Abstract

A fluid flow monitor has coaxial conductive annular supports separated by an insulating gasket and connected by a conductive member. One support has a lesser external diameter and a smaller internal diameter than the other to reduce the chance of accidental short circuiting. Wires are attached to each support, a third wire supplies a floating ground to ensure monitor tripping is not caused by a ground fault. Tabs on the inner perimeter of the supports may mount the conductive member.
