• If there are several flow disturbances present, the longest specified inlet run must
be maintained.
• If the required inlet runs cannot be observed, it is possible to install a specially
designed flow conditioner → 24.
The inlet run correction function:
• Makes it possible to shorten the inlet run to a minimum length of 10 × DN in the
event of flow obstructions 1 to 4. An additional measuring uncertainty of ±0.5% o.r.
occurs here.
• Cannot be combined with the wet steam detection/measurement application
package. If wet steam detection/measurement is used, the corresponding inlet runs
must be taken into consideration. It is not possible to use a flow conditioner for wet
steam.
Flow conditioner
If the required inlet runs cannot be observed, it is possible to install a specially designed
flow conditioner which can be ordered from Endress+Hauser. The flow conditioner is fitted
