Brooks Instrument’s GF40 and GF80 thermal mass flow controllers (MFCs) offer a configurable platform based on modular architecture, enabling drop-in replacement for quick upgrades. The MFCs allow end-users to standardize on one MFC over a range of applications, providing reduced inventory and operational costs. The controllers operate with Brooks’ patented MultiFlo technology for process-gas accuracy. MultiFlo allows users to reconfigure the MFC for a new gas and range without the time and cost of removing the device from the gas line. The MFCs are also equipped with an independent diagnostic/service port to troubleshoot or change flow conditions without removing the MFC from service. The controllers feature sub-one second settling times and corrosion-resistant Hastalloy sensor tube for long-term stability. The valve technology provides minimum leak-by, maximum turndown and fast-response, which reduces overall gas panel cost and increases throughput. The measurement accuracy of every device is verified using traceable primary calibration standards. –
