範囲第１項記載の配管内気液識別装置。[Claims for Utility Model Registration] (1) A connecting part having a connecting means for connecting to piping through which a fluid flows and a fluid passage through which the fluid flows, and a mounting part having a mounting space opening into the fluid passage. a transparent body installed in the mounting space of the mounting part of the body, exposed in the fluid passage of the connecting part, and having a pair of inclined surfaces located in mutually intersecting planes on the exposed part; an optical element, a light emitting element that sends incident light to one inclined surface of the optical element, and a light emitting element that receives reflected light when the incident light from the light emitting element is totally reflected on each inclined surface of the optical element. A gas-liquid identification device in piping, comprising a light-receiving element that recognizes whether the fluid flowing in the fluid passage of the connecting portion is liquid or gas. (2) The gas-liquid identification device in piping according to claim 1, wherein the light-emitting element is a light-emitting diode and the light-receiving element is a phototransistor.
