Duct / Flow Meter


Flow Meter Entrance LengthsNOTE:Design for seawater flow pattern in round ducting. Flow meters without moving parts (i.e. acoustic or electromagnetic - if installed) are only accurate if a “fully developed" flow is present at the point of the determination. A straight section of ducting is necessary to provide this. The graph predicts the length required for a 10” diameter duct mixing section.?
