Title: Shinya Otsuki: Inventor of a Corrosion-Resistant Coriolis Mass Flowmeter

Introduction

Shinya Otsuki is an inventor associated with Chiba, Japan. His work includes a patent for a Coriolis mass flowmeter designed to measure corrosive fluids while avoiding the risk of metal-ion elution. Otsuki has been associated with Alphitechnology Co., Ltd. and Kofloc Corp.

Latest Patents

Otsuki’s listed patent is “Coriolis mass flowmeter with no risk of metal ion elution.” The invention describes a straight tube that carries the fluid being measured, an exciter that makes the tube vibrate, and two detectors that sense its vibration. Supports hold the tube’s ends, while frames connected to the supports carry the exciter and detectors. The instrument determines the fluid’s mass flow rate from the phase shift between the vibration waveforms detected at the two points.

The tube, supports, and frames are made from a highly elastic plastic material. This construction is intended to enable measurement of corrosive fluids without the risk of metal ions eluting from those components. Otsuki is credited with 1 patent.
