GE RHM 15 User manual

RHM 15
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, ...)
Medium Sized Coriolis
Mass Flowmeter
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

Pressure Rating RHM 15
The maximum pressure (pmax) of a sensor is determined by its weakest part. The weakest part can be the measuring
loops (pmax indicated below) or the construction type (pmax indicated in the Basic Order Code section, last page) or the
selected anges / ttings (for pmax please see respective standard).
