Y/N
The values shown are in decimal and the test keys on Power Level 2 (P2). A successful
test and sensor target placement is achieved when the P2 value is 60 or greater.
*After completing the sensor background test, determine if another alcohol cleaning is
needed on the register face prior to installation of the sensor.
Sensor Flap
Within each case of FIREFLYs, 24 rubber Sensor Flaps are included for every
installation. Utilizing these Sensor Flaps insures a stable environment during the
calibration process.
Sensor Placement
1. Insert sensor cable through sensor flap.
2. Remove the adhesive backing from the high-bond tape on the Optic Sensor face.
3. Install sensor to the location of the best background according to the background
check.
4. 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 that
are to be in line with the needle when it passes.
5. Attach the sensor to the water meter lens
surface.
6. Since the 3M tape provides a pressure
sensitive seal, the installer must apply
15 lbs. of pressure to the MIU sensor
immediately after attaching to the lens
surface. The next step is to maintain
constant pressure for a minimum of 60
seconds.
Tip: Palm the sensor and lean
onto it to apply the
appropriate pressure.
