D4100 MOSAIC Meter Interface Unit (MIU)
The D4100 MOSAIC Meter Interface Unit (MIU) tracks and transmits meter reading 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.
Battery: 3.6-volt lithium chloride D-cell
Material: Polycarbonate
Construction: Ultrasonic welding
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
• Leak Detection
• Tamper Detection
• Battery Status Indicator
