Title: Kiyoshi Koyano: Innovator in Ultrasonic Flow Measurement
Introduction
Kiyoshi Koyano is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of fluid measurement technology, particularly through his innovative ultrasonic flow meters. With a total of 2 patents to his name, Koyano's work exemplifies the intersection of engineering and practical application.
Latest Patents
Koyano's latest patents focus on advanced ultrasonic flow meters designed to accurately determine the flow rate of fluids in tubing. The first patent describes an ultrasonic flow meter that features a measuring tube with a constant diameter throughout its length. This device utilizes two ring-shaped oscillators positioned longitudinally along the tube. One oscillator generates an ultrasonic wave, while the other detects it. The time taken for the wave to travel between the oscillators is measured, allowing for the calculation of fluid velocity.
The second patent expands on this concept by incorporating a third ring-shaped oscillator. In this design, the central oscillator generates the ultrasonic wave, which is then detected by both forward and rearward oscillators. The data collected by these oscillators is processed through a comparator to determine the flow rate of the fluid flowing through the measuring tube.
