Abstract
An ultrasonic flow meter comprises a flow channel for a fluid to be measured to flow through, an ultrasonic transducer having an acoustic matching body and a piezoelectric element fixed to a metal plate, an insulating damping member which covers the metal plate except for the acoustic matching body, a mounting portion provided in the flow channel, and a fixing member that fixes the ultrasonic transducer to the mounting portion, The fixing member has a pressing portion and an extended portion, and the ultrasonic transducer is fixed to the mounting portion by engaging a hole disposed in the extended portion with a hook disposed on the mounting portion. This structure reduces through-the-case conduction, and achieves the ultrasonic flow meter of high accuracy.
