COMPRESSED AIR AT ITS BEST

 

3:  

Installation position horizontal, flow horizontal to the rear, 

 

  

sensing element to the left (heated sensing element upwards)

 

4:  

Installation position vertical, flow direction horizontal to the right,   

  

sensing element upwards

 

5:  

Installation position horizontal, flow direction vertical upwards, 

 

  

sensing element to the rear

 

6:   

Installation position horizontal, flow horizontal to the rear, sensing  

  

element to the right (heated sensing element downwards, problems  

  

may occur with low flow rates)

5.4  

Required measuring distance

Notes

Please observe the 

required inlet and outlet distance

 to reach the 

specified measuring accuracy. The inlet distance is the piping line 
length 

upstream

 of the measuringSYSTEM, the outlet distance the 

piping line length 

downstream

 of the measuringSYSTEM with the 

flow direction of the fluid.

 

Total measuring distance = inlet di outlet distance

 

Outlet distance = 5 x D

 

Inlet distance = 15 x D + B

 

D = pipe diameter [mm]

 

B = Additional flow calming section

5  Montage

Befolgen Sie die Vorschriften und Bestimmungen für Errichtung und Betrieb 

von Druckluftanlagen�

5.1  Montageort

• 

Hinter dem Kältetrockner / in der Nähe des Verbrauchers�

• 

Wird Druckluft über parallele Leitungen in die Hauptleitung eingespeist, sollte 

das Gerät in der Hauptleitung montiert werden�

• 

Möglich ist auch Einbau nach der Wartungseinheit (verwenden Sie für die 

Verbraucher Öl, muss das Gerät vor dem Öler eingebaut werden)�

5.2  Einbaubedingungen

Um die spezifizierte Messgenauigkeit zu erreichen, müssen folgende Einbau-

bedingungen eingehalten werden: Definierte Ein- / Auslaufstrecken, definierte 

Strömungs-Querschnittsfläche, feste Eintauchtiefe und lagerichtige Positionierung 

der Messelemente�
Das Gerät ist auf einer Messstrecke montiert, die diese Bedingungen erfüllt�
Bei Störungen an der Einlaufseite werden zusätzliche Beruhigungsstrecken (B) 

empfohlen:

Änderungen des  

Rohrdurchmessers

B = 5 x Rohrdurchmesser

90°-Krümmer

B = 5 x Rohrdurchmesser

zwei 90°-Krümmer, eine Ebene

B = 10 x Rohrdurchmesser
