Abstract
A fluid meter includes a housing which comprises a cavity that defines a flow bore through which a fluid to be metered is directed, a rotor which is rotatably supported in the cavity and is set into rotation by the fluid flowing through the flow bore, a first magnet which is connected to the rotor, a second magnet which is magnetically coupled to the first magnet, a cap member which is positioned over the first magnet and separates the second magnet from the cavity, and a rotary encoder which is operatively coupled to the second magnet. Rotation of the rotor is magnetically transmitted through the cap member from the first magnet to the second magnet and is detected by the rotary encoder.
