Installation Procedures

Installation Overview for Water D4100 MOSAICs

1. Perform a site survey to determine where best to install the Gateway devices and where to

designate MIU mesh network areas.

2. Configure MIUs before on site installation with the unique mesh word to form a group of

selected MIUs into a mesh network.

3. Prepare the meter.

4. Attach the D4100 MOSAIC.

5. Using a mobile gateway, take a reading to verify neighbor MIUs on the mesh.

6. Once the entire route is installed, verify connectivity from the installed gateway to the Home

Office.

#1 Preparation Of the Meter

1. Remove meter box lid.

2. Survey the meter, checking lid, hole depth, and overall cleanliness.

3. Check for meter disqualification.

4. Place sensor flap onto D4100 MOSAIC cable.

5. Flip lid back and pre-clean meter face/lens using Fast Orange non-pumice cleaner and a cloth or

cotton swab to remove residue.

6. Clean meter face/lens with 99% isopropyl alcohol and a NEW lint-free cotton swab.

7. 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.

8. After cleaning, ensure that the lens is completely dry; allow time for the alcohol to evaporate.

NOTE: Only use isopropyl rubbing alcohol marked “99% by volume”. Lower concentrations, such as

the commonly available 91%, do not clean or evaporate well and adversely affect sensor-to-meter bond.

#2 Placement of the Sensor

1. Insert sensor cable through sensor flap.

2. Remove the adhesive backing from the high-bond tape on the optic sensor face.

3. 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. Do not place the sensor over any moving part or the sweep hand of the

NOTE: Do not place the sensor over any moving part or the sweep hand of the register. Normally, place

sensor along outer edge of register.
