Abstract
A fluid flow system and method according to which a fluid flow meter is provided that receives fluid and has an internal member that rotates in response to fluid flow through the meter. A self-contained, battery-operated sensor is disposed adjacent to, but externally of, the meter and functions to sense the rotation of the member. The sensor includes a display device that responds to the sensing of the rotation, and therefore the fluid flow through the meter, and provides a corresponding output signal. Thus, a service technician can be assured of the status of fluid flow through the system.
