2.4.2 Transducer Mounting Instructions
1. Drill a 24mm diameter hole at the measuring point. Be sure to center of the hole is aligned to match
the location for the center of the transducer. Weld the coupling adapter in place.
2. Close the ball valve and screw it tightly on the mounting base.
3. Twist off the lock-nut and loosen the locking ring. Pull the transducer into the joint nut and screw
the joint nut onto the ball valve.
4. Open the ball valve and insert the transducer. Measure the dimension from the outer surface of the
pipe to the front-end surface of the handspike position to meet the following formula:
H = 216 − d
1
− d
2
H = mounting height (mm) d
1
= pipe wall thickness (mm) d
2
= pipe liner thickness (mm)
If there is no liner, d
2
= 0
5. Attach the lock ring to the joint nut by fitting its pinhole in the locating pin. Tighten the screw
slightly and turn the orientation handle until it points at the middle position between the two
transducers and its axes match the axes of the pipeline. Finally, tighten the locking screw and screw
the locating sleeve onto the joint nut.
6. Connect the transducer cables to the corresponding upstream/downstream (upstream = red,
downstream = blue) terminal ends
