New mass flow controller features flexibility and cost reduction

February 2007 Flow Measurement & Control

Bronkhorst High-Tech (The Netherlands) introduced the 'Mass Flow Select' series of digital mass flowmeters and controllers for gases at Frankfurt-am-Main's Achema in May. These new instruments offer greater flexibility for user selection of both flow ranges and gas types. As a result of this new feature, original equipment manufacturers are able to reduce the variety of spare instruments they keep in stock and thus reduce the cost of ownership. Users of MFCs in pilot plants or laboratories can rescale their instruments on site, saving time and money for dismounting and recalibration.

For the convenience of the user, Bronkhorst High-Tech has developed a software tool called FlowTune. By connecting the instrument to the RS232 port of a lap-top and running this freeware configuration tool, the selection of different flow ranges is simple.

The new instruments, covering flow ranges from 0 to 1 mln/min up to 0 to 1800 In/min, are available in two configurations. The EL-FLOW Select series have a housing designed for laboratory and clean processing conditions, while the IN-FLOW Select series are of rugged design according to IP65 (dust-and waterproof). The latter are also ATEX Category 3, approved for use in Zone 2 hazardous areas. In addition to the standard analog I/O-signals and the RS232 connection, there is the possibility of integrating an interface board with DeviceNet, Profibus-DP, Modbus or Flow-Bus protocol.

Mecosa is the sole agent for Bronkhorst High-Tech in South Africa.
