1.0 Focus TM Probe Pipe Fitting Installation The instructions that follow are for installing the necessary fittings that will support the Focus TM Probe flow meter. Figure 1 shows the components and may be used as a visual reference while installing the fittings. The Focus TM Probe must never be installed in a vertical position where debris or moisture is likely to settle on the optics. When installing into horizontal runs, position the fittings so that the probe will be inserted at the 3 o’clock position.
2.0 Focus TM Probe Pipe Fitting Installation – Hot Tap 1. 2. 3. 4. Choose the location in the pipe that you want to install the Focus TM Probe. Install a Threadolet with a 1” NPT thread. Apply an appropriate pipe sealant and thread the 1” to 1” Nipple into the Threadolet and tighten. Apply an appropriate pipe sealant and, holding the Ball Valve so the mounting holes and lever point away from the pipe, thread the 1” Ball Valve on to the Nipple and tighten.
SUPPORT SLEEVE PACKING GLAND HOT TAP TOOL Figure 3: Inserting the support sleeve 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. Slide the Support Sleeve onto the Hot Tap Tool so the sleeves threads are toward the pipe as shown in Figure 3. Apply an appropriate pipe sealant and thread the Packing Gland into the Ball Valve and tighten.
3.0 Focus TM Probe Installation The instructions in this section cover the installation of the Focus TM Probe and the safety hardware used to retain the probe. Figure 4 through Figure 6: Insertion Depth Calculations for 4" and Smaller Pipe Diameters provide visual aids for the installation procedures. At no time during the installation should any person position any part of their body in line with the probe. A pressurized pipe could cause the probe to accelerate outwards causing bodily harm.
3.2 Procedure – Calculating Insertion Depth – 6” and Larger Pipes: Before progressing with the installation of the probe it is necessary to calculate and mark the correct insertion depth. The actual measuring point for the Focus TM Probe is 1.65” (42mm) from the end of the probe. For 6” and larger pipe diameters this measuring point should be positioned at the quarter radius point of the pipe for accurate readings. This is calculated using the following method.
3.3 Procedure – Calculating Insertion Depth – 4” Pipe: Before progressing with the installation of the probe it is necessary to calculate and mark the correct insertion depth. The actual measuring point for the Focus TM Probe is 1.65” (42mm) from the end of the probe. For a 4” pipe diameter this measuring point should be positioned at the center point for accurate readings. This is calculated using the following method. Refer to Figure 5 for a diagram of the measurements to be taken. 1. 2. 3.
3.4 Procedure – Installing the Focus 1. 2. 3. 4. 5. 6. 7. 8. 9. TM Probe: Ensure the Ball Valve is in the OFF position. (Handle perpendicular to Ball Valve as shown) Loosen the Packing Gland Nut to allow the probe to slide through. Slide the probe through the Packing Gland until it gently rests against the closed ball valve. (An o-ring in the packing gland will seal against the probe body) Connect the Quick Link and Safety Chain to the Safety Chain Clip. Adjust length of Safety Chain until it is tight.

Line up the four pins and connect the Heater Receptacle to Supply Cable NOTE: Optional heated window for wet processes.
4.0 Focus TM Probe Removal At no time during the removal should any person position any part of their body in line with the probe. A pressurized pipe could cause the probe to accelerate outwards causing bodily harm. Ensure safety chain is attached to prevent blow out. Small leakages may occur during removal. Take appropriate safety precautions. Remove only under minimal operating pressure or with the line shut off to prevent large forces acting on the probe. (Refer to section 3.
5.0 Focus TM Probe Maintenance 1. Check that alignment scribe marks are present on the flow meter as shown in Figure 13. NOTE: Ensure that scribe marks are aligned and that L2 is toward the tip on reassembly. Alignment Scribe Marks. Figure 13: Alignment Scribe Marks on Insertion Probe Components 2. 3. 4. Disassemble the 3 main components of the flow meter as shown in Figure 14 by unscrewing counterclockwise. Inspect o-rings for wear and cracks and replace as necessary.
5. Inspect optical surfaces shown in Figure 15 for fouling and clean using alcohol, a clean cloth and a q-tip. Figure 15: Carefully Clean Optical Surfaces With a Clean Cloth and Q-Tip 6. Reassemble probe components ensuring that the shorter portion of the center piece is towards the tip of the flow meter as shown in Figure 13. Use a removable threadlocker on threads. !!ENSURE SCRIBE MARKS LINE UP ON REASSEMBLY!! 14 Making Light Work ~ Photon Control Inc.
