(*) 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.
