed tunnels. To extend the service life as long as possible, sediment and debris carried by the water must not be allowed to reach the turbine chamber. For that reason, special rakes are used in the settling pond to remove sediments. If the sediments reach a maximum level in the settling pond, an automatic flushing procedure is usually started.
VEGAVIB 62 for detection of sediment in the water catchment
The VEGAVIB 62 sensor is ideal for underwater detection of solid materials and therefore a viable alternative to radiometric level measurement. When the vibrating rod is covered with sediment, a switching command is outputted. This triggers an automatic flushing process. Cyclical flushing is thus eliminated, which results in optimal utilisation of the turbine. The vibrating rod is outfitted with a cover for protection against rockfall.
Level measurement in the inlet with VEGASON 62
VEGASON 62 measures how much water, if any, is in the catchment. Mounted on a frame over the catchment inlet, it measures the current filling level with high precision. Due to the contactless measuring technique, an absolutely wear-free and thus maintenance-free operation is ensured. To set up the instrument, it suffices to enter the start (0%) and the end value (100%) in meters. These features, combined with its economical price, make it an unbeatable level gauge for the water catchment.
