RHM 15
Medium Sized Coriolis
Mass Flowmeter
The RHM 15 can measure ow rates up to 200 kg/
min (440 lb/min) with temperatures in excess of
350°C and pressures up to 540 bar. This model
is truly a reliable solution, manufactured by GE’s
Rheonik mass owmeter experts.
Applications
Used in industry for ow measurement applications
requiring high mass ow accuracy.
• General control • Dosing • Mixing
• Batching • Injections • Filling
Features
• Suitable for pressure up to 540 bar
• Flow uncertainty down to 0.12%
• Density uncertainty down to 0.5%
• Repeatability better than 0.05%
• Unique torsion oscillator
• Typical measuring ranges from 2 to 200 kg/min
• Minimal ows as low as 1 kg/min
• Optimized solutions for batching operation
• 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
