The mini CORI-FLOW™ solution
Coriolis Mass Flow Meters / Controllers for (ultra) low flow rates
With the development of the mini
CORI-FLOW™ series Bronkhorst 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 0.1…5 g/h (1.3…66.6 mln/min N2)
up to highest range 3…300 kg/h (39…3900 ln/min N2)
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.
