A Coriolis flow meter for measuring one or more properties of a fluid is described herein which involves a modular configuration, and includes a fluid flow sub-system and a mechanical oscillator sub-system, both functionally separate, and are coupled in a closed loop arrangement, such that the flow conduit is not directly vibrated, and instead receives induced oscillations from the mechanical oscillator sub-system. The Coriolis flow meter is useful for high purity applications, as well as for the bioprocessing applications. Bioprocessing systems incorporating the Coriolis flow meter are also described herein. Method for measuring one or more properties of a fluid using the disclosed Coriolis flow meter are also described herein.
