Claim:
A flow detector comprising: a main body including: (i) a block body, which has an inlet and an outlet and which forms a given path, and (ii) a flow sensor which is attached to the block body to detect a flow rate of a fluid running through said path; a circuit board having mounted thereon an electric circuit which measures the flow rate of the fluid running through said path by using said flow sensor; and a flow regulating valve which regulates the flow rate of the fluid running through said path; wherein said main body and said circuit board are accommodated in a rectangular parallelepiped or cubic housing, which is fixable to a given panel; wherein said flow-regulating valve is mounted on an upper surface of the block body and the flow sensor is mounted on a surface of the block body which is different from the upper surface of the block body; wherein an indicator and an operation switch are provided in a front surface portion of said housing that is exposed at a front surface of said given panel when said housing is fixed to said given panel; wherein said inlet and said outlet of said path are provided in a back surface portion of said housing; and wherein a terminal for external connection of said circuit board is provided in the back surface portion of said housing.
