Abstract
A flow meter is provided for measuring the flow rate of fluid through a conduit having an inlet and an outlet, which includes a measuring chamber having a float disposed therein for movement in response to fluid flow, and a detector for detecting the movement of the float in the measuring chamber. Various devices are provided for controlling the path of fluid flow from the conduit outlet to the conduit inlet, which includes apparatus for allowing fluid to flow from the outlet through the measuring chamber in a first direction so as to move the float in the first direction past the detector, and for also allowing fluid to flow from the outlet through the measuring chamber in a second direction so as to move the float in the second direction past the detector. Apparatus is connected to the detector for measuring the rate of fluid flow in response to the movement of the float in the first and second directions.
