Application

A large power plant needed a redundant overfill protection system for four of its boilers. Planning and implementation of the project were carried out by the engineering firm Wolter & Dros B.V. The heat exchangers, which were already equipped with mechanical float switches, have an output of 6000 kW each. The biggest danger in this application is the occurrence of hydraulic shock. A good overfill protection system must be able to survive such abrupt pressure surges unscathed. To provide twofold safety, the sensor should be based on a completely different measuring principle. By using two different measuring principles, systemic flaws can be eliminated.
