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 needs to
apply pressure to the MIU sensor
immediately after attaching to the lens
surface. The next step is to apply four,
5-second pushes to the MIU.
Tip: Palm the sensor and lean
onto it to apply appropriate
pressure.
7. A full cure on the seal is achieved in 24 - 96 hours. Do not touch, pull, move, or
handle the sensor in any way during this period.
