A magnetic flow meter includes a first spud end, a second spud end, and a sensing area positioned between the first spud end and the second spud end. The sensing area has a wall thickness that is thinner than a thickness of the first spud end and the second spud end. The flow meter can be manufactured via molding while a plug is positioned in at least two holes of the magnetic flow meter. The flow meter can also be manufactured to have a near hermetic seal formed by inserting a flexible printed circuit board in a slit of a gasket and then either compressing a register cup surrounding the tube gasket or driving a pin into a center pin around which the tube gasket is positioned.
