Proven solution for aggressive media and demanding industrial applications
The TMU-T Coriolis mass flow meter from Heinrichs Messtechnik GmbH has been specifically developed for processes involving highly aggressive media and demanding operating conditions. Featuring wetted parts made of high-purity tantalum, the instrument offers maximum corrosion resistance and enables safe and precise measurement even with highly corrosive liquids and gases.
Especially in applications involving highly concentrated acids or chemically demanding process media, the TMU-T sets new standards in material resistance and process reliability. The specially engineered sensor design provides excellent corrosion protection while ensuring stable and accurate measurement under extreme chemical and thermal conditions.
Thanks to its compact fully welded design, high temperature stability, and excellent vibration resistance, the TMU-T is ideally suited for critical applications in the chemical, petrochemical, semiconductor, and pharmaceutical industries. Whenever standard materials are no longer sufficient, tantalum provides a reliable and durable solution.
In addition to direct mass flow measurement, the TMU-T also measures density and temperature, providing valuable process data for accurate monitoring and process optimization.
The TMU-T Coriolis mass flow meter with tantalum combines maximum corrosion resistance with high measurement accuracy and robust sensor technology. For applications involving aggressive media where standard materials reach their limits, the TMU-T provides a reliable and durable solution for safe process monitoring and maximum plant availability
