Ultrasonic transit-time flow transducer BBFM-Q1M-C

massgasfor process monitoring

Overview
The BBFM-Q1M-C is an ultrasonic transit-time transducer designed for flue-gas flow measurement in industrial ducts, boiler exhausts and high-temperature gas lines. It operates from -20 to +100°C, withstands pressures up to 10 kgf (≈1 MPa) and is rated IP68 for protection against dust and immersion.
