Installation of GF Signet 2540 and 2517 wet-tap flow sensors requires a wet-tap drilling machine,
a ball or gate valve, a pipe nipple with 1.25″ threads and a GF Signet wet-tap installation tool. The
valve and pipe nipples can be purchased at a local hardware store.
The GF Signet wet-tap installation tool serves to hold the sensor against the line pressure as it is
retracted or inserted into the pipe.
