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.

Metering of liquids and gases, viscous and corrosive media. Fields of application: Chemical, petrochemical, oil and gas, food, pharmaceutical. The TMU Series can also be used for precise dosing, loading and unloading systems as well as for custody transfer applications.


Particularly robust sensor housing made of cast iron, insensitive to external vibrations and pipeline forces

Special features

Simultaneous measurement of mass flow, density, temperature and volumetric flow.
Extremely cost-effective heating by means of steam or liquid
