Proline Prowirl R 200 HART Installation
Endress+Hauser 25
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.

1 Flow conditioner
The pressure loss for flow conditioners is calculated as follows: ∆ p [mbar] = 0.0085 ⋅ ρ
[kg/m
3
] ⋅ v

[m/s]
Example for steam Example for H
2
O condensate (80 °C)
p = 10 bar abs. ρ = 965 kg/m
3
t = 240 °C → ρ = 4.39 kg/m

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

= 51.3 mbar
∆ p = 0.0085 ⋅ 4.394.39 ⋅ 40

= 59.7 mbar
ρ : density of the process medium
v: average flow velocity
abs. = absolute
