Abstract

An ultrasonic flow meter for measuring the flow of a fluid through a pipeline. In some embodiments, the ultrasonic flow meter includes a spool piece, a transducer assembly, and a port cover assembly. The spool piece has a throughbore and a transducer port extending between the throughbore and an outer surface of the spool piece. The transducer assembly is disposed within the transducer port and includes a transformer, a piezoelectric element, and an electrical coupling therebetween. The port cover assembly is coupled to the transducer assembly. The port cover assembly receives a cable coupled to the transducer assembly and is spring-loaded to bias the port cover assembly toward the transducer assembly to resist the cable from being electrically uncoupled from the transducer assembly.

Description

[0001] Statement Regarding Federally Sponsored Research or Development [0002] Not applicable technical field [0003] The disclosed embodiments relate to ultrasonic flow meters, and more particularly to port cover assemblies for transducer assemblies coupled in ultrasonic flow meters. Background technique [0004] After the hydrocarbons have been removed from the surface, the fluid flow, whether in liquid or gaseous phase, is transported from one place to another via pipelines. It is desirable to have precise knowledge of the amount of fluid flowing in a fluid stream, and special precision is required when fluid is changed hands or during "closed transfers". However, measurement accuracy is desired even where hermetic transfer does not occur, and in these cases ultrasonic flow meters can be used. [0005] Ultrasonic flow meters include two or more transducer assemblies, each secured inside the body of the flow meter or a port in a bobbin piece. To retain the delivered f...
