The mini CORI-FLOW™ solution
General
With 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 0.1…5 g/h (1.3…66.6 mln/min N2)
up to highest range 3…300 kg/h (39…3900 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.
Features
- Direct mass flow measurement, for liquids and gases
- 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
