摘要：
The present invention relates to a flow tube which supplies liquid fluid used in an irrigation facility and, more specifically, to a liquid sensing flow tube which is able to prevent air from being mixed in a flow path by including a liquid sensor capable of noticing whether liquid fluid exists or not, and an electronic valve of being operated by the signal of the liquid sensor. The liquid sensing flow tube includes: a storage which stores the liquid fluid; a conduit which receives the liquid fluid from the storage and has a flow path where the liquid fluid is able to pass; a liquid sensor which is arranged inside or outside the conduit and senses whether the liquid fluid exists or not in the flow path of the conduit; a sensing circuit unit which processes a signal generated in the liquid sensor and converts the signal into an operation signal of the electronic valve; and the electronic valve which is able to open and close the flow path through the signal converted in the sensing circuit unit.
