One of the earlier flow meters in use was the orfice plate flowmeter which uses a plate with a hole through it, placed in the fluid flow. This orfice plate constricts the flow, resulting in a pressure differential across the constriction. By knowing the area of the constriction and the pressure differential the flow rate can be determined. There are threecommon types of orifices in use: concentric, eccentric, and segmental
