  • Dosing
  • Injections
  • Mixing
  • Filling

 

Features

  • Available as very high pressure versions up to 1067 bar
  • Flow uncertainty down to 0.10%
  • Repetability better than 0.05%
  • Unique Torsion Oscillator
  • Typical measuring ranges from 0.5 to 50 kg/min
  • Minimal Flows as low as 0.3 kg/min

  • 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

Better ± 1°C

 

(*) Nominal flow Qnom refers ro roughly 8 – 10 m/s (26 – 33 ft/s) velocity in measuring loops for best perfomance. For PH0 and PHH Construction Type, Qmax and upper calibration limit is 25 kg/min, Qnom is 20 kg/min.

(**) selected sensors are only available in combination with temperature ranges T1, TA, standard material and pressure range.

  • Serial/single path versions offer the same accuracy at half the flow (Qmax serial version = 25 kg/min).
  • No relevant pressure effect due to torsional ascillation and semi-circle (non-deforming) measuring section.
  • Uncertainty of reading (incl. zero drift) indications refer to reference conditions H20, 18-24°C (66-76°F), 1 – 3 bar (15 – 45 psi) and installation according to field manual.
  • Pressure drop indications refer to H20, with parallel measuring loops type P0 and standard manifold block connections.
  • For calibration to customer range and/ or with improved uncertainty, please consult factory.
