2.11 Sealing  

Sealing of the DUT-E is carried out by means of cord and disposable plastic seal (included in 
delivery set). 
 
In  order  to  seal  the  sensor  you  need  to  put  the  cord  through  the  sealing  holes  of  the 
mounting plate and DUT-E housing, after that put the free cord ends through two openings 
in the center of the seal. The cord will be fixed after the seal has been locked. 
 
Separation of the seal without its breaking is not possible! 
 
If necessary, you can use seals of other models and manufacturers. 
 

ATTENTION! 

The cord of the seal shouldn’t touch the tank!
