RHM 15

The RHM 15 can measure flow 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 flowmeter experts.

Applications

Used in industry for flow measurement applications 
requiring high mass flow 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 flows 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
