Mass Flow Controller Suited For Harsh Environments

Bronkhorst High-Tech has expanded its IN-FLOWCTA series of mass flow meters/controllers with the introduction of the T23. It is a compact mass flow controller with a newly developed integrated, direct operating valve that can cope with high gas flow rates.

The maximum flow control range of the instrument is 12 to 600 Ln/min. Both analog I/O signals and RS232 connection are available as standard. In addition, there is the possibility of integrating an interface board with DeviceNet, PROFIBUS DP, Modbus or FLOW-BUS protocol. Applications can be found in process control systems, for example in food, chemical and petrochemical plants. All proprietary flow meters/controllers work on the basis of direct through-flow measurement (no bypass), following the constant temperature anemometry 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 less sensitive to moisture or particulates than thermal mass flow devices with bypass sensor. The electronics housing is rugged, dust- and water-proof. The flow meters and controllers are available with optional ATEX approval for use in Category 3, Zone 2 hazardous areas.
