When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases An orifice plate is a thin metal disc with a precisely sized hole, installed inside a pipe to measure how fast a fluid is flowing A little downstream of the orifice the flow reaches its point of maximum convergence, the vena contracta (see drawing to the right) where the velocity reaches its maximum and the pressure.
How does an Orifice Measures Flow? - Instrumentation Tools
Measure, throttle, and regulate the flow of liquids and gases in your line by adding an orifice plate to these unions
They consist of two flange halves, plus all of the.
Learn the different types of orifice plates, their design features, working principles, and industrial applications in flow measurement. An orifice plate is a thin, flat piece of metal with a precisely machined hole in the middle This hole, or orifice, is designed to create a pressure drop in the flow of a. An orifice plate is a thin, flat plate with a precisely machined hole (the bore) installed in a pipeline, typically between two flanges
