IN-FLOW Industrial style (IP65, ATEX Zone-2) - Bronkhorst - #1

Text version of the page

> Introduction Bronkhorst High-Tech B.V., the European market leader in thermal Mass Flow Meters/Controllers and Electronic Pressure Controllers, has 25 years experience in designing and manufacturing precise and reliable measurement and control devices. With a wide range of instruments, Bronkhorst High-Tech is offering innovative solutions for many different applications in many different markets. The instruments are made to customers’ specification, in various styles, suitable for use in laboratory, industrial environment, hazardous areas, semiconductor or analytical installations. > IN-FLOW series for Industrial Environments The Mass Flow Meters of the IN-FLOW series are of rugged design (IP65) for use in pilot and production plants in industrial environments. Mass Flow Meters can be supplied in ranges starting from 0,02…1 mln/min up to 11000 m3 n/h air-equivalent, with pressure rating between vacuum and 700 bar. In combination with control valves, either integrated or separate, Mass Flow Controllers can be offered up to 10…500 m3 n/h air-equivalent. The instruments of the IN-FLOW series are now available with ATEX approval for use in Zone 2 hazardous areas. > Multi-Bus Technology Bronkhorst High-Tech developed their latest digital instruments according to the “multi-bus” principle. The basic pc-board on the instrument contains all of the general functions needed for measurement and control. It has analog I/O-signals and also an RS232 connection as a standard feature. In addition to this there is the possibility of integrating an interface board with DeviceNet™, Profibus-DP®, Modbus-RTU or FLOW-BUS protocol. The latter is a fieldbus based RS485, specifically designed by Bronkhorst High-Tech for their mass flow metering and control solutions, and through which the company already has over ten years of experience with digital communication. > Mass Flow Controllers for every application The control valve can be furnished as integral part of an IN-FLOW MFC, or as separate component. It is a proportional, electromagnetic control valve with extremely fast and smooth control characteristics. With reference to the specific field of application there are different series of control valves. There is a standard direct acting valve for common applications, a pilot operated valve for high flow rates, the so-called Vary-P valve with pressure rating 400 or 700 bar, that can cope with up to 400 bar ÄP and a bellows valve for applications with very low differential pressure. > General IN-FLOW features u weatherproof IP65 housing u ATEX approval Cat.3, Zone 2 u fast response, excellent repeatability u flow ranges from 0,02…1 mln/min up to 220…11000 m3 n/h u pressure ratings up to 700 bar > Digital features u DeviceNetTM, PROFIBUS-DP®, Modbus-RTU or FLOW-BUS slave u RS232 interface u other fieldbus options on request u alarm and counter functions > Fields of application u Process gas measurement or control in food, pharmaceutical and (petro-) chemical industries, in fermentation installations and in fuel cell technology u Sample gas measurement u Burner control u Gas consumption measurement for internal accounting u Making of defined gas mixtures IN-FLOW Industrial Style Digital Mass Flow Meters and Controllers for Gases
