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 or 13× DN with full accuracy.
The pressure loss for flow conditioners is calculated as follows: 侏p [mbar] = 0.0085
