above-ground generally transmit the greatest distance.
2. The material of a pit or vault lid affects the transmission range. For example, a
transmitter has a greater range sending from a pit with a plastic lid than a cast iron
lid.
3. Lids with holes of a diameter of one inch make possible the mounting of the
FIREFLY
MIU through the lid. This can increase transmission range significantly.

5. If the lid has a hole for the unit, use the
cap and wing nut assembly (“lid lock”
pictured below). Ensure that enough
space exists between the box lid and
the ground for the unit to sit. If not,
remove some of the dirt from the
bottom of the box. Do not over-tighten
lid locks.

Meter Preparation
1. Remove meter box lid.
2. Survey the meter, checking lid, hole depth, and overall cleanliness.
3. Check for meter disqualification’s and enter the corresponding skip code.
4. Check for potential meter problems and enter the corresponding trouble code.
5. Clean excess dirt from meter lid, exposing meter number.
6. Flip lid back and pre-clean meter face/lens using Fast Orange non-pumice cleaner
and a cloth or cotton swab to remove residue.
7. Clean meter face/lens with an isopropyl alcohol and a
Note: Use Isopropyl rubbing alcohol, 99% by volume, for best results.
Lower concentrations do not clean as well and adversely affect the
sensor-to-meter bond.
8. 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.
9. After cleaning, ensure that the lens is

Power 3 [66]
Status: [Success]
Test Again?
Y/N
The values shown are in decimal. Two out of three need to be between 32 and 96.
Status will display as Success or Failed.
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.
Since the 3M tape provides a

, the installer needs to
apply pressure to the MIU sensor
immediately after attaching to the lens
surface. The next step is to apply four,

pressure.
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.

8. Apply approved adhesive around the sensor to seal it completely if the pit fills with
water prior to the 24 - 96 hour cure time, or if the meter face is curved and not flat.
Note: If the sensor is initially misplaced, do not attempt to remove the
sensor by twisting the sensor body. A fully cured sensor requires
breaking the seal at the adhesive tape joint with a flat tool such as a
screwdriver. Insert the screwdriver between the aluminum base and
meter lens and twist.
9. Mount the
FIREFLY
box/vault lid.
If using a stake, affix the stake in the ground adjacent to the meter register. The
platform area of the pole needs to face inward.
Position the transmitter on the pole platform.
Attach the transmitter to the pole with the binding material.
If utilizing a lidlock, make certain Not to overtighten the FIREFLY within the lock.
Also be sure to never rest the weight of the lid on the FIREFLY.
10. Place sensor flap over sensor, insuring a snug fit.
11. Program the MIU and set to "Autocal".
12. Before closing the lid, make sure a visual meter reading is entered for the account.
Note: At this point, if sensor flap must be lifted to retrieve the visual
meter reading, AutoCal must be reset through the FIREFLY menu #7.

2. Connect
FIREFLY
wire-end to meter contacts using Posi-lock connector or Gel caps.
3. Use 3M mastic pads to cover the wire connections. Ensure that the mastic pad forms
a complete seal around the wire connections.
4. Mount the
FIREFLY
to an appropriate wall, stake, or through hole in the meter box /
vault lid.
5. If using a stake, affix the stake in the ground adjacent to the meter register. The
platform area of the pole needs to face inward.
6. Position the transmitter on the pole platform.
7. Position the
FIREFLY
MIU with the threaded neck pointing up.
8. Attach the transmitter to the pole with the binding material.
Note: Do not connect a multi-meter, probe or other interrogating device
FIREFLY
to the
wires. Doing so may cause the unit to globally reset,
erasing all programmed data!
