Orifice Plates

Orifice plates are frequently employed when a pump supplies a greater pressure than what is needed by a system. In such cases, an orifice plate is installed in the discharge line to create backpressure, which guarantees that the pump functions within its optimal range. Orifice plates can also be utilized to regulate flow. The orifice plate directs the liquid or gas whose flow rate is to be assessed, resulting in a pressure drop across the plate that fluctuates according to the flow rate. This differential pressure between the outlet and inlet sections is then measured.

Dimensions

The outside diameter of the orifice plate is equal to the bolt circle diameter of the connecting flanges minus the diameter of the bolt. This ensures that the plate is centered accurately in the line.

Plate thicknesses depend on line size and differential pressure, and should be sufficient to prevent the plate from bending under operating conditions. Recommended plate thicknesses are shown below.
