Weldment Installation
Note: Ensure that the mounting location meets the requirements for uniform water flow.
Refer to Flow Sensor Location on Page 44-45.
Note: Ensure that there is enough room for the weldment, sensor and connector to fit.
Refer to Figure 46.
1. Drill and deburr a 1 11 /
16
" to 1 3
/
4
" diameter hole at mounting location.
2. Center weldment mount over hole and weld it to pipe. The weld must be continuous around the fitting
with no gaps or voids.
3. Screw sensor housing into weldment. Run it down far enough to make sure it will go through the pipe
freely then back it out.
Note: The paddlewheel sensor must be correctly aligned in the water stream. The alignment
tab is used to set the position of the sensor. Make sure that the alignment tab is centered on
the pipe centerline.
Refer to Figure 46.
4. Set sensor housing to dimension A in Figure 46. Make sure the alignment tab is centered on the pipe
as shown (it can be on upstream or downstream side).
5. Screw on tru-seal locknut and tighten with a 2" wrench using light to medium torque. Make sure that
the sensor housing alignment tab remains centered and the sensor housing does not rotate causing
dimension A to change.
6. Insert flow sensor into sensor housing. Align flat spot on sensor rim with alignment tab and make sure
o-ring is in groove.
Note: The retainer cap only needs to be hand tightened. There is an inside lip that will stop the cap
from turning when it makes contact with the alignment tab. This provides the correct pressure to
make the seal at the o-ring. Make sure the flow sensor does not disengage from the alignment tab
and rotate.
7. Install retainer cap and hand tighten.
8. Connect cable from display module to flow sensor (the cable is color coded blue).
Refer to Wiring section on Page 68.
