Fabrication and characterization of Coriolis mass flowmeter made from Ti-based glassy tubes

Bulk metallic glasses (BMGs) have potential applications for both structural and functional components owing to their good mechanical properties. With the aim of demonstrating great engineering value of BMGs, we have developed a direct melt-forming technique based on suction casting for the production of glassy alloy tubes. We have examined the fabrication, structure, geometry, properties and sensor performance of the tubes. We have observed that the Coriolis mass flowmeters using the Ti-based glassy alloy sensor tube exhibit excellent measurement sensitivity compared to the conventional flowmeter manufactured using stainless steel (SUS316) tube.
