Rheonik Coriolis Flowmeter RHM 04

GE Measurement & Control RHM 04

RHM 04 Versatile Coriolis Mass Flowmeter with Fast Response Times For Very High Pressure ApplicationsRHM 04

The RHM 04 can maesure flow rates up to 10 kg/min (22 lb/min) with extremely fast response times and excellent repeatability. A very higt pressure version up to 1067 bar is also available, manufactured by GE’s Rheonik mass flowmeter expets.

Advantages

  • Torsion ascillator design assures most stable and basically drift free maeasurement 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

Repeatability

Better ± 0.1% of rate,

Goldline 0.05%

 

Temperature

(*) Nominal flow Qnom refers to roughly 8 – 10 m/s (33 ft/s) velocity in measuring loops for best perfomance.

(**) Selected sensors are only available in combination with temperature option T1, TA, standard material and pressure range

  • Serial/single path versions offer the some accuracy at half the flow (qmax serial version = 5 kg/min)
  • No relevant pressure affect due to tersional ascillation and semi – circle (non-deforming) measurement section
  • Uncertainty of reading (incl. zero drift) indications refer to reference conditions H2O, 18-24C (66 – 76F), 1 – 3 bar (15 – 45 psi) and installation according to field manual.
  • Pressure drop indiactions refer to H2O, with parrallel maesuring loops type P1 and standard manifold block connections
  • For calibration to customer range and / or with improved uncertainty, please consult factory
