Compact IP65 Mass Flow Controllers for medium flow rates of gases

Bronkhorst® models D-6361/002BI and D-6461/002BI Mass Flow Controllers (MFCs) are suited for precise measurement of flow ranges between 0,4…20 ln/min and 4…200 ln/min at operating pressures between vacuum and 10 bar (Aluminium) or 20 bar (Stainless Steel). The MFC consists of a proven inline thermal (CTA) mass flow sensor, a precise control valve and a microprocessor based pc-board with signal and fieldbus conversion. As a function of a setpoint value, the flow controller swiftly adjusts the desired flow rate. The instument is IP65 complient and can optionally be equipped with a modern, multi-functional and multi-colour display, with operator buttons on the instrument.

The digital MASS-STREAM™ series is characterized by a high degree of signal integrity and, as an option, up to 8 calibration curves of different gases and process conditions can be memorized in the instrument. In addition to the standard RS232 output the instruments also offer analog I/O. As an option, an on-board interface can be mounted to provide CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus RTU, ASCII or TCP/IP, EtherNet/IP, POWERLINK or FLOW-BUS protocols.
