ULTRASONIC FLOW METER AND TRANSDUCER ASSEMBLY WITH ISOLATED TRANSFORMER CAPSULE |
摘要 |
In an embodiment, an ultrasonic flow meter comprises a spool piece including a throughbore and a transducer port extending from the outer surface of the spool piece to the throughbore. In addition, the ultrasonic flow meter comprises a transducer assembly disposed in the transducer port. The transducer assembly has a central axis and comprises a transducer holder having a first end proximal the throughbore of the spool piece, and a second end distal the throughbore of the spool piece. Further, the transducer assembly comprises a piezoelectric capsule including a piezoelectric element. The piezoelectric capsule is coupled to the transducer holder and extends generally axially from the first end of the transducer holder. Still further, the transducer assembly comprises a transformer capsule including a transformer. The transformer capsule is coupled to the transducer holder and is axially spaced apart from the piezoelectric capsule. |
