RHM 160

Coriolis Mass Flowmeter for Very High Flow Applications

The RHM 160 can measure ow rates up to 1800 t/h (66,140 lb/min) with pressures up to 50 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

• Oil exploration

• Highly viscous media (low pressure drop and excellent performance at low ow conditions)

Features

• Suitable for pressure up to 50 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 750 to 30000 kg/min

• Minimal ows as low as 600 kg/min

Advantages

• High ow rates for fast lling

• 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

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.

(*) 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.

• Calibration at factory only up to 11,000 kg/min.

• Pressure drop indications refer to H2O, with measuring loops type P1.

• For calibration to customer range and / or with improved uncertainty, please consult your local agent.
