* At Qnom, pressure drop across a parallel tube sensor will be approximately 1- 3 bar (15-44psi) forH20. Sensors can be operated at higher flow rates but pressure drop will be higher.Qmin is the recommended lowest flow rate. Sensors will measure flow rates lower than Qmin, but uncertainty will increase beyond 0.5% of rate.

The flow specifications above relate to standard pressure, parallel tube, manifold sensor versions. Models with higher pressure ratings have increased wall thickness and will have higher pressure drops
