CORI-FLOW™ Coriolis style
Mass Flow Meter / Controller for gas or liquid


CORI-FLOW™ series mass flow meter / mass flow controller are designed to provide high accuracy. CORI-FLOW™ utilizes 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. Control valves can either be close-coupled, to measure and control mass flow ranges from:

lowest range 50…500 g/h
up to highest range 6…600 kg/h

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.


  • 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
  • ATEX approval Cat.3, Zone 2 (option)
  • Analog plus digital communication
  • Integrated PID controller for control valve or pump
  • Integrated totaliser for batch control

"Multibus" Digital Mass Flow Meters/Controllers

A CORI-FLOW™ Coriolis Mass Flow Meter / Mass Flow Controller is offered with analog and digital communication, RS-232 with PROFIBUS DP, Devicenet, Modbus or FLOW-BUS.


The instruments are suited for a variety of applications in:

  • Semiconductor processing
  • Food and beverage industries
  • (Petro-) chemical installations
