GE RHM 03 User manual

RHM 03
g
The RHM 03 can measure ow rates up to 5 kg/min
with temperatures up to 350°C and pressures up
to 1067 bar with the unique Omega shape sensor
technology. A most exible model, manufactured by
GE’s Rheonik mass owmeter experts.
Applications
• General control • Dosing • Mixing
• Batching • Injections • Filling
Features
• Available as very high pressure version up to
1067 bar
• Flow uncertainty down to 0.10%
• Repeatability better than 0.05%
• Unique torsion oscillator
• Typical measuring ranges from 0.05 kg/min to 5
kg/min
• Minimal ows as low as 38 g/min
Versatile Coriolis Mass
Flowmeter for Low Flow
and Very High Pressure
Applications
• Customization possible
• Extra compact design with minimal space
requirement
• 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

Pressure Rating RHM 03
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).
