6.4.3 Installing a New Transducer in a Pressurized Pipe (cont.)
7. While standing clear of the transducer, open the ball valve on the meter body holder.
8. Close the hydraulic pump valve. Pump the hydraulic ram up to 1500 psi to push the transducer into the meter
body and hold it in place.
9. Align the flange holes of sensor flange with the tapped holes in the holder. Apply anti-seize lubricant to the flange
bolts, install 3/8" lock washers and loosely bolt the flange to the holder. Using a torque wrench, tighten the four
bolts to 15 ft-lb in the order shown in Figure 77 on page cv. Then, tighten the four bolts to 30 ft-lb in the same
order shown in Figure 77 on page cv.
10. Release pressure from the hydraulic ram, remove the insertion mechanism, and remove the transducer pusher.
11. Thread the flameproof junction box onto the end of the transducer with the BNC connector. Ensure that at least
five full threads are engaged.
12. Connect the cable from the meter to the transducer within the junction box and install the junction box cover.
SHOCK HAZARD!
13. Repeat the above steps for any additional T11 transducers that are required to complete the installation.
