FIP FLS F6.61 Manual page 7

Set the sensor to work
The assembly and set to work of the instrument are carried out by two simple
steps that allow a quick and precise installation:
1. INSTALLATION OF THE SENSOR ON THE WET-TAP CLAMP SADDLE
2. VERTICAL POSITIONING OF THE SENSOR INTO THE PIPE
Warning: the F6.61 allows installation into pressurised pipes without system
shutdown; we recommend to pay maximum attention when screwing the
clamping bolts of the measuring rod. The rod is pushed upwards by the
internal pressure, for this reason not work up the rob.
Note: lubricate the steel rod to reduce frictions with the O-rings. This will help
the installation, measurement and positioning operations.
1. INSTALLATION OF THE SENSOR ON THE WET-TAP CLAMP SADDLE
Warning: these installations steps can be applied to every wet-tap clamp
saddle with the following properties:
-Branch minimum diameter : 33 mm
-Branch thread : 1 1/4" GAS (cylindrical)
• Assemble the saddle or weld-on the adapter in the desired position to install
the sensor.
Drill the pipe. Use a 35 mm ( in.) milling cutter.
Remove the drilling machine. Be careful to block the fluid using the proper
intercepting plate or ball valve (see Fig. 1).
• Wrap several turns of Teflon tape around the steel joint threads to prevent
leaks. Screw the Stainless Steel joint, together with the measuring rod and the
sensor, in the saddle branch.
• Be careful to fix the sensor body in the upper position (see Fig.2).
• Tight the safety chain and fix it.
• Remove the intercepting plate or open the ball valve to the full open position
(perpendicular to pipe).
