Mounting sensor to a bracket 

Mounting the sensor to the 45° angled bracket is done via an adapter and M20 nut, as 
shown in Fig.3:   

 

 

 

 

 

 

 
 
 
 
 
 
 
 
 
 
For correct installation, we recommend that the adapter is threaded on the cable, and 
carefully screwed onto the 

MicroFlow-i

 before fitting to the bracket.  This will reduce 

the risk of any ’twisting’ in the cable.  
Ensure that the sensor is tightened and the dot is in the correct position. 

 

 
 
 

 
 
 
 
 
 

Important Information 

When fixing the sensor to the adapter, ensure that care is taken when 
pulling the sensor cable through.  And once attached to the adapter, and 
the M20 nut is tightened, the green dot should be central to the 
movement of flow as shown in Fig.4.
