Orifice plates are the simplest of the DP flow measurement devices. Inexpensive to replace and available in a range of materials; making them an ideal choice for applications where permeant pressure loss is not a significant factor. Devices based on orifice plates remain one of the best selling flow metering technologies. As well as measuring flow, they are used to restrict the flowrate to a certain value or to reduce the pressure at a certain flowrate.
