1. A process comprising:
obtaining a Coriolis mass flow sensor comprising at least one metal flow tube enclosed within an enclosure that is shaped to facilitate locking and unlocking the Coriolis flow sensor in place on a mounting structure, the enclosure constructed at least partially from a gamma transparent material, wherein the gamma transparent material and the metal flow tube are thin enough to permit sterilization of an interior of the metal flow tube by gamma irradiation of the metal flow tube through the gamma transparent material;
sterilizing the Coriolis mass flow sensor by using Gamma irradiation; and
storing calibration data for the Coriolis flow sensor in a gamma stable memory.
