OPTIMASS 7400

Overview

The OPTIMASS 7400 is a high-end Coriolis mass flowmeter for demanding process and custody transfer (CT) applications. It is the ideal solution when it comes to high accuracy measurement of gases and shear-sensitive or viscous liquids, slurries, very aggressive media or media with a low flow velocity. The meter features Entrained Gas Management (EGMTM) for liquid applications and thus maintains operation even with entrained gas of up to 100%.

Product features and options depend on device configuration: Contact us to make sure that your preferred functionality can be combined in one device.

  • Single straight tube design
  • Entrained Gas Management (EGMTM): maintains operation with air or gas entrainments in the medium
  • Device commissioning, verification, diagnostics and monitoring via a secure wireless Bluetooth® connection (<20 m / 65.6 ft)
  • Fast and completely digital signal processing
  • High accuracy mass, density and volume flow measurement (±0.1% of MV)
  • Highest OIML accuracy class of 0.3 for custody transfer (CT)
  • Extensive sensor and process diagnostics (incl. NE 107)
  • Integrated temperature measurement
  • Available in four sensor materials: titanium, stainless steel, Hastelloy® or tantalum
  • With sensor size DN80 / 3" in titanium or Hastelloy® it is the largest single straight tube meter on the market
  • Optional PED approved secondary pressure containment up to 100 barg / 1450 psig
  • Many options (heat tracing, purge port etc.)
  • No crosstalk: resistant to installation and process effects
  • Various approvals and certifications (hygienic, custody transfer, marine, hazardous areas etc.)
  • On-site verification of flowmeter with OPTICHECK service tool
