Abstract

Cost is reduced by simplifying piping work and reducing the number of parts. At the same time, the degree of freedom in the arrangement of piping is raised by making the mounting posture of the piping variable. A pipe assembly unit with built-in sensors is fabricated by integrating a main pipe and multiple branch pipes, which branch from the main pipe and by building, in the multiple branch pipes a flow sensor which detects the flow rate of a fluid flowing through a conduit of each of the branch pipes, and the use of a conventional seal construction using a nipple in connections between the main pipe and the branch pipes is abolished. A pipe adapter having legs is detachably attached to opening ends of the main pipe and the legs are fixed to an installation surface A by changing the orientation of the pipe adapter, whereby the mounting posture of the pipe assembly unit is made variable.
