The water level is measured as it flows through the structure. Discharge rates are determined by using a site-unique rating curve and the water level. A float and pulley system, strain gage pressure transducer, or ultrasonic sensor may be used in stilling wells to measure water level fluctuations, then calculate flow. German spot power prices are currently firm traders said with wind and more lignite availability to ease some of the bullishness caused by low water levels. On Friday EnBW also announced a planned outage for MW RDK 8 hard coal plant in Karlsruhe from October 27 to November 1, with its MW Heilbronn coal plant out from November 3 for a. The CRSV consists of a submersible water-level and water-temperature sensor with its own time clock and memory to store the collected data—in a compact stainless-steel case.
