Direct Mode With Ez Clamp And Spacer Bar Only - Siemens SITRANS F Operating Instructions Manual

Section 3
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 transducer 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 orienta-
tion 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 proce-
dure for the number index transducer.
