Abstract
Abstract A totalization meter system for a water treatment device, the device having an inlet aperture and an outlet aperture, and a channel for channeling water between the inlet and outlet apertures. A flow reactive device is positioned in the channel and is exposed to the flowing water, and a signal generating member is positioned on the flow reactive device. A switch is positioned proximately to the flow reactive device, and is sensitive to the proximity of the signal generating member. The switch is able to communicate electric signals indicative of the motion of the signal generating member. A resettable processor having a performance threshold programmed therein and an output device is included. The microcontroller is in electrical communication with the switch for receiving electrical signals from the switch. The switch is capable of sensing the characteristics of the flow reactive device and communicates electrical signals representative of the characteristics to the microcontroller. The microcontroller interprets the signals as a first performance data. The microcontroller compares the first performance data against the respective performance threshold in the microcontroller to determine if the performance threshold has been surpassed, and if surpassed actuates the output device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
266 words
A water treatment device for attachment to the end of a faucet to filter water flowing from the faucet, said water treatment device comprising: a housing defining an upright portion and a portion extending laterally from the bottom of the upright portion; an inlet formed in the top of said laterally extending portion configured to attach to the faucet; a bypass outlet formed in the bottom of said laterally extending portion; a filtered outlet formed in the bottom of the upright portion; a non-filtered bypass flow path defined in fluid communication between said inlet and said bypass outlet; a filtered flow-path defined in fluid communication between said inlet and said filtered outlets; a valve attached to said laterally extending portion and selectively positionable to direct water flow either through said non-filtered bypass flow path or said filtered flow-path; a filter positioned in said upright portion, and in the filtered flow-path to filter said water flowing through said filtered flow-path; a meter system positioned in a bottom region of said upright portion and below said filter, in said filtered flow-path, to meter the water flowing through said filtered flow-path; and said filtered flow-path extending in a first leg laterally from said inlet in said laterally extending portion and into said bottom region of said upright housing adjacent said meter system, and turning to extend upwardly adjacent said meter system to direct water to said filter said filtered flow-path continuing through said filter and extending in a second leg downwardly from said filter through said bottom portion of said housing adjacent said meter system to said filtered outlet.
Claim 2
Dependent Claim
266 words
A water treatment device for attachment to the end of a faucet to filter water flowing from the faucet, said water treatment device comprising: a housing defining an upright portion and a portion extending laterally from the bottom of the upright portion; an inlet formed in the top of said laterally extending portion configured to attach to the faucet; a bypass outlet formed in the bottom of said laterally extending portion; a filtered outlet formed in the bottom of the upright portion; a non-filtered bypass flow path defined in fluid communication between said inlet and said bypass outlet; a filtered flow-path defined in fluid communication between said inlet and said filtered outlets; a valve attached to said laterally extending portion and selectively positionable to direct water flow either through said non-filtered bypass flow path or said filtered flow-path; a filter positioned in said upright portion, and in the filtered flow-path to filter said water flowing through said filtered flow-path; a meter system positioned in a bottom region of said upright portion and below said filter, in said filtered flow-path, to meter the water flowing through said filtered flow-path; and said filtered flow-path extending in a first leg laterally from said inlet in said laterally extending portion and into said bottom region of said upright housing adjacent said meter system, and turning to extend upwardly adjacent said meter system to direct water to said filter said filtered flow-path continuing through said filter and extending in a second leg downwardly from said filter through said bottom portion of said housing adjacent said meter system to said filtered outlet.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
47 words
A water treatment device as defined in claim 1, wherein said filtered flow path from adjacent said meter system to said filter turns to extend substantially vertically upwardly; and said filtered flow-path adjacent said meter system from said filter extends substantially vertically downwardly to said filtered outlet.
Claim 5
Dependent Claim
75 words
A water treatment device as defined in claim 1, wherein said filter is encased in a filter housing to form a filter cartridge having a bottom end, and an inlet port and an outlet port formed in said bottom end of said filter housing, said inlet port positioned in said bottom end at a location spaced radially outwardly from said outlet port to engage said first leg and second leg of said filtered flow-path, respectively.
Claim 6
Dependent Claim
