FIREFLY INSTALLATION
INSTALLING THE OPTICAL SENSOR
MIU Preparation
1. Survey the meter, checking lid, hole depth, and overall cleanliness.
2. Remove meter box lid.
3. Clean excess dirt from meter lid, exposing meter number.
4. Flip lid back and pre-clean meter face / lens using Fast Orange non-pumice cleaner
and a cloth or cotton swab to remove residue.
5. Clean meter face / lens with an isopropyl alcohol and a NEW lint-free cotton swab.
Note: Use Isopropyl rubbing alcohol, 99% by volume, for best results. Lower
concentrations do not clean as well and may adversely affect the sensor-to-meter
bond.
6. Re-wipe the surface of the meter lens with a clean, new cotton swab each time
until the swab comes up clean, and the clean lens squeaks when wiped.
7. After cleaning, ensure that the lens is completely dry; allow the alcohol time to
evaporate.
MIU Placement
8. Remove the adhesive backing from the high-bond tape on the Optic Sensor face.
9. Refer to Meter Qualification Data in Appendix C to determine sensor placement for
the brand and model of register.
10. Orient the sensor so the water meter needle approaches the sensor from the cable side
and perpendicular to the cable. There are indents on each side of the sensor base
which are to be in line with the needle when it passes.
11. Attach the sensor to the water meter lens surface.
