The Dwyer Instruments GFM-2102 is a high-performance gas mass flow meter designed for precise measurement of gas flow in industrial processes. With a flow range of 0-200 SCFM (equivalent to nitrogen at 70°F and 760 mm Hg), this thermal dispersion meter provides accurate and repeatable readings, virtually unaffected by temperature and pressure variations. The GFM-2102 features a 3-1/2 digit, 90° tiltable LCD display for easy reading, and offers both 4-20 mA analog output and Modbus RTU digital communication for seamless integration into control systems.
