Ultrasonic flow transducer BBFM-Q34K

ultrasonic transit-timevolumegas

Overview
The BBFM-Q34K is a 34 kHz ultrasonic flow transducer designed for flue-gas flow measurement, boiler exhaust monitoring and industrial emission ducts. It is suitable for transit-time measurement in high-temperature gas. Operating range: -20 to +150°C. Rated for pressures up to 3 kgf (0.3 MPa) and carrying an IP68 protection rating. The housing is stainless steel to resist corrosion in exhaust environments.
