The D4100 MOSAIC System is an automatic meter reading system designed for reading meter data
remotely and wirelessly. This is accomplished using the Datamatic D4100 MOSAIC Meter Interface
Unit (MIU) that forms a mesh network with neighboring D4100 MOSAIC MIUs, and reports data to the
Home Office (HO) through strategically placed gateway devices.
The main benefits of using a D4100 MOSAIC System are:
• Real-time access to meter readings
• Built-in logging of 72+ days of consumption data
• Complete remote control of MIUs through MOSAIC Software Interface
• Meter lids do not have to be removed for reads
• Meter pits do not have to be dug out or pumped out for reads
• Increased accuracy of meter readings
• Safer meter reading procedure
• Visiting the site is not necessary for data collection
Please consult the MOSAIC Software Interface Guide for user instructions regarding data access,
configuring, or upgrading the D4100 MOSAIC. After reviewing this guide you should be able to
successfully deploy the D4100 MOSAIC for your application.
The D4100 MOSAIC Meter Interface Unit (MIU) tracks and transmits meterreading data. Each D4100
MOSAIC can be configured to record 72+ days of hourly consumption readings, thereby enabling the
resolution of billing disputes. The D4100 MOSAIC signal includes the meter number, meter reading,
battery voltage, tamper flag, and a leak indicator.
Operating Temperature Range: -40°F to 185°F
Radio Communication Frequency: 902 - 928 MHz
D4100 MOSAIC – Optic Sensor-end
This D4100 MOSAIC uses an optical sensor unit to track meter activity. The infrared sensor is oriented
so that the register needle approaches the sensor from the cable side and perpendicular to the cable. The
indicators on the top side of the sensor need to be aligned with the passing sweep hand. As the needle
sweeps past the sensor, it changes the light reflected back from the meter face, and an incremental count
is registered. The optical sensor is affixed to the meter face using a high-bond adhesive tape.
Unique Features:
• Use existing meters.
• The D4100 MOSAIC Optic Sensor Model is the only available technology for automating
meters without electronic registers
• Ultrasonically-welded, seamless construction designed to withstand constant submersion
The D4100 MOSAIC for water meters installs in under five minutes on virtually any meter. Wired-end
Model D4100 MOSAIC's support all the popular pulse and encoder registers. The D4100 MOSAIC
eliminates the need for meter changeout for the purpose of AMR implementation and can save utilities
millions of dollars in meters and installation labor.
Unique Features:
• Use existing meters.
• Maintain the freedom to choose meters without the constraints of proprietary AMR system.
• Ultrasonically-welded, seamless construction designed to withstand constant submersion
• Accommodates direct-read, pulse and encoded registers
• Leak Detection
• Tamper Detection
• Battery Status Indicator
• Above ground, below ground or through-the-lid installation
D4100 MOSAIC – Logical Switch
The D4100 MOSAIC Logical Switch (FFLS) represents another step
forward for the innovative D4100 MOSAIC AMR technology. The FFLS
combines the unshakeable accuracy of an absolute encoder register with the
low cost of a pulse register. It provides an instant interface to Master Meter
"high glass" and similar registers on any size meter, adding one more option
to the D4100 MOSAIC's already Meter Independent approach to
Automatic Meter Reading. The FFLS works by sensing the magnet
embedded in the register's sweep needle. Each revolution sends a signal that
increments the D4100 MOSAIC. The Logical Switch also tracks
REVERSE rotations (backflow)! D4100 MOSAIC readings remain 100%
accurate even under less-than-ideal line conditions. Installation takes only
seconds using a standard screwdriver.
D4100 MOSAIC Logical Switch on Master Meter
Unique Features:
• Encoder performance without the cost
• Interfaces to Master Meter "high glass" and similar registers - all meter sizes
• Tracks forward and reverse flow with 100% accuracy
• Connects directly to D4100 MOSAIC Water MIU in less than 1 minute
• Can be ordered pre-potted to D4100 MOSAIC Water MIU
If the lid has a hole for the unit, use the cap and wing nut assembly
(“lid lock” pictured at right). 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.
1. Signal distance varies depending on the location of the D4100 MOSAIC. Those installed 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 roughly 1 3/4 inches make it possible to mount the D4100 MOSAIC through the lid. This can increase transmission range significantly.
4. Complete field installation of a D4100 MOSAIC takes 5-10 minutes, depending on the meter
location and mounting application.
5. If the lid has a hole for the unit, use the cap
and wing nut assembly (“lid lock” pictured
at right). 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-
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
register. Normally, place sensor along outer edge of register.
NOTE: Do not place the sensor over any moving part or the sweep hand of the register. Normally, place
NOTE: Since the 3M tape provides a pressure sensitive seal, the installer must apply 15 lbs. of
pressure to the D4100 MOSAIC optical sensor immediately after attaching to the lens surface for a
minimum of 60 seconds.
1. Very Important: Press the adhesive down for 60+ seconds using 15 lbs of pressure. Allow 24-96
hours to cure.
2. Fasten the cable to the register with a zip tie.
3. Place Goop-Plumber’s Adhesive #15112 (purple tube) around the metal edge sensor and under the
tail of the sensor. Do not squirt the adhesive UNDER the 3M seal. The goal is to provide a
temporary water barrier between the meter face and the metal edge of the sensor, so that the 3M
adhesive can cure properly.
4. Position the flap at the base of the sensor so that it folds over and “hangs” above the register to try to
keep most of the stray light out while it processes through AutoCAL. The flap will be “pulled” over
the sensor snuggly lying flatter on the meter during the Read and Verify procedure that will be
discussed later.
Final Optic Sensor-end D4100 MOSAIC Installation Steps
1. 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.
2. Mount the D4100 MOSAIC box with the threaded neck pointing up.
3. Mounting can be accomplished by attaching to a wall, stake, or through a hole in the meter box or
vault.
4. Typical meter pits will use an 18” long ¾” PVC stake. Push the stake into the ground approx. 6”
deep, adjacent to the meter register.
5. Attach the D4100 MOSAIC to the stake with the zip ties (6” or 14”).
6. If utilizing a lid lock, make certain not to over-tighten the D4100 MOSAIC within the lock.
7. Check for lid clearance; be sure to never rest the weight of the meter lid on the D4100 MOSAIC.
