An ultrasonic flow meter (100) for measuring the flow of a fluid through a pipeline. In an embodiment, the flow meter comprises a spool piece (105) including a throughbore (130) and a transducer port (165) extending to the throughbore. In addition, the flow meter comprises a transducer assembly (200) disposed in the transducer port. The transducer assembly comprises a piezoelectric capsule (210) including a piezoelectric element (212). Further, the transducer assembly comprises a transformer capsule (250) including a transformer. The transformer capsule is coupled to the piezoelectric capsule. Still further, the transducer assembly comprises a receptacle capsule (300) coupled to the transformer capsule. The receptacle capsule includes a receptacle housing (310) and a receptacle (340) coaxially disposed within the receptacle housing. The receptacle is electrically coupled to the transformer. Moreover, the receptacle is rotatable relative to the receptacle housing between a first position and a second position. |
