Abstract
Abstract A device for measuring the approximate peak flow of a liquid discharge, including a body member having an inlet opening adjacent the top of the member to receive the liquid discharge, and a cavity extending from the inlet opening through the member. A plate extends across the body member in the cavity below the inlet opening, and the plate has an aperture extending through the plate for passage of liquid. A plurality of tubes extend upwardly from the plate toward the inlet opening, with each of the tubes having different lengths and communicating with the remote side of the plate relative the inlet opening for passage of liquid in the tubes through the plate. The device has means for indicating the maximum height of liquid reached in the body member during the liquid discharge for determining the approximate peak flow rate of the discharge. The liquid passes from the body member to a receptacle for collection therein, and the total volume of the discharge may also be determined by indicia on the receptacle.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
168 words
A device for measuring the approximate peak flow rate of a liquid discharge, comprising: a body member having an inlet opening adjacent the top of the member to receive the liquid discharge, and a cavity extending from said inlet opening through the member; a plate extending across The body member in said cavity below the inlet opening, said plate having aperture means extending through the plate for passage of liquid; a plurality of tubes extending upwardly from the plate toward said inlet opening, each of said tubes having different lengths and communicating with the remote side of the plate relative said inlet opening for passing liquid in the tubes through the plate; means intermediate the inlet opening and said plate wettable for indicating the maximum height of liquid reached in the body member during the liquid discharge to determine the approximate peak flow rate of the discharge into the body member; and means for preventing the incoming liquid discharge from directly a substantial portion of the indicating means.
Claim 2
Independent Claim
168 words
A device for measuring the approximate peak flow rate of a liquid discharge, comprising: a body member having an inlet opening adjacent the top of the member to receive the liquid discharge, and a cavity extending from said inlet opening through the member; a plate extending across The body member in said cavity below the inlet opening, said plate having aperture means extending through the plate for passage of liquid; a plurality of tubes extending upwardly from the plate toward said inlet opening, each of said tubes having different lengths and communicating with the remote side of the plate relative said inlet opening for passing liquid in the tubes through the plate; means intermediate the inlet opening and said plate wettable for indicating the maximum height of liquid reached in the body member during the liquid discharge to determine the approximate peak flow rate of the discharge into the body member; and means for preventing the incoming liquid discharge from directly a substantial portion of the indicating means.
Claim 3
Dependent Claim
17 words
The measuring device of claim 1 including means for directing the liquid discharge away from said tubes.
Claim 4
Dependent Claim
50 words
The measuring device of claim 2 wherein said aperture is positioned adjacent a side of the body member, and said directing means comprises, a baffle extending from the other side of the body member above said tubes, said baffle having end edge above the aperture over which the discharge passes.
Claim 5
Dependent Claim
32 words
The measuring device of claim 1 wherein said indicating means comprises, a liquid indicating strip positioned on the inside of said body member and extending from said plate toward said inlet opening.
Claim 6
Dependent Claim
38 words
The measuring device of claim 4 including indicia on the body member indicating the peak flow rate of the liquid discharge determined by the maximum height of liquid reached in the body member as indicated by said strip.
Claim 7
Dependent Claim
51 words
The measuring device of claim 4 including a flange covering and spaced from said strip to shield the strip from the incoming liquid discharge, the lower end of the flange being spaced from the plate to permit entry of liquid between the plate anad material as liquid rises above the plate.
Claim 8
Dependent Claim
23 words
The measuring device of claim 1 including a receptacle communicating with the lower end of the body member for collecting the liquid discharge.
Claim 9
Dependent Claim
36 words
The measuring device of claim 1 wherein said body member has a generally funnel shape, said member including an upper tapered portion defining the inlet opening, and a lower tubular portion containing said plate and tubes.
Claim 10
Dependent Claim
29 words
The measuring device of claim 8 including a baffle extending from the wall of the body member adjacent the juncture of the tapered and tubular portions over said tubes.
Claim 11
Dependent Claim
34 words
The measuring device of claim 1 wherein said body member comprises, a collection member containing the plate and tubes, and a generally funnel-shaped member removably positioned in the upper portion of the collection member.
Claim 12
Dependent Claim
27 words
The measuring device of claim 10 including a curved member secured to the lower end of the funnel-shaped member to direct the discharge away from the tubes.
