Web10 Mar 2009 · Good Answers: 2. # 4. Re: Orifice Plate Bevelling. 03/09/2009 3:38 AM. The flow pattern resulting from the sharp edge produces pure line contact between the plate and effective flow , with negligable fluid to metal friction drag at this boundary. Any burrs or rounding of the sharp edge can result in large errors.
The simplest design of orifice plate is the square-edged, concentric orifice. This type of orifice plate is manufactured by machining a precise, straight hole in the middle of a thin metal plate. Looking at a side view of a square-edged concentric orifice plate reveals sharp edges (90ocorners) at the hole: See more The point where the fluid flow profile constricts to a minimum cross-sectional area after flowing through the orifice is called the vena contracta, and it is the area of minimum fluid … See more Square-edged orifice plates may be installed in either direction, since the orifice plate “appears” exactly the same from either direction … See more The first of this type is called the eccentric orifice plate, where the hole is located off-center to allow the undesired portions of the fluid to pass through the orifice rather than build up on the … See more Other square-edged orifice plates exist to address conditions where gas bubbles or solid particles may be present in liquid flows, or where liquid droplets or solid particles may be present in gas flows.

Orifice plates are most commonly used to measure flow rates in pipes, when the fluid is single-phase (rather than being a mixture of gases and liquids, or of liquids and solids) and well-mixed, the flow is continuous rather than pulsating, the fluid occupies the entire pipe (precluding silt or trapped gas), the flow profile is even and well-developed and the fluid and flow rate meet certain other conditions. Under these circumstances and when the orifice plate is constructed and instal… Web1 Jan 2016 · Orifice meter is a differential pressure type flow measuring device in which energy loss is a major problem.
