(*) Nominal flow Qnom refers to roughly 8 - 10
m/s (33 ft/s) velocity in measuring loops for best
performance.
(**) 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 = 5 kg/min).
• No relevant pressure effect due to torsional oscillation
and semi-circle (non-deforming) measurement
section.

• Uncertainty of reading (incl. zero drift) indications refer
to reference conditions H
bar (15 – 45 psi) and installation according to field
manual.
• Pressure drop indications refer to H
measuring loops type P1 and standard manifold block
connections.
• For calibration to customer range and / or with
improved uncertainty, please consult factory.
