Sensor Tube Orientation 

 
PCME supply instruments with 2 options of probe tube orientation. This is to satisfy the following 
installation requirement: 
 

•

 

the Inner Tube must not obstruct the direction of flow 

 

•

 

the enclosure must be installed with the cable glands and air purge entry pointing 
downwards. 

 
 
On the site survey form specify one of the following options: 
 

 
VERTICAL 
 

 
Flow direction from down to up 
Flow direction from up to down 
 

 
HORIZONTAL 
 

 
Flow direction from right to left
