Paddle flow monitoring device

摘要

A flow sensor (20) has a paddle assembly (22) that is mounted to a housing (40) by opposed pivot posts that extend from the paddle assembly between a paddle (24) and a magnet. The housing has two pivot post clips (38) that resiliently capture the pivot posts which are received in mounting holes in resilient clips. A shroud (67) surrounds the housing (40) and positions a biasing magnet (68) which repels the magnet on the paddle assembly (22). The shroud slides over the housing and provides a transverse passageway that is aligned with a transverse passageway (62) in the housing (40). An activation sensor (58) positioned within a sleeve (60) is positioned within the transverse passageway (62) in the housing and passes through a transverse passageway (64, 66) in the shroud (67) pinning the two subassemblies together. <IMAGE>
