GE RHM 100 User manual

RHM 100
g
The RHM 100 can measure ow rates up to 720
t/h (26,455 lb/min) with pressures up to 189 bar.
This large sized model is optimal for loading and
unloading applications - manufactured by GE’s
Rheonik mass owmeter experts.
Applications
• Loading of boats, vessels, rail tank wagons
• Highly viscous media (low pressure drop and
excellent performance at low ow conditions)
Features
• Suitable for pressure up to 189 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 300 to 12000 kg/
min
• Minimal ows as low as 200 kg/min
• Heavy duty version available (increased wall
thickness of measuring loops for additional safety)
• Customization possible
Coriolis Mass Flowmeter
for High Flow Applications
• 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

Pressure Rating RHM 100
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%.

(*) Nominal ow Qnom refers to roughly 8 - 10 m/s
(26 - 33 ft/s) velocity in measuring loops for best
performance.
(**) Selected sensors are only available in combination
with temperature options T1, TA, standard material and
pressure range.
• Uncertainty of reading (incl. zero drift) indications refer
to reference conditions H2O, 18-24°C (66 - 76°F), 1 - 3
bar (15 – 45 psi) and installation according to eld
manual.
• Calibration at factory only up to 11,000 kg/min.
• Pressure drop indications refer to H2O, with measuring
loops type P0.
• For calibration to customer range and / or with
improved uncertainty, please consult your local
agent.
