Abstract
An improvement in a vapor recovery line in the form of a vortex shedding flow meter installable within such vapor recovery line to monitor the flow rate of vapor being returned through the vapor recovery line, such flow meter including a housing having an inlet flange with an associated inlet connectable to the upstream portion of the vapor recovery line, an outlet flange with an outlet connectable to the downstream portion of the vapor recovery line, a housing for a passageway extending between the inlet and outlet, with a vortex strut extending into the passageway nearer the outlet to generate shed flow vortices and a transmitter-receiver transducer pair positioned nearer the outlet to subject the shed vortices to a sonic beam to effect modulation thereof, and an electronics package within an electronic housing portion for determining from such modulation the flow rate of the vapor passing through the vapor recovery line.
