EL-FLOW® Digital Mass Flow Meters and Controllers for Gases "The MFC that speaks your language"

    The Mass Flow Meters of the EL-FLOW^® Series are compact, modular instruments. They can be combined with control valves, either integrated or separate, in order to measure and control gas flows in ranges starting from 0,06…3 mln/min up to 25…1250 ln/min air-equivalent. Bronkhorst High-Tech B.V. 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® or FLOW-BUS protocol. The last mentioned is a fieldbus based RS485, specifically  designed by Bronkhorst High-Tech B.V. for their mass flow metering and control solutions, thanks to which the company already has over ten years of experience with digital communication.
