Abstract
A fluid flow meter includes a fitting attachable to a waterworks valve or pipeline so as to extend at least partially through an insertion aperture thereof. A measurement cylinder is pivotally attached to the fitting, and includes a fluid vortex generating obstruction. A sensor body extends through the fitting and has a sensor element at an end thereof disposed in the measurement cylinder and generally aligned with the obstruction to detect fluid vortices generated by the obstruction. The measurement cylinder is selectively movable from a position generally aligned with the fitting, to a position generally parallel to the fluid flowing through the valve or pipeline.
