CORI-FLOW

CORI-FLOW™ CORIOLIS MASS FLOW METERS / CONTROLLERS

Mass Flow Measurement of low flow rates, independent of fluid properties

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 0…5 kg/h
• up to highest range 0…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.
