Compact mass flow controller follows anemometry principle

With the introduction of the T23 model, Bronkhorst High-Tech have expanded their IN-FLOWCTA series of Mass Flow Meters /Controller for industrial applications.

The “T23” is a compact Mass Flow Controller with an integrated, direct operating valve that can cope with high gas flow rates. The maximum flow control range of the instrument is 12-600ln/min. Both analog I/O-signals and RS232 connection are available as a standard feature. In addition to this there is the possibility of integrating an interface board with DeviceNet, PROFIBUS DP, Modbus or FLOW-BUS protocol.

The instrument works by directing through-flow measurement (no by-pass), which follows the constant temperature anemometry principle. Containing no moving parts, the instruments 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 by-pass sensor.

Available with optional ATEX approval for use in Category 3, Zone 2 hazardous areas, the electronics housing is of a rugged design according IP65 (dust- and waterproof). Applications can be found in process control systems as for example in food, chemical and petrochemical plants.
