AI Technical Summary

Technical Problem

Conventional Coriolis flow sensors are expensive and not suitable for single-use or disposable applications, and their sterilization using chemicals can lead to cross-contamination, while increasing mass to reduce interference introduces weight and cost issues.

Method used

A Coriolis flow sensor design that includes a lightweight, disposable or single-use flow sensor enclosed in a gamma-transparent plastic housing, which can be sterilized by gamma irradiation and attached to a heavy cradle that increases its effective mass to reduce zero drift and interference, while allowing for easy replacement and sterilization.

Benefits of technology

The solution provides accurate flow measurements with reduced zero drift and cost, suitable for single-use applications, and effective sterilization without cross-contamination, enhancing the sensor's suitability for bio-pharmaceutical and pharmaceutical industries.

Abstract

A Coriolis flow sensor includes a metal flow tube and an enclosure. The enclosure encloses the flow tube and is constructed at least partially from a gamma transparent material. The metal flow tube may be constructed from stainless steel. The gamma transparent material and the flow tube are thin enough to permit sterilization of an interior of the flow tube by gamma irradiation of the flow tube through the gamma transparent material. The enclosure is also shaped to facilitate locking and unlocking the Coriolis flow sensor in place on a mounting structure.
