Abstract
A fluid meter includes a casing, a lever within the casing that oscillates in response to the flow of fluid through the meter and an attachment mechanism that mounts an automatic meter reader to the casing in proximity to the lever. A magnet is attached to the lever so that movement of the lever creates a changing electromagnetic field external to the casing. The changing electromagnetic field is detected by and operates to actuate the automatic meter reader. As a result, the automatic meter reader detects fluid flow in the fluid meter without being directly connected to, or interfering with the operation of, a mechanical meter index associated with the fluid meter.
