Bronkhorst High-Tech has launched a new series of gas flow meters. Bronkhorst, a Netherlands based company established in 1981, offers a range of thermal mass flow meters and controllers.
The new Select range offers more user selection of flow ranges and gas types. Thanks to the combination of the ‘Multi Fluid Range’ feature and ‘high-rangeability’ (up to 187.5:1), equipment manufacturers can reduce the variety of spare instruments which they keep on stock and consequently reduce the cost of ownership. Those who use Mass Flow Metres in pilot plants or laboratories can also rescale their instruments on site.
Similarly, for those who can be categorised as ‘convenience users’, Bronkhorst High-Tech offers free software called FlowTune. By connecting the devices to the RS232 port of a lap-top and running the software, the selection of different flow ranges is made easier. Flow ranges which are covered vary from 0... 1 mlⁿ/min to 0... 1670 lⁿ/min and are available in two configurations.
In particular, the EL-FLOW Select series have housing designed for laboratory and clean processing conditions, meanwhile the IN-FLOW Select version are robust to IP65 standards making them dust and waterproof. The latter are ATEX Category 3 and approved for use in Zone 2 Hazardous areas. In addition to the conventional analogue I/O signals and RS232 connection, users may integrate an interface board with DeviceNet™, Profibus-DP®, Modbus or FLOW-BUS protocol.
Bronkhorst has subsidiary offices in Great Britain, France, Switzerland, northern Germany, USA, Japan, China and Taiwan.
