- Mechanical installation

 2.3.2 I

Installation in nozzle

Installing the 

PTU50-51-56 

sensor in a nozzle (see fig.10), make sure the sensor 

bottom protrudes at least 10 mm from the bottom nozzle

PTU50-51-56 

can be installed in an extension 

pipe (see Figure 11) to turn away the sensor 

from the maximum level point. The extension 

pipe  must  be  flat  and  without  joints  (welds, 

etc..), also, the pipe terminal part must be cut 

at 45° and with the borders without burr.

 

2.3.1 

Blind distance

During installation is important to remember that in the 

sensor vicinity there is a blind zone (or 

BLIND DISTANCE

of 

0.05m

 (for 1.5m max 

PTU50 

range), 

0.3m

 (for 6m max 

PTU51 

range) or 

0.5m

 (for 12m max 

PTU56 

range) where 

the sensor can not measure.

2.3 Mounting precautions

  2.3.1 

Mounting position (Fig.8)

 - With cambered roof, Do not install the  

   sensor in the tank center (b).   

 

   Leave a 300mm minimum distance    
   between the sensor and the tank  

 

   smooth wall (d). 
 - Use a protective cover to protect the  
   sensor from weather and direct sunlight (c).

 - Do not install the sensor near the load zone (a).

 - Make sure that in the sensor emission  
   beam (lobe “ ”) there are no obstacles  

   (f,s) that can be intercepted as level.

 - Make sure that there is not foam   

 

   presence on the product surface to be  
   measured
