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

Bronkhorst® model F-102E Mass Flow Meters (MFMs) are suited for precise measurement of flow ranges between 0,17…8,5 ln/min and 1…50 ln/min (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).

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.
