Low-frequency ultrasonic flow measurement in hot flue gasThe BBFM-Q25K-B is a 25 kHz ultrasonic flow transducer designed for continuous service in high-temperature flue-gas environments. It is suitable for flue-gas flow monitoring, boiler exhaust measurement, industrial emission ducts and transit-time measurement in hot gases where elevated temperatures and corrosive atmospheres are present.
Applications- Flue-gas flow measurement
- Boiler exhaust monitoring
- Industrial emission ducts
- High-temperature gas transit-time measurement
Selection and integrationChoose the BBFM-Q25K-B considering gas composition and temperature, required acoustic path length, duct geometry and available installation space. Confirm operating pressure and ingress protection needs, and verify compatibility with your drive and receive electronics.
