6. Apply a 1/8-inch continuous bead of couplant compound along the center (the long way) of
the contact surface of the transducer. Place transducer on the pipe center in the middle of
one of the areas you have cleaned with the cable connector facing away from where the
other transducer will be placed.
7. While holding this transducer in-place, bring the chain around the pipe and attach the
closest cross-link onto the hook of the EZ clamp. Tighten the adjusting nut until the chain is
just snug around the pipe. Ensure that the chain is straight around the pipe and the trans-
ducer contacts the pipe at the white dot just under the front label. Ensure that there is
equal space between the edges of the transducer and pipe.
8. Repeat Steps 5 and 6 with the second transducer leaving it still attached to the spacer bar.
Apply a 1/8-inch bead of couplant compound to the transducer. At the same time that you
place it in the middle of the second area prepared, secure the spacing bar to the already
mounted transducer by inserting the transducer index screw through the REF hole on the
Bar and into lowest hole on transducer (for those transducers that have two holes). Sight
along spacer bar to ensure axial alignment to the pipe. Adjust if necessary. Tighten both
chains. Do not overtighten. Ensure that transducers did not move while tightening.
9. Connect the transducer cable, ensuring that you have observed the upstream/downstream
orientation in respect to the cable and the input jack on the flow computer. If this is a dual-
channel unit, make sure you are connecting the cables to the correct channel’s input jacks.
Repeat this procedure for the number index transducer.
3.1.6 DIRECT MODE WITH EZ CLAMP AND SPACER BAR ONLY
This section will present an easy, uncomplicated method of mounting transducers in Direct
Mode and ensuring that they will line up exactly 180
o
from each other (9 o’clock - 3 o’clock
positions) and spaced the proper distance apart.
