Abstract: The present invention achieves technical advantages as an AMR device adapted to couple to utility meters and detect an excess rate of product delivery and responsively generate an alert indicative of this excess rate. Advantageously, the alert is provided to a remote device to provide notice of an abnormal condition, such as a leak which could produce flooding, or customer exceeding an allowed delivery rate, such as during conservation periods.

Abstract: The present invention achieves technical advantages as an AMR device and method of use having an optical transceiver adapted to read analog meter faces. The transceiver advantageously includes an optical receiver having an amplifier receiving signals from photodiodes and further including an automatic gain control. A gain of the optical receiver amplifier is programmable to compensate for parameters affecting the photodiodes in the optical receiver.

Abstract: The present invention provides a device, system, and method for detecting and measuring the bi-directional flow of a fluid through a fluid meter, such as a household or business water meter. In one device embodiment the invention comprises a logical switch collar (12) disposed over an analog fluid meter (14) having a sweep-hand (18) with a magnet (16) coupled thereto. In operation, the logical switch collar (12) consists of at least two magnetic switches that are triggered to open or close in response to the rotational movement of the sweep-hand (18) as fluid flows through a fluid meter (14) in both the forward and reverse directions. These switching events are detected and recording by an electronic module (19). Advantageously, the present invention accurately monitors and records fluid consumption at predetermined intervals when the fluid flows through the meter in either direction (14).
