* At Qₙₒₘ pressure drop across a parallel tube sensor will be approximately 0.4 bar (6 psi) for H₂0. Sensors can be operated at higher flow rates up to Qₘₐₓ but pressure drop will be higher. Typical Minimum Flow Qₘᵢₙ is the recommended lowest flow rate for an accurate measurement. Sensors will measure flow rates lower than Qₘᵢₙ but uncertainty will increase beyond 1 % of rate.

The flow rate 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.

 

Pressure Drop
*

At Qnom, pressure drop across a parallel tube
sensor will be approximately 1-3 bar (15-44 psi)
for H20.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.
