RHM 04
Versatile Coriolis Mass
Flowmeter with Fast
Response Times for Very
High Pressure Applications
The RHM 04 can measure flow rates up to 10 kg/min
(22 lb/min) with extremely fast response times and
excellent repeatability. A very high pressure version
up to 1067 bar is also available, manufactured by
GE's Rheonik mass flowmeter experts.
Applications
• General control • Dosing
• Batching
• Injections
Features
• Available as very high pressure version up to 1067
bar
• Response times of 30 ms and better
• Flow uncertainty down to 0.10%
• Repeatability better than 0.05%
• Unique torsion oscillator
• Typical measuring ranges from 0.1 to 10 kg/min

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

- Page 5 Pressure Rating RHM 04 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 flanges / fittings (for pmax please see respective standard).
