RHM 80
g
Applications
•Loading of boats, vessels, rail tank wagons
•High temperatures and other challenging
applications
•Highly viscous media (low pressure drop and
excellentperformanceatlowowconditions)
Features
•Suitable for pressure up to 198 bar
•Flow uncertainty down to 0.15%
•Density uncertainty down to 0.5%
•Repeatability better than 0.05%
•Unique torsion oscillator
•Typical measuring ranges from 200 to 8000 kg/
min
Large Coriolis Mass
Flowmeter
TheRHM80canmeasureowratesupto480t/h
(17,637lb/min)withtemperaturesinexcessof280°C
and pressures up to 198 bar. This large sized model
is also appropriate for tough application conditions,
manufacturedbyGE’sRheonikmassowmeter
experts.
•Minimalowsaslowas130kg/min
•Customization possible
•HazardousAreaApprovals(ATEX,CSA,...)
Advantages
•Highowratesforfastlling,incombinationwith
high operating pressure
•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

Measurement & Control

Pressure Rating RHM 80
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selectedanges/ttings(forpmaxpleaseseerespectivestandard).Foroptional
materials like Alloy C22, wall thickness of measuring loops may change by +/- 10%.
