  • Abstract
    In this paper, a micromachined Coriolis mass flow sensor is described. Key to portability, this resonant silicon sensor is vacuum packaged at the chip-level. A new MEMS gettering method was developed to accomplish high-vacuum packaging. Fluids flow through machined silicon microtubes. The tubes are driven electrostatically and monitored capacitively. Test data and applications are presented.
