  • No moving parts, practically no maintenance
  • Removable connection manifold available

Repeatability

Better ± 0.1% of rate,

Goldline 0.05%

 

Density

Down to 0.5% uncertainty

 

Temperature

Better ± 1°C

 

(*) Nominal flow Qnom refers to roughly 8 – 10 m/s (26 – 33 ft/s) velocity in measuring loops for best perfomance.

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

 

Serial/single path versions offer the same accuracy at half the flow (Qmax serial version = 50 kg/min).

No relevent pressure effect due to torsional ascillation and semi-circle (non-deforming) measurement section.

Uncertainty of reading (inch. zero drift) indications refer to reference conditions H2O, 18-24°C (66-76°F), 1 – 3 bar (15 – 45 psi) and installation according to field manual.

Pressure drop indications refer to H2O, with parallel measuring loops type P1 and standard manifold block connections.

For calibration to customer range and/ or with improved uncertainty, please consult factory.
