Title: Hiroo Yamasaki: Innovator in Flow Measurement Technology
Introduction
Hiroo Yamasaki is a notable inventor based in Musashino, Japan. He has made significant contributions to the field of flow measurement technology. His innovative approach has led to the development of a unique flow velocity measuring device.
Latest Patents
Yamasaki holds a patent for a flow metering apparatus that utilizes a vortex generating element. This element is designed with a generally elongate cylindrical shape, placed in a stream of flowing fluid within a pipe. It produces Karman's vortices at a rate that is proportional to the fluid's velocity. The device incorporates ultrasonic means for detecting the rate of vortex production, providing a linearly related measure of fluid velocity. To enhance detection sensitivity, especially at low velocities, the element features a passageway that creates an alternating fluid flow corresponding to the shedding of vortices. An ultrasonic generator and receiver are strategically positioned to optimize signal propagation through the passageway. Additional improvements include the use of elastic O-rings for mounting the ultrasonic components, which minimizes sound transmission to and from the pipe. Flow deflecting projections on the inner wall of the pipe further enhance vortex generation conditions and detection accuracy.
