Orifice Plates, Assembly, Concentric Orifice Plates, Quadrant

Orifice Plates. An orifice plate is a thin plate with a hole in the middle. It is usually placed in a pipe in which fluid flows. When the fluid reaches the orifice plate, with the hole in the middle, the fluid is forced to converge to go through the small hole; the point of maximum convergence actually occurs shortly downstream of the physical orifice, at the so-called vena contracta point.

Orifice plate - Wikipedia

An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice [1] : 85–86 but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases.
