Abstract
Abstract A fluid manifold, to which high-pressure steam may be supplied, has coupled thereto a row of individually valved branch pipes each of which terminates in a respective leaky component (which produces a steam leak). A rotameter coupled to the manifold measures the quantity of steam escaping through a selected, typical leaky component. The assembly is arranged to be easily transportable.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
69 words
Apparatus for exhibiting steam quantity leakage from a leaky component comprising a transportable steam flow conduit, means coupling said component to said conduit, means fOr connecting said conduit to a source of steam, and means coupled to said conduit for measuring and indicating the quantity of steam flowing through said conduit, and thence through said leaky component, in monetary units per year, based on a preestablished incremental steam cost.
Claim 2
Dependent Claim
69 words
Apparatus for exhibiting steam quantity leakage from a leaky component comprising a transportable steam flow conduit, means coupling said component to said conduit, means fOr connecting said conduit to a source of steam, and means coupled to said conduit for measuring and indicating the quantity of steam flowing through said conduit, and thence through said leaky component, in monetary units per year, based on a preestablished incremental steam cost.
Claim 3
Dependent Claim
68 words
Apparatus for exhibiting fluid quantity leakage from a selected one of a plurality of leaky components comprising a transportable fluid flow conduit, individual means for coupling each of said leaky components to said conduit, means for connecting said conduit to a fluid source, and means coupled to said conduit for measuring and indicating the quantity of fluid flowing through said conduit and thence through the selected leaky component.
Claim 4
Dependent Claim
68 words
Apparatus for exhibiting fluid quantity leakage from a selected one of a plurality of leaky components comprising a transportable fluid flow conduit, individual means for coupling each of said leaky components to said conduit, means for connecting said conduit to a fluid source, and means coupled to said conduit for measuring and indicating the quantity of fluid flowing through said conduit and thence through the selected leaky component.
Claim 5
Dependent Claim
25 words
Apparatus set forth in claim 2, wherein each of said coupling means comprises a valved pipe connected between each respective leaky component and said conduit.
Claim 6
Dependent Claim
73 words
Apparatus for exhibiting fluid quantity leakage from a selected one of a plurality of leaky components comprising a transportable fluid flow conduit, individual means for coupling each of said leaky components to said conduit, means for connecting said conduit to a fluid source, and a rotameter, responsive to fluid flow, coupled to said conduit for measuring and indicating the quantity of fluid flowing through said conduit and thence through the selected leaky component.
Claim 7
Dependent Claim
73 words
Apparatus for exhibiting fluid quantity leakage from a selected one of a plurality of leaky components comprising a transportable fluid flow conduit, individual means for coupling each of said leaky components to said conduit, means for connecting said conduit to a fluid source, and a rotameter, responsive to fluid flow, coupled to said conduit for measuring and indicating the quantity of fluid flowing through said conduit and thence through the selected leaky component.
