A device (10) for monitoring utility usage comprising a meter sensor assembly (16) attached to a utility meter (14) and a customer interface unit (20) placed inside a building (12). Sensor signals from the meter sensor assembly (16) are transmitted through a reset/driver unit (18) via the cable (22) to the customer interface unit (20) where the signal is processed into usable data that is communicated by a LCD display (114) on the front face (110) of the customer interface unit (20). Rotation of the meter disk (24) is sensed by infrared light signals (82) detecting the passage of the mark (38) on the edge (32) of the disk (24). The mounting assembly (40) is easily attached to the front face (30) of the transparent case (26). The reset/driver unit (18) includes a magnetic reset switch (98) that coordinates processing of data with the monthly billing cycle of the utility.
