LOW-ΔP-FLOWF-106xD

Thermal Mass Flow Meters for low pressure drop or corrosive gas applications, industrial style

Bronkhorst® model F-106xD* Mass Flow Meters (MFMs) are suited for precise measurement of flow ranges between 0,2...10 m3n/h and 20...1000 m3n/h (N2-equivalent). The instruments are particularly suited for corrosive gases or applications with very low differential pressure (∆P). Compared to conventional instruments, LOW-∆P-FLOW meters have larger flow channels to minimize the risk of clogging, facilitate cleaning and purging, and cause lower pressure drop (the sensor only requires 0,5 to 5 mbar). This model is of rugged design (IP65) for use in industrial environments or even Zone 2 hazardous areas, with optional ATEX Cat. 3 or FM Class I, Div. 2 approval.

The integrated digital pc-board provides signal and fieldbus conversion as well as PID controller functionality for optional mass flow control by means of a (separately mounted) control valve. 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.

* Series F-106xD consists of the models F-106AD (DIN DN 40 / ANSI 1½”), F-106BD (DIN DN 50 / ANSI 2”), F-106CD (DIN DN 80 / ANSI 3”) and F-106DD (DIN DN 100 / ANSI 4”)
