* At Qnom, the pressure drop across a parallel tube sensor will be approximately 1- 3 bar (15-44psi) for H20. Sensors can be operated at higher flow rates but the 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 the rate.

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