MASS-STREAMD-6471/DR3 MFC

IP65 Mass Flow Controllers for high gas flow at Low-ΔP

Bronkhorst® model D-6471/DR3 Mass Flow Controllers (MFCs) are suited for precise measurement of flow ranges between 6…300 ln/min and 60…3000 ln/min at operating pressures between 30 mbar and 5 bar(g). The MFC consists of a proven inline thermal (CTA) mass flow sensor, an advanced, innovative 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 of TCP/IP, EtherNet/IP, POWERLINK of FLOW-BUS protocols.

Note: Please respect our instructions regarding inlet pressure and straight pipe run at the inlet and the outlet of the instrument (see datasheet).
