Case Histories

deltawave - Accurate in big pipes

Outtake of cooling water? Turbine and pump control? Monitoring of the outflow?
deltawave is meant for partially filled and filled pipes. Different types of transducers ensures an accurate and reliable measurement even in case of rough conditions. It is possible to mount the transducers inside the pipe. Using the systec quick-lock system (ball valve) it is even possible to install the transducers uninterruptible from the outside. Expensive downtimes are avoided from the beginning.

Optimierte Montagelösungen

The mounting of the transducers is optimized for your individual application. It’s no odds if you have a filled or partially filled pipe. Beside the internal mounting we develope mounting solutions for the most of all applications. So it is possible to offer uninterruptible mounting and service operations using the quick-lock-system. You give us a drawing or a sketch from the measurement site and we recommend the individual mounting solution. The gallery below shows some installation examples.
