Direct mass flow meters and controllers

The new In-FlowcTA mass flow meters by Bronkhorst are modular instruments of rugged design according IP 65. They can be combined with integrated or close-coupled control valves to form compact digital mass flow controllers, whereby flow ranges are measured and controlled within the range of 10…200 ml/min up to 50…5000 l/min. The ATEX approval for use of these instruments in Category 3, Zone 2 hazardous areas is pending.

Mass Flow Meters of the In-FlowcTA series work at the basis of direct through-flow measurement (no by-pass), following the constant temperature anemometer principle. The instruments contain no moving parts and have no obstructions to the flow path, which makes them ideal for low pressure drop applications and virtually insensitive to moisture or particulates.
The instruments have analog 1/0-signals and also an RS232 connection as a standard feature. In addition to this there is the possibility of integrating an interface board with DeviceNeF“, Profibus-DP®, Modbus or FLOW-BUS protocol. The basic PC-board features integrated PID Control and various alarm and diagnostic functions. With these multiple functions and its rangeability up to 1:100, the new IN-FLOWcTA series truly offers an excellent price-performance ratio. Applications can be found in process control systems as for example in food, chemical and petrochemical plants.
