Flow Measurement
Orifice Plates
McMenon have an orifice plate, union or carrier for all orifice applications.
Overview
The simplest of the DP flow measurement devices.
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.
