McMenon - Orifice Plates
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.
The technology is well-understood and thoroughly proven and is available from McMenon in a wide range of designs to suit most applications. From simple plates to metering runs, McMenon have an orifice plate, union or orifice carrier for all orifice applications – simple flow measurement, flow restriction or pressure reduction.
