RHM 100

Coriolis Mass Flowmeter for High Flow Applications

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

• 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%.

Uncertainty % DP (bar)

Flow Rate kg/min

• 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.
