An ultrasonic flow meter for measuring the flow of a fluid through a pipeline. In an embodiment, the flow meter comprises a spool piece including a throughbore and a transducer port extending to the throughbore. In addition, the flow meter comprises a transducer assembly disposed in the transducer port. The transducer assembly comprises a piezoelectric capsule including a piezoelectric element. Further, the transducer assembly comprises a transformer capsule including a transformer. The transformer capsule is coupled to the piezoelectric capsule. Still further, the transducer assembly comprises a receptacle capsule coupled to the transformer capsule. The receptacle capsule includes a receptacle housing and a receptacle 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.
