The Yokogawa RCCF31 is a Coriolis mass flow converter module from the Yokogawa ROTAMASS 3 series, designed for high-precision measurement of mass flow, density, and temperature in industrial processes.
Unlike standard I/O modules, RCCF31 functions as a field-mounted or remote converter, working together with a Coriolis sensor (such as RCCS series) to provide direct mass flow measurement without relying on volumetric conversion. This makes it highly accurate and stable, even under varying process conditions.
It is widely used in oil & gas, chemical, pharmaceutical, and food industries, especially in applications requiring custody transfer accuracy and real-time process control.
