Bronkhorst High-Tech In-Flowcta mass flow meters

Bronkhorst High-Tech In-Flowcta mass flow meters are modular, ruggedly designed, IP65 rated, dust free and waterproof.

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 on the basis of direct through-flow measurement (no bypass), following the constant temperature anemometer principle. The instruments contain no moving parts and have no obstructions to the flow path, which makes them suitable for low pressure drop applications and virtually insensitive to moisture or particulates.

The instruments have analog I/O signals and also an RS232 connection as a standard feature. In addition, there is the possibility of integrating an interface board with DeviceNet, Profibus-DP, Modbus or Flow-Bus protocol. The basic PC board features integrated PID control and various alarm and diagnostic functions.

The flow meters can be applied in process control systems, for example in food, chemical and petrochemical plants.
