Abstract
Abstract A flow rate measuring device for use with liquids or appropriate dry materials, comprising a receptacle calibrated to indicate flow rate (e.g. gallons per minute) rather than static volume, and where a specific sampling period (e.g. 5 seconds) is also specified and which establishes the ratio between the collected volume and the flow rate (e.g. 1/12th) thereby enabling a person to obtain a direct reading of the flow rate from a particular source simply by capturing that flow during the specified sampling period and then noting the level of collected material relative to the calibrations. This invention also provides for the inclusion of additional data such as the average costs related to each flow rate and the potential savings at a lower flow rate. For further convenience, the device of this invention may be manufactured from a flexible plastic material that could be folded flat, thus enabling it to be enclosed in a conventional envelope as for mailing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
76 words
A flow rate measuring device comprising: a non-through-flowing receptacle for collecting samples of a flowing media; graduations on said receptacle expressing the volume of flow per basic time period; and a legend, also on said receptacle, specifying a sample collection period that is different from the expressed basic time period; wherein the actual volume at each graduation is different from the expressed volume by the ratio between the sample collection period and the basic time period.
Claim 2
Dependent Claim
76 words
A flow rate measuring device comprising: a non-through-flowing receptacle for collecting samples of a flowing media; graduations on said receptacle expressing the volume of flow per basic time period; and a legend, also on said receptacle, specifying a sample collection period that is different from the expressed basic time period; wherein the actual volume at each graduation is different from the expressed volume by the ratio between the sample collection period and the basic time period.
Claim 3
Dependent Claim
33 words
A flow rate measuring device as described in claim 1, wherein said receptacle is in the form of a bag constructed of flexible plastic material, thin enough to be collapsed and folded flat.
Claim 4
Dependent Claim
70 words
A flow rate measuring device comprising: a non-through-flowing receptacle for collecting samples of a flowing media; graduations on said receptacle calibrated in terms of flow rate; and a legend, also on said receptacle, specifying the duration of time during which said samples would be collected; wherein said graduations include numbers relating to the cost of said media at each flow rate and the potential savings at a lower flow rate.
Claim 5
Dependent Claim
70 words
A flow rate measuring device comprising: a non-through-flowing receptacle for collecting samples of a flowing media; graduations on said receptacle calibrated in terms of flow rate; and a legend, also on said receptacle, specifying the duration of time during which said samples would be collected; wherein said graduations include numbers relating to the cost of said media at each flow rate and the potential savings at a lower flow rate.
Claim 6
Dependent Claim
118 words
A flow rate measuring device comprising: a non-through-flowing receptacle for collecting samples of a flowing media; graduations displayed thereon indicating flow rates expressed as the volume of media that would flow during a basic unit of time; and a legend displayed on said receptacle specifying a period of time, different from said basic unit, during which said samples would be collected, wherein the ratio between the two time periods is defined as the sample period divided by the basic unit of time; and where each graduation is positioned to be coincident with the level surface of a volume of the contained media which is equal to the volume expressed in that graduation, multiplied by the aforementioned time ratio.
Claim 7
Dependent Claim
118 words
A flow rate measuring device comprising: a non-through-flowing receptacle for collecting samples of a flowing media; graduations displayed thereon indicating flow rates expressed as the volume of media that would flow during a basic unit of time; and a legend displayed on said receptacle specifying a period of time, different from said basic unit, during which said samples would be collected, wherein the ratio between the two time periods is defined as the sample period divided by the basic unit of time; and where each graduation is positioned to be coincident with the level surface of a volume of the contained media which is equal to the volume expressed in that graduation, multiplied by the aforementioned time ratio.
Claim 8
Dependent Claim
33 words
A flow rate measuring device as described in claim 4, wherein said receptacle is in the form of a bag constructed of flexible plastic material, thin enough to be collapsed and folded flat.
Claim 9
Dependent Claim
33 words
A flow rate measuring device as described in claim 4, wherein said graduations further indicate average annual costs related to each flow rate, and also the potential savings at a lower flow rate.
Claim 10
Dependent Claim
91 words
A flow rate measuring device comprising: a non-through-flowing receptacle for collecting samples of flowing water; graduations displayed thereon indicating flow rates in gallons per minute; and also a legend specifying a sampling period of 5 seconds; wherein the ratio between the sampling period and the period of time given in the flow rate expression is 5/60; and where each graduation is positioned to be coincident with the surface of a volume of water, within the receptacle, that is equal to the expressed flow rate volume multiplied by the time ratio, 5/60.
Claim 11
Dependent Claim
91 words
A flow rate measuring device comprising: a non-through-flowing receptacle for collecting samples of flowing water; graduations displayed thereon indicating flow rates in gallons per minute; and also a legend specifying a sampling period of 5 seconds; wherein the ratio between the sampling period and the period of time given in the flow rate expression is 5/60; and where each graduation is positioned to be coincident with the surface of a volume of water, within the receptacle, that is equal to the expressed flow rate volume multiplied by the time ratio, 5/60.
Claim 12
Dependent Claim
33 words
A flow rate measuring device as described in claim 7, wherein said receptacle is in the form of a bag constructed of flexible plastic material, thin enough to be collapsed and folded flat.
Claim 13
Dependent Claim
44 words
A flow rate measuring device as described in claim 7, wherein said graduations also include numbers reflecting the annual cost of water and energy at each flow rate, and the amounts that could be saved by restricting the emission to a lower flow rate.
