The mini CORI-FLOW™ solution

World's smallest, lowest flow Coriolis Meters / Controllers 

With the the development of the mini CORI-FLOW™ series Bronkhorst High-Tech B.V. achieved a technological breakthrough in Coriolis mass flow measurements and control, by realising a compact, cost-effective Coriolis Mass Flow Meter/Controller for accurate measurement and control of (very) low flow rates. The unique design of the miniature Coriolis sensor features unsurpassed performance, even with changing operating conditions in pressure, temperature, density, conductivity and viscosity. Contrary to many other Coriolis flow meters on the market, mini CORI-FLOW™ offers integrated PID control and close-coupled control valves or pumps, thus constituting very compact, cost- and space-saving, precise Coriolis Mass Flow Controllers for low flow liquid and gas regulation.

Lowest range 0.4…20 g/h (5.4…270 mln/min N2)
up to highest range 0.3…30 kg/h (4…400 ln/min N2)

Digital technology

mini CORI-FLOW™ features state-of-the-art digital technology, offering fieldbus interface options and additional functions such as totalisation and alarms. The instruments can be tuned according to customer requirements using the RS232/fieldbus interface and a number of free to use software tools.

Alternative to thermal MFCs

mini CORI-FLOW™ was designed to enable easy exchange of traditional thermal MFCs. mini CORI-FLOW™ flow controllers have the same footprint and also electrically the instruments feature the same options for analog and fieldbus communication. Compared to thermal MFCs, Coriolis based flow controllers are more accurate, faster and offer independence from fluid properties.

  • High accuracy, excellent repeatability
  • Cost-effective design
  • Compact design, with integrated PID controller for fast and stable control
  • Now suitable for (very) low flow ranges
  • Digital technology allows fieldbus communication and offers user configurable control characteristics

Mass Flow Meters
