Rotamass 3 Remote Rack Converter RCCR31
Brand: Yokogawa Electric CorporationROTAMASS 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
- Field-mount and rack-mount remote converter available
- Refined digital signal processing enables accurate and stable measurement
- A special detector decoupling system makes the device highly independent from external loads or vibrations.
- Simple flow path means self-draining, simple cleaning and suitable for use in hygenic industries.
- High accuracy and high stability over a wide flow range
- Accurate density measurement, up to +/- 0.0005 g/cm³
- Concentration measurement for solutions, suspensions and emulsions (e.g. water cut, net oil computing)
- Volume flow with reference density
- Temperature measurement
- Two analog outputs, two pulse outputs or status-out and one status-in as standard I/O
- Available in explosion proof versions (ATEX, FM, IECEx, EAC, INMETRO, NEPSI, KOSHA)
- European MID approval acc. OIML R-117-1 and American NTEP approval for Custody Transfer Measurement (see GS 01R04B07-00E-E)
