Abstract
A sensor body has an orifice forming a central fluid flow passage therethrough and supports a thin conducting frangible rod, such as graphite, across the central fluid flow passage. The graphite rod and connectors are insulated from the body when the body is made from a conducting material such as metal. When the graphite rod is broken by fluid flow, a circuit is broken and an alarm condition is created.
