Abstract: A rupturable fluid flow indicator and a rupture disk assembly including the indicator are provided. The indicator is comprised of a rupturable member adapted to be clamped across a fluid flow passageway having at least one opening formed therein for weakening a portion of the member. An electric current conductor adapted to be electrically connected in an alarm circuit is attached across the weakened portion of the rupturable member whereby when the member ruptures as a result of fluid pressure exerted thereon, the conductor also ruptures.

Abstract: A reverse buckling rupture disk apparatus, adapted to be clamped between inlet and outlet companion bolted flanges, the operation of which is unaffected by the torque applied to the bolts of the companion flanges. The apparatus is comprised of a reverse buckling rupture disk which is welded at its periphery to an annular support ring. The annular support ring is in turn welded to an annular support member. Methods of manufacturing the apparatus are also provided.
