CORI-FLOW Series, Coriolis Mass Flow Meters and Controllers

CORI-FLOW Series, Coriolis Mass Flow Meters and Controllers

CORI-FLOW Series mass flow meters and mass flow controllers are designed to provide high accuracy by utilizing a patented, advanced Coriolis type direct mass flow sensor to achieve unsurpassed performance – even with changing operation conditions in pressure, temperature, density, conductivity, and viscosity. The control valve design distinguishes itself from competitive designs in its truly modular construction and it can be field replaced or changed by the user without any adjustment. The standard valve is normally closed and is available up to Kv-values of 1.5. Normally opened valves can also be supplied. Control valves can either be close-coupled, to measure and control mass flow ranges from:

  • lowest range 0-5 kg/h
  • up to highest range 0-600 kg/h


  • direct mass flow measurement
  • fast response time
  • high accuracy (0.2% Rd + ZS for liquids, 0.5% Rd + ZS for gases)
  • highly stable
  • compact Coriolis controller
  • all wetted parts stainless steel; option: Hastelloy-C22
  • IP65 housing
  • optional: ATEX approval Cat.3, Zone 2
  • optional: KCs certificate (Protection Ex nA IIC T4)
  • analog plus digital communication
  • integrated PID controller for control valve or pump
  • integrated totalizer for batch control
