OPTIMASS 6400

Overview

The OPTIMASS 6400 is the standard high performance Coriolis mass flowmeter for the process industry. The twin bent tube meter offers superior performance and high accuracy in virtually any application: From process control in (petro)chemical applications to concentration measurements in the food and beverage industry to custody transfer filling and transport measurements in the oil and gas industry. Its high-end options also make the OPTIMASS 6400 the optimum device for cryogenic media like Liquefied Natural Gas (LNG) with temperatures down to -200°C / -328°F as well as applications involving high operating temperatures (up to 400°C / 752°F) or pressures (up to 200 barg / 2900 psig).

  • Twin bent tube design
  • Entrained Gas Management (EGMTM): maintains operation with air or gas entrainments in the medium
  • The only Coriolis mass flowmeter on the market allowing secure wireless access via Bluetooth® or remotely via HART® in safety-related applications
  • Device commissioning, verification, diagnostics and monitoring via a secure wireless Bluetooth® connection (<20 m / 65.6 ft)
  • SIL 2/3 certified up to DN200 / 8″
  • Partial proof test possible with PTC (Proof Test Coverage) of up to 82%
  • Fast and completely digital signal processing
  • Integrated temperature measurement
  • Optimised flow splitter for minimum pressure loss
  • High accuracy mass, density and volume flow measurement (optional ±0.05% of MV)
  • Highest OIML accuracy class of 0.3 for custody transfer (CT)
  • Extensive sensor and process diagnostics (incl. NE 107)
  • Available in three different sensor materials (incl. Duplex and alloy 22)
  • Many options (heat tracing, purge port etc.)
  • Self draining when mounted vertically
  • No crosstalk: resistant to installation and process effects
  • On-site verification of flowmeter with OPTICHECK service tool possible
