The Netherlands-based Bronkhorst High-Tech BV has expanded their database
of gas and liquid properties from 1000 fluids to over 1800 fluids. Called
FLUIDAT, this comprehensive database is used by the company for configuration
and extremely accurate calibration of their extensive portfolio of flow meters
and controllers, as well as for calculating pressure differences and valve
seats among others.
This accurate database is also available as a free, online calculation
tool for Bronkhorst customers who want to determine conversion factors when
they use their flow meter for a gas (or gas mixture) other than that for which
the instrument is calibrated. This online calculation tool, Fluidat on the Net, is also very valuable
for physicists who need to calculate fluid properties or read the
vapour pressure curve.
EL-FLOW Prestige, Bronkhorst’s high-performance range of gas mass flow
meters and controllers, comes equipped with the data of 100 unique gases from
the FLUIDAT database, offering the user excellent flexibility in varying gas
types with optimum accuracy. With the embedded gas data, the EL-FLOW Prestige
calculates in real-time, the gas conversion based on the actual gas properties.
The free and easy-to-use software tool FlowTune enables the user to change the
instrument’s configuration swiftly via the RS232 port of their computer.
