APPARATUS FOR MEASURING FLOW RATE OF COMPONENT

Title:

APPARATUS FOR MEASURING FLOW RATE OF COMPONENT

Document Type and Number:

Japanese Patent JPS60117149

Kind Code:

A

Abstract:

PURPOSE: To reduce the load imparted to a person to be examined by reducing a dead space amount, by making it possible to perform the measurements, of a flow rate and a concn. by one tubular body.

CONSTITUTION: A flow rate/concn. simultaneous measuring tube is constituted by attaching a flow rate measuring ultrasonic transducer and a concn. measuring optical sensor to one tubular body 2 through which a fluid to be measured, for example, breathing air. That is, a pair of ultrasonic vibrators 4a, 4b are attached and a pair of light transmittable windows 5a, 5b for measuring a concn. are attached between the vibrators 4a, 4b so as to be opposed to each other in an air-tight state. Further, a flow rate measuring circuit 6 is connected to a pair of the ultrasonic vibrators 4a, 4b and a component concn. measuring circuit 14 is connected through the light transmittable windows 5a, 5b.
