Rotamass 3 RCCT3 Integral Converter
Brand: Yokogawa Electric Corporation
ROTAMASS is a Coriolis mass flowmeter with highly refined digital signal processing electronics, so that accurate and stable mass flow measurement is achieved.
ROTAMASS employs a flame-proof type converter case suitable for use in the hazardous area together with it’s intrinsically safety type detector.
ROTAMASS's signal processing, housing protection and its detector's special decoupling system against external loads and vibrations, realize high performance in real applications.
Features- ROTAMASS is a flowmeter for nearly all fluids, including high viscosity liquids, slurries and multi-phase media with a certain gas content
