Coriolis mass flow meter


Development at the highest level

“High end” simulation technology enables the analysis and coupling of different models such as CSD (FEM), CFD, CEM, FSI, TFSI, saving much of the time that would have had to be invested in finding solutions in the past. This is our way in the future to solve highly complex measurement tasks for our customers.

By using the latest technologies, we are able to quickly identify and overcome application obstacles and provide optimal solutions for our customers.
