  • Page 49 Chapter 4. Inserting T17 Transducers into the Pipe 4.2.2 Mounting the Insertion Mechanism (cont.)  Visually inspect the transducer to make sure the top Swagelok fitting is not loose.  IMPORTANT: The stop ring at the end of the barrel is supposed to be loose. DO NOT tighten the Swagelok fitting or you could change the transducer alignment.
  • Page 50 Chapter 4. Inserting T17 Transducers into the Pipe 4.2.2 Mounting the Insertion Mechanism (cont.) Retract the barrel from the packing gland so that the transducer head is recessed in the packing gland. You will hear the stop ring click when the transducer is fully recessed.
  • Page 51 Chapter 4. Inserting T17 Transducers into the Pipe 4.2.2 Mounting the Insertion Mechanism (cont.) Lift the gasket and insert the packing tool into the packing nut. Turning the packing tool clockwise, tighten the packing material so that the barrel stays up without support.
  • Page 52 Chapter 4. Inserting T17 Transducers into the Pipe 4.2.2 Mounting the Insertion Mechanism (cont.) Identify the upstream and downstream transducer assemblies. For Standard Velocity Range applications, the upstream and downstream nozzle designations are interchangeable. The system is bi-directional. For Extended Velocity Range applications, the system is not bi-directional. Note which valve is designated upstream and downstream on the pipe.
  • Page 53 Chapter 4. Inserting T17 Transducers into the Pipe 4.2.2 Mounting the Insertion Mechanism (cont.) 10. Lift the insertion mechanism by the barrel and place the insertion mechanism on the isolation valve. 11. Line up the flange holes and bolt the packing gland to the isolation valve.
  • Page 54 Chapter 4. Inserting T17 Transducers into the Pipe 4.2.2 Mounting the Insertion Mechanism (cont.) 12. Using the packing tool, tighten the packing nut again until the nut is recessed. WARNING! The packing material must be securely packed before the isolation valve is opened.

  • Page 55: Aligning The Downstream Transducer For Extended Range Installations

    Chapter 4. Inserting T17 Transducers into the Pipe 4.2.3 Aligning the Downstream Transducer for Extended Range Installations For extended velocity range applications, the head of the downstream transducer is angled at 6° so that it points upstream (into the flow) by 6°. This allows the ultrasonic signal to be pushed into alignment at very high flow rates. At low flow rates, the beam is wide enough to tolerate the initial 6°...
  • Page 56 Chapter 4. Inserting T17 Transducers into the Pipe 4.2.3 Aligning the Downstream Transducer (cont.) The primary method for ensuring that the angled transducer head is pointing in the correct direction uses the alignment marks on the downstream nozzle and the downstream Barrel assembly (see the figure below). The alignment marking on the flange at the top of the Barrel must be in alignment with the nozzle, such that the marking falls between the bolt holes straddling the upstream to downstream centerline, as shown below.
  • Page 57 Chapter 4. Inserting T17 Transducers into the Pipe 4.2.3 Aligning the Downstream Transducer (cont.) Before proceeding, verify that the valve and insertion mechanism are fully bolted in place. Each stud should extend far enough beyond its nut to allow the alignment tool to rest on the stud. Fit the alignment fixture over the nozzle studs so that the two studs straddling the centerline on the nozzle are inserted into the holes on the fixture of the corresponding flange size and rating (3”, 150# or 300#).
  • Page 58 Chapter 4. Inserting T17 Transducers into the Pipe 4.2.3 Aligning the Downstream Transducer (cont.) Place the alignment fixture over the two studs in the flange at the top of the barrel assembly, and rotate the barrel flange until the bubble aligns between the tick marks on the vial. Slowly press the flange toward the insertion mechanism flange until the gasket and raised faces of both flanges are mated.

  • Page 59: Connecting An Xamp

    Chapter 4. Inserting T17 Transducers into the Pipe Connecting an XAMP This section explains how to correctly install and assemble an XAMP into a transducer junction box. Although one type of junction box is used as an example in the steps below, the procedure applies to all three possible junction box options (refer to drawing #752-063, Figure 16 on page 51).
  • Page 60 Chapter 4. Inserting T17 Transducers into the Pipe Connecting an XAMP (cont.) With the transducer and the cable gland assembled, the junction box should now look like Figure 10 below: Figure 10: Assembled Transducer and Cable Gland First, connect the right-angle male BNC plug to the exposed BNC cable from the cable gland assembly, as shown in Figure 11 below.
  • Page 61 Chapter 4. Inserting T17 Transducers into the Pipe Connecting an XAMP (cont.) Connect the female BNC plug of the XAMP to the male BNC transducer head, as shown in Figure 12 below: Figure 12: Female Plug to Male BNC Head Wrap the extra length of cable around the perimeter of the junction box such that the BNC heads do not rest on other cables or on each other.
  • Page 62 Chapter 4. Inserting T17 Transducers into the Pipe Connecting an XAMP (cont.) Place the XAMP body into the junction box (see Figure 14 below), resting the puck gently on the cables below it. Ensure that the cables of the XAMP rest naturally according to the slant at which they exit the epoxy, to reduce stress and strain on the joint.
