Bronkhorst High-Tech Select series digital mass flowmeters

Bronkhorst High-Tech has released the Select series of digital mass flowmeters and controllers for gases. The meters offer greater flexibility for user selection of both flow ranges and gas types. As a result of the ‘multi fluid multi range’ feature, in combination with a high rangeability (up to 187.5:1), users will be able to reduce the variety of spare instruments they keep on 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, the company has developed a free software tool called FlowTune. By hooking up the instrument to the RS232 port of a laptop and running this freeware configuration tool, the selection of different flow ranges is simple.

The instruments, covering flow ranges from 0-1 mL/min up to 0-1670 L/min, are available in two configurations. The El-Flow Select series has a housing designed for laboratory and clean processing conditions, while the In-Flow Select series is 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.
