Electrical & mechanical installation manual                730962.31.00                                   page 43 of 52 

 

5.2.3 

Pressure testing of a gas pipeline with liquid (water) 

 

 

For example when a pipeline in which the OPTISONIC 7060 is installed will be pressure tested with 
a liquid (water) the following precautions must be taken to prevent the transducers from getting wet: 

•

 

The transducers must be removed.  

•

 

Blindstops must be fitted in the tranducer positions. A set of blindstops can be ordered at 
KROHNE. 

For the detailed procedure to remove and refit the transducers, consult the service manual.
