Title:
流体測定装置
Document Type and Number:
Japanese Patent JP7010248
Kind Code:
B2
Abstract:
First to N-th (N is an integer of three or more) sensor elements each including a light source unit and a light reception unit are arranged around a tube that allows a fluid containing scatterers to flow at equiangular intervals, and coherent light which is emitted from the light source unit of any one sensor element of the first to N-th sensor elements and is transmitted through the fluid flowing through the tube is received by the light reception unit of another predetermined sensor element of the first to N-th sensor elements. At this time, when a distance between the light source unit and the light reception unit of any one sensor element is d and an outer radius of the tube is r, a distance between any one sensor element and another predetermined sensor element is set to πd/2 or more and √3r or less.
