The In-Flow series of Bronkhorst High-Tech mass flow meters are compact, modular instruments of rugged design according IP 65. They can be combined with control valves, either integrated or close-coupled, whereby gas flows are measured and controlled within the overall range of 0.2 ml/min up to 11,000 m³/h air equivalent. The instruments are Atex approved for use in Category 3, Zone 2 hazardous areas. The digital mass flow meters/controllers are developed by following the multi-bus principle. The basic pc-board on the instrument contains all of the general functions needed for measurement and control, including alarm, totalisation and diagnostic functions. It has analog I/O-signals and also an RS232 connection as a standard feature.
