Flowmeter having an adjustable shield with flow scales

Abstract:

A flowmeter having an adjustable protective shield for calibrating the flowmeter is presented. The flowmeter includes an inner conduit providing a flow path for pressurized fluid, a protective shield having a plurality of markers providing a visible indicator of the flow rate of the pressurized fluid according to the position of the float in the flow path, and a housing assembly for receiving the inner conduit and the protective shield. The flowmeter also can include a fitting assembly for securely coupling the inner conduit, the flow label, and the housing assembly in-line within a pipeline path. The flowmeter can be calibrated by adjusting the position of the protective shield while in-line within the pipeline path.
