Title: Nozomi Kojima: Inventor of a Corrosion-Resistant Coriolis Mass Flowmeter.
Introduction
Nozomi Kojima is an inventor associated with Kyoto, Japan. Her work includes a Coriolis mass flowmeter designed to measure corrosive fluids while avoiding the elution of metal ions.
Latest Patents
Kojima is credited with 1 patent: “Coriolis Mass Flowmeter with No Risk of Metal Ion Elution.” The invention uses a straight tube through which the measured fluid flows, a vibration exciter, and two vibration detectors. It determines the fluid’s mass flow rate from the phase shift between the vibration waveforms detected at two points.
The tube, its supports, and the frames carrying the exciter and detectors are made of a highly elastic plastic material. This construction is intended to reduce the risk of metal ions entering corrosive fluids.
Career Highlights
Kojima’s listed company affiliations include Alphitechnology Co., Ltd. and Kofloc Corp. Her patent reflects an engineering approach focused on flow measurement and material selection for corrosive-fluid applications.
Collaborations
Her listed coworkers include Shinya Otsuki and Keiji Kido.
Conclusion
Nozomi Kojima’s patented flowmeter combines vibration-based mass measurement with plastic components designed to help prevent metal-ion elution when measuring corrosive fluids.
