SGM-101F - 

transducers positioning

6.5.2 V and W type positioning

For a correct transducers positioning, proceed as follows:

1) Identify point “A”, which will be the mounting position of the 

fi

 rst transducer.

A

2) From point “A” draw a straight line “S” parallel to the pipe axis, and equal to the value, showed in M25,

previously calculated to identify point “E”.
