6. Standard Sensor Removal

To remove the sensor from a depressurized empty pipe, simply remove the cap nuts and upper hex nuts located above the sensor
fl ange. Pull up on sensor fl ange with twisting motion.

G. Position the installation tool bearing plate by rotating it so that it is approximately 40 mm (1.6 in.) from the swivel mount. Mount

the installation tool by placing the threaded rods through the holes in the tool's bearing plate, resting the bearing plate on top of
the protector plate hex nuts. Make sure the swivel mount's ears are mounted between the threaded rods (not over the rods).
Install the bearing plate cap nuts. Tighten the bearing plate cap nuts to secure the installation tool in place. (Fig. 13)

H. Align the sensor cable with the swivel mount cable port to prevent cable pinching. Use a 3/8 inch wrench or socket to turn the

installation tool shaft clockwise until it is seated in the hole at the top of the sensor fl ange.

I. Wearing safety face protection, slowly open the isolation valve to the full open position. Loosen the lower hex and

jam nuts and move them to the proper "H" dimension. Turn the installation tool shaft clockwise until the sensor fl ange
contacts the lower hex and jam nuts. Thread the upper hex nuts down until they contact the sensor fl ange. Tighten the
upper hex nuts to secure the sensor. (Fig. 14)

J. Remove cap nuts and withdraw the installation tool. Be careful to not damage cable. Replace protector plate and cap nuts.
