(**) 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 = 750 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 field
manual.
• Pressure drop indications refer to H
2
O, with parallel
measuring loops type P1.
• For calibration to customer range and / or with
improved uncertainty, please consult your local
agent.

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