1 Description RotaMass 3 Series Coriolis Mass Flow Meter; - Integral Transmitter, Model RCCx; - Remote Converter, Model RCCF31; - Remote Converter, Model RCCR31; - Remote Detector Model RCCS3xxxx The Coriolis Mass Flow Meter is used for direct measurement of a gas or liquid mass flow using the Coriolis principle. The integral version combines the detector and the converter in one apparatus; the separate version consists of a converter and a separate detector, connected via a cable. The Detector may be provided with a heat conductor, consisting of heating pipes supplied by a heat conducting medium (e.g. water, oil or gas).
