B-2 Calculating P and L Dimensions
To determine P, you need the following:
the pipe inside diameter (ID)
the wall thickness (WT)
the installed pipe coupling length (CL)
the transducer face depth (FD)
the mounting angle (MA)
Use Figure B-2 to properly measure the coupling length.
Typically, the transducer face is positioned just outside the inside
diameter (ID) of the pipe, or slightly retracted inside the coupling.
