FLOW CHANNEL DEVICE FOR OPTICAL METHANOL SENSOR

摘要

PPROBLEM TO BE SOLVED: To provide a flow channel device capable of improving the reliability of an optical methanol sensor. PSOLUTION: A flow channel device for an optical methanol sensor 10 includes: an inner housing 210 by which an optical methanol sensor body 60 is surrounded; an outer housing 220 by which the inner housing 210 is surrounded; a flow channel 216 formed in the inner housing 210 so as to correspond to a total reflection surface (first surface 11) of the optical methanol sensor body 60; an inlet 222, formed so as to extend through the inner housing 210 and the outer housing 220, via which liquid fuel is supplied to the flow channel 216; and outlets 214 and 224, formed so as to extend through the inner housing 210 and the outer housing 220, via which the liquid fuel having passed through the flow channel 216 is discharged from the inner housing 210 and the outer housing 220.
