The Coriolis flow meter has many features such as direct measurement of mass flow and measurement of fluid density, which other flow meters do not support. Therefore, since being introduced for practical use in the late 1970s, its market has rapidly expanded in many industries such as oil, chemicals, and foods. The YOKOGAWA Group has also been focusing interest on its features and continued R&D in this area. Eventually, following joint R&D with ROTA YOKOGAWA GmbH & Co. KG (Germany), Yokogawa released the ROTAMASS series Coriolis flow meters in 1993 worldwide, mainly for the Europe, North America, and Southeast Asia markets.
Process flow meters must be able to measure flow rates at high speed and accuracy, and must also be robust to withstand stresses and vibrations applied through the process connection with the piping. To achieve these properties, we developed a high speed high accuracy digital signal processing algorithm and a Box-in-Box structure to reduce the impact from external force and vibration. This paper describes the features of the signal processing and structure, and application examples of the ROTAMASS series Coriolis mass flow and density meters.
