Selection and integration
Select the transducer based on gas composition and temperature, required acoustic path length, duct geometry and available installation space. Verify compatibility with operating pressure and ingress protection needs, and ensure drive/receive electronics match the transducer's impedance and voltage requirements. Consider mounting arrangement and coupling medium for reliable ultrasonic transmission.
