Flow conditioner
If the inlet runs cannot be observed, the use of a flow conditioner is recommended.
The flow conditioner is fitted between two pipe flanges and centered by the mounting
bolts. Generally this reduces the inlet run needed to 10 × DN with full accuracy.

Flow conditioner
The pressure loss for flow conditioners is calculated as follows: ∆ p [mbar] = 0.0085 ⋅ ρ

p = 10 bar abs.
ρ = 965 kg/m

v = 2.5 m/s
v = 40 m/s
∆ p = 0.0085 ⋅ 965 ⋅ 2.5
