RHM 30
Medium Sized Coriolis
Mass Flowmeter
The RHM 30 can measure flow rates up to 750 kg/min
(1653 lb/min) with temperatures in excess of 350°C
and pressures up to 490 bar. This model is medium
sized with true reliability for a versatile solution,
manufactured by GE's Rheonik mass flowmeter
experts.
Applications
• General control • Dosing • Mixing
• Batching • Injections • Filling
Features
• Suitable for pressure up to 490 bar
• Flow uncertainty down to 0.15%
• Density uncertainty down to 0.5%
• Repeatability better than 0.05%
• Unique torsion oscillator
• Typical measuring ranges from 7.5 to 750 kg/min
• Minimal flows as low as 5 kg/min
• Optimized solutions for batching operation
g
• Customization possible
• Hazardous Area Approvals (ATEX, CSA, ...)
Advantages
• Torsion oscillator design assures most stable and
basically drift free measurement and increased
signal to noise ratio
• Not sensitive to changes in pressure
• Longest life time and increased safety (low stress
in welds and increased wall thickness against
abrasion)
• No moving parts, practically no maintenance
• Removable connection manifold available
