Page 10: Installing T8 Transducers
Chapter 1. Installation Installing T8 transducers The pressure mechanism is a piston-driven hydraulic pump used for inserting T8 transducers into pressurized pipelines. To perform this procedure safely, you must follow all the instructions in this chapter very carefully.Fi 1.3.1 Equipment needed To properly install the T8 transducers, you must provide the following items: •... - Page 11 Chapter 1. Installation Using the calculated H value, mark two crosshairs on the pipe where you intend to weld the transducer ports, so that the distance between the two marks equals the H value (see Figure 2 below). IMPORTANT: Port locations should NOT be located directly on the top or bottom of the pipe. Place the ports at between 15 degrees and 90 degrees from the vertical plane of the pipe.
- Page 12 Chapter 1. Installation WARNING! Only qualified personnel should weld bosses and nozzles, using a suitable ASME IX qualified welding procedure. Weld the 2 in., schedule 80 nozzles with pipe flanges to the two marked locations on the pipe. Be careful to maintain perpendicularity and parallelism as shown in Figure 3 below.

Page 17: Positioning The Transducer
Chapter 1. Installation 1.3.4 Positioning the transducer Complete the steps in this section to position the T8 transducer in the hot-tapped port. Note: Keep the cover for the safety collar loosely around the transducer to allow for proper alignment. Measure the transducer length (“DD”) from the center of the transducer head to the end of the BNC connector. Figure 12: Measuring the transducer length Make sure the transducer head is fully retracted into the Low Pressure Assembly (LPA). - Page 18 Chapter 1. Installation Rotate the transducer barrel until the transducer face points in the general direction of the other port. Then, tighten the locking collar screws with a torque wrench to fasten the transducer in place. Use the maximum torque shown in Figure 14 below, but do not overtighten the screws.
- Page 19 Chapter 1. Installation Bolt the LPA mechanism to the 2 in. flanged ball valve, as shown in Figure 16 below. Figure 16: Bolting the LPA mechanism to the ball valve Model T8 Installation Guide...
- Page 20 Chapter 1. Installation Measure the “A” dimension, which is the distance from the outside surface of the pipe wall to the end of the BNC connector on the transducer (see Figure 17 below). Then, calculate the insertion distance (“I”) by using the following equation: –...
- Page 21 Chapter 1. Installation Mark the insertion distance on the shaft of the transducer, using one layer of colored electrical tape around the circumference so that the ends overlap (see Figure 18 below). Alternatively, apply any mark that is waterproof and easily identifiable.

Page 22: Attaching The Hydraulic Cylinder
Chapter 1. Installation 1.3.5 Attaching the hydraulic cylinder The next step in the transducer installation process is to attach the hydraulic cylinder to one of the transducer ports. Install the connector protector on the 1/2” NPT thread of the transducer shaft until it is finger-tight (see Figure 19 below). - Page 23 Chapter 1. Installation Refer to Figure 20 below and attach the hydraulic cylinder to the four studs of the LPA with four 3/8-16 hex nuts. Tighten the nuts to a maximum torque of 19 ft-lb (25 N-m). IMPORTANT: If the piston of the hydraulic cylinder touches the connector protector before the hydraulic cylinder can seat properly onto the studs, remove the hydraulic cylinder from the LPA.
- Page 24 Chapter 1. Installation Refer to Figure 21 below and attach the hose of the hydraulic pump to the hydraulic cylinder at the pipe coupler. Note: The 2 in. ball valve should be closed and the locking collar should be tightly secured to the transducer shaft. Figure 21: Attaching the hydraulic cylinder Model T8 Installation Guide...

Page 25: Inserting The Transducer
Chapter 1. Installation 1.3.6 Inserting the transducer After attaching the hydraulic cylinder, you are now ready to insert the T8 transducer. To prepare for pumping, rotate the side knob of the hydraulic pump clockwise to tighten it (see Figure 22 below). Slowly pump the handle of the pump until you feel resistance, then stop pumping. - Page 26 Chapter 1. Installation There are four 10-32 x 3/4 socket head screws and two 1/4-20 x 1 3/8 socket head screws on the locking collar (see Figure 23 below). Evenly loosen these screws. just enough so that the transducer can move freely. Figure 23: Loosening the socket head screws Before opening the ball valve do the following: •...
- Page 27 Chapter 1. Installation Slowly open the 2 in. ball valve and check for gas leaks: • If you discover any leaks, close the ball valve and fix the leaks. • If you do not detect any leaks, proceed to the next step. See Figure 24 below and slowly pump the hydraulic pump handle until the transducer moves to the pre-marked insertion depth, as indicated by the edge of the electrical tape touching the edge of the locking collar.

Page 28: Adjusting The Safety Alignment Collar
Chapter 1. Installation 1.3.7 Adjusting the safety alignment collar The next step in the transducer installation procedure is to adjust the safety alignment collar. Locate the safety alignment collar that was shipped with the T8 transducer. Use an Allen wrench to remove the two socket head cap screws and the set screw from the safety alignment collar (see Figure 25 below). - Page 29 Chapter 1. Installation Slide the safety alignment collar into the safety collar cover and position both collars so that they are touching the safety plate (see Figure 27 below). Note: If necessary, adjust the height of both screws on the safety collar cover to allow the safety alignment collar to fit into it.

Page 30: Removing The Hydraulic Cylinder
Chapter 1. Installation 1.3.8 Removing the hydraulic cylinder The final step in the T8 transducer installation process is the removal of the hydraulic cylinder from the port. Verify that the screws on the locking and safety alignment collars are tightened to the appropriate torque. Then, very slowly turn the side knob of the hydraulic pump counterclockwise to release the pressure of the hydraulic cylinder on the transducer shaft (see Figure 29 below). - Page 31 Chapter 1. Installation See Figure 30 below and remove the hydraulic cylinder by unscrewing the four 3/8-16 stainless steel hex nuts. Figure 30: Removing the hydraulic cylinder Unscrew and remove the connector protector (see Figure 30 above). Note: Disconnecting the hydraulic pump at the quick-disconnect pipe coupler simplifies the hydraulic cylinder removal.
- Page 32 Chapter 1. Installation Attach the pipe adapter to the 1/2” NPT thread of the transducer, and then attach the junction box to the pipe adapter. Use a wrench on the flats of the transducer body to prevent transducer rotation when installing the junction box (see Figure 31 below).

Page 33: Resetting Or Storing The Hydraulic Cylinder
Chapter 1. Installation Resetting or storing the hydraulic cylinder To prepare the hydraulic cylinder for its next use or for storage, you must retract the piston. Remove the safety pin and attach the guide for the push rod to the hydraulic cylinder with four 3/8-16 hex nuts (see Figure 32 below). - Page 34 Chapter 1. Installation Turn the side knob of the hydraulic pump counterclockwise to release the oil pressure (see Figure 34 below). Figure 34: Releasing the oil pressure Hold the cylinder with one hand, and push the rod with the other hand until the piston bottoms out inside the cylinder (see Figure 35 below).
- Page 35 Chapter 1. Installation Position the 0.28 in. diameter hole of the push rod to align with the 0.28 in. diameter hole of the push rod guide. Then, push the safety pin through the holes to secure the cylinder, push rod and push rod guide assembly (see Figure 36 below).
