PROBLEM TO BE SOLVED: To provide a flow detection apparatus of a simple structure capable of reliably fixing a panel-mount-type flow detection unit to a dedicated case. SOLUTION: The apparatus is provided with both the panel-mount-type flow detection unit in which a channel block body with an attached flow sensor is built in an approximately rectangular parallelepiped case and the box-like dedicated case for housing the flow detection unit and using the flow detection unit in a state not mounted to a panel. By helically engaging a screw with a screw hole provided for the channel block body of the flow detection unit for fixing the channel block body to the case from the outside of the case via the case from the outside of the dedicated case, the flow detection unit is fixed to the dedicated case.
