ROTAMASS Total Insight

In the last decade, the use of Coriolis flowmeters has been changing from general purpose to supporting your needs in specific applications.
While the technological complexity increased, the demand for simple operation and handling is also a rising requirement.
Yokogawa answers these needs by offering six dedicated product lines with two specialized transmitters allowing the highest flexibility - the ROTAMASS Total Insight.

Total Insight
The ROTAMASS philosophy gives Total Insight throughout the whole lifecycle.
To facilitate optimal processes and increase the efficiency of personnel, Yokogawa has placed a strong focus on simplifying fundamental operating concepts with Total Insight. The Total Insight concept is built in to the latest generation of Rotamass transmitters and provide enhanced settings for customized setups, pre-defined trend views, or multiple configuration sets for fast changeover in batch production are supported.
