An orifice module for a flow switch system has a cylindrical body which is symmetric about a central axis which defines a metering orifice. An axial central hub holds the stem. The hub connects to the cylindrical body by at least three support spokes which forms a plurality of flow channels angularly disposed about the central axis. The module interacts with the flow switch to enhance the function of the flow switch and also reduces turbulence in the fluid flow system.
