  • Air/Gas Flow Meter Now Withstands 850°F (454°C) For Use In High Temperature Processes
    The sensors are two matched precision platinum resistance temperature detectors (RTDs) in which one RTD is heated relative to the reference RTD, and the temperature difference between the two RTD's is proportional to the process gas mass flow rate. Transmitter housing options include a weather-proof, NEMA 4/IP66 rated carbon steel enclosure, a NEMA 4X (IP66) rated aluminum enclosure, or a Division 1 (Zone 1) rated explosion-proof aluminum enclosure.
