Chapter 2: Installation RouteSTAR FIREFLY Version 2.4 Datamatic.com, Ltd. 2000 – 2002 1WATER FIREFLY INSTALLATION PREPARATIONInstallation Overview - Sensor End1. Install the optical sensor. (See instructions “Installing the Optical Sensor”).2. Program the FIREFLY MIU (See instructions “Programming the FIREFLY MIU”).3. Choose a method and mount the FIREFLY MIU.4. Verify that the FIREFLY MIU is transmitting properly.Installation Considerations1. Signal distance varies depending on the location of the MIU. FIREFLYs installedabove ground generally transmit the greatest distance.2. The material of a pit or vault lid affects the transmission range. For example, atransmitter 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 theFIREFLY MIU through the lid. This can increase transmission range significantly.4. Complete field installation of an MIU takes 5-10 minutes, depending on the meterlocation, and mounting application.5. If the lid has a hole for the unit, use the cap and wing nut assembly (lid lock). Makesure there is enough space between the box lid and the ground for the unit to sit. Ifnot, remove some of the dirt from the bottom of the box. Do not over-tighten lidlocks.Installation TipsFollowing are tips for FIREFLY installation that ensure maximum adhesion.1. Use only 99% Isopropyl alcohol to prepare the meter face.2. The most important part of installing a FIREFLY sensor on a clean register is thePressure step.3. Make sure the lens is clean and dry as condensation reduces adhesion.4. Cool weather may reduce adhesion. Avoid installing sensors in temperatures lowerthan 32F.5. Only use the specified 3M adhesive disks to adhere the sensor to the meter face.6. Do not to touch the 3M adhesive with bare hands, as skin oil greatly decreasesadhesion.7. Adhesion is greatly degraded if the sensor is removed from the meter face thenrepositioned.8. Loctite adhesive forms a barrier around the 3M adhesive for the 24-hour curing time.9. Avoid handling or moving the sensor after placement while mounting the FIREFLY.
RouteSTAR FIREFLY Chapter 2: Installation2 Datamatic.com, Ltd. 2000 – 2002 Version 2.4FIREFLY INSTALLATIONINSTALLING THE OPTICAL SENSORMIU Preparation1. 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 cleanerand 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. Lowerconcentrations do not clean as well and may adversely affect the sensor-to-meterbond.6. Re-wipe the surface of the meter lens with a clean, new cotton swab each timeuntil 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 toevaporate.MIU Placement8. 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 forthe brand and model of register.10. Orient the sensor so the water meter needle approaches the sensor from the cable sideand perpendicular to the cable. There are indents on each side of the sensor basewhich are to be in line with the needle when it passes.11. Attach the sensor to the water meter lens surface.
Chapter 2: Installation RouteSTAR FIREFLY Version 2.4 Datamatic.com, Ltd. 2000 – 2002 312. Since the 3M tape provides a pressure sensitive seal, the installer should applypressure to the MIU sensor immediately after attaching to the lens surface. Theinstaller should apply four, five-second pushes to the MIU.TIP: Palm the sensorand lean onto it toapply appropriatepressure.13. A full cure on the seal is achieved in 24 hours. The sensor should not be touched,pulled, moved, or handled in any way during this period.Apply approved adhesive around sensor to seal completely if the pit may fill withwater prior to the 24-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 bytwisting the sensor body. A fully cured sensor requires breaking the seal at theadhesive tape joint with a flat tool such as a screwdriver. Insert the screwdriverbetween the aluminum base and meter lens and twist.14. Mount the FIREFLY MIU to an appropriate wall, stake or through hole in meterbox/vault lid.If using a stake, affix the stake in the ground adjacent to the meter register. Theplatform area of the pole should be facing inward.Position the transmitter on the pole platform.Attach the transmitter to the pole with the binding material.Re-mounting the 3M sensorFor instructions on re-mounting the FIREFLY sensor once placed on the meter, seeAppendix D: Reference, in the section titled “Re-application of Sensor 3M Tape”.

Refer to Appendix C : Meter Qualification to determine wire connection for the brandand model of meter.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. Make sure mastic pad forms acomplete seal around the wire connections.4. Mount the FIREFLY to an appropriate wall, stake, or through hold in the meter box /vault lid.If using a stake, affix the stake in the ground adjacent to the meter register. Theplatform area of the pole should be facing inward.Position the transmitter on the pole platform.5. Position the FIREFLY MIU with the threaded neck pointing up.6. Attach the transmitter to the pole with the binding material.Note: Do not connecta multi-meter, probeor other interrogatingdevice to theFIREFLY wires.Doing so can causethe unit to globallyreset, erasing allprogrammed data!
