A measuring device which maximizes the surface area of a blade transducer, which is swingably coupled to a probe member, and utilizes the force of the medium, such as a slurry, flowing in an in-service pipeline to swingably align the blade transducer in a desired measuring position. The swingable coupling of the blade transducer to the probe member provides for the retraction from and insertion into the medium flowing in the in-service pipeline for repairs, replacement, or sanitization or other maintenance or servicing of such blade transducer, without shutting down the pipeline and related processes, without compromising the integrity of or disturbing the connection (sealed, flanged, welded or otherwise) between the measuring device and the transducer port in such pipeline and significantly minimizing the environmental exposure of the medium. Moreover, the retractability feature of the swingable blade transducer enables other components of the measuring device to be replaced, repaired and sanitized or otherwise maintained or serviced, as desired.
