Emerson's Coriolis flowmenters get CSA dual-seal certification

Boulder, Colo., November 7, 2007 – Emerson Process Management announces that all Micro Motion ELITE Coriolis flowmeters have achieved CSA dual-seal certification, ensuring dual seal safety when processing flammable or combustible process fluids, and eliminating the need for secondary seals. The CSA certification for the U.S. and Canadian markets is to ANSI/ISA 12.27.01 standard, which presents requirements for Process Sealing between Electrical Systems and Flammable or Combustible Process Fluids.

The certification shows that the entire range of Micro Motion ELITE meters are compliant and are eligible to be marked as “Dual Seal.” The Dual Seal marking eliminates the need to install secondary seals to prevent the possibility of process fluids migrating under pressure through the electrical conduit, cable and wire systems in the event of a failure of the primary seal. Recent changes to the Canadian Electrical Code and National Electric Code make it mandatory for users to install secondary seals if the device does not include either a “Single Seal” or “Dual Seal” marking on the nameplate.

By having the “Dual Seal” certification, Micro Motion ELITE meters provide significant customer benefits due to the elimination of the need to install secondary seals, thereby saving installation time and cost. Ideally suited for refineries, oil production and petrochemical operations, Micro Motion ELITE meters also deliver substantial inherent benefits as they have no moving parts resulting in no maintenance or repair, can be installed without flow conditions or straight pipe runs, are accurate over a wide flow range, and deliver direct mass and volume measurement.
