Abstract
An apparatus for controlling the flow of fluid through a conduit is disclosed. The conduit permits normal flow of fluid through the conduit and detects abnormal flow of fluid which is due to a catastrophic failure of the fluid system or is due to intermittent flow of fluid caused by a leak in the fluid system. The apparatus is particularly useful in determining the abnormal flow of fluid through conduits where the normal flow of flow is erratic. The apparatus can be modified to change the parameters defining abnormal flow in the system.
