Dual Chamber Orifice Meters
Dual Chamber Orifice Meters are available in a range of standard line sizes and configurations with optional materials available upon request.
Dual Chamber Orifice Meters are used for flow measurement applications. This device is utilised to aid orifice plate inspections without the need to break the flange pipeline integrity. No line shutdown and depressurisation is required as the chamber houses a block and bleed isolation. The plate is housed in a carrier ring with seals to mitigate any process bypass of the plate causing mis-measurement.
Economical and easy-to-use, this low maintenance flow measurement device simplifies the plate inspection and removal process without the need for costly line intervention.
