Collector channels are situated in the container projection to collect the fluid to be sampled. One or more vent channels are also provided in the container projection for conveniently venting a reservoir in the container. The present invention with the foregoing collection capability allows the turbidity of the cleansing fluid to be accurately measured without affecting the performance capacity of the sensor. ## Claims ### Claim 1 A turbidity sensor holder system for a machine for cleansing articles, said holder system comprising: a container attached to an outer surface of a wall of said machine for cleansing articles, said container having a projection extending at a predetermined distance away from an inner surface of said wall, said projection including a respective plurality of collector channels situated to collect fluid flowing along said inner surface and at least one vent channel; a reservoir substantially located within said container, said vent channel in said projection situated to vent air out of said reservoir; a reservoir inlet located adjacent to a first end of said container; a reservoir outlet located adjacent to a second end of said container, said reservoir inlet and outlet being in spaced relationship with respect to one another; a turbidity sensor fluidly coupled to said reservoir outlet at a predetermined distance from said reservoir outlet; and a fluid outlet fluidly coupled to said turbidity sensor and located in said wall of said machine for cleansing articles. ### Claim 2 (depends on 1) A holder system in accordance with claim 1 wherein said plurality of collector channels slants in a generally downward direction toward said reservoir. ### Claim 3 (depends on 1) A holder system in accordance with claim 1 wherein said vent channel slants in a generally downward direction away from said reservoir. ### Claim 4 (depends on 1) A holder system in accordance with claim 1 wherein said collector and vent channels are formed between predeterminedly spaced partitions cooperating to block particulates from entering into said collector and vent channels. ### Claim 5 (depends on 1) A holder system in accordance with claim 1 wherein said container is rigidly attached to said outer surface of said wall. ### Claim 6 (depends on 1) A holder system in accordance with claim 1 wherein said reservoir is further comprised of an angled wall located between said reservoir inlet and said reservoir outlet. ### Claim 7 (depends on 1) A holder system in accordance with claim 1 further comprising a respective fluid conduit for coupling said reservoir outlet, said turbidity sensor and said fluid outlet. ### Claim 8 (depends on 7) A holder system in accordance with claim 7 wherein said vent channel slants in a generally downward direction away from said reservoir. ### Claim 9 (depends on 8) A holder system in accordance with claim 8 wherein said plurality of collector channels slants in a generally downward direction toward said reservoir. ### Claim 10 (depends on 9) A holder system in accordance with claim 9 wherein said reservoir is further comprised of an angled wall located between said reservoir inlet and said reservoir outlet. ### Claim 11 (depends on 10) A holder system in accordance with claim 10 wherein said collector and vent channels are formed between predeterminedly spaced partitions cooperating to block particulates from entering into said collector and vent channels. ### Claim 12 (depends on 10) A holder system in accordance with claim 10 wherein said fluid conduit is further comprised of: first, second, third and fourth ends. ### Claim 13 (depends on 12) A holder system in accordance with claim 12 wherein said turbidity sensor is substantially located between said second and said third ends of said fluid conduit such that said third end is located substantially above said second end. ### Claim 14 (depends on 13) A holder system in accordance with claim 13 wherein said container is rigidly attached to said outer surface of said wall. ### Claim 15 A turbidity sensor holder system for a machine for cleansing articles, said holder system comprising: a container attached to an outer surface of a wall of said machine for cleansing articles, said container including a projection extending at a predetermined distance away from an inner surface of said wall, said projection including a respective plurality of collector channels situated to collect fluid flowing along said inner surface and at least one vent channel; a reservoir substantially located within said container, said vent channel in said projection situated to vent said reservoir; a reservoir inlet located adjacent to a first end of said container; a reservoir outlet located adjacent to a second end of said container, said reservoir inlet and outlet being in spaced relationship with respect to one another; a turbidity sensor fluidly coupled to said reservoir outlet at a predetermined distance from said reservoir outlet; a fluid outlet fluidly coupled to said turbidity sensor and located in said wall of said machine for cleansing articles; and a fluid conduit for coupling said reservoir outlet, said turbidity sensor and said fluid outlet. ### Claim 16 (depends on 15) A holder system in accordance with claim 15 wherein said plurality of collector channels slants in a generally downward direction toward said reservoir. ### Claim 17 (depends on 16) A holder system in accordance with claim 16 wherein said vent channel slants in a generally downward direction away from said reservoir. ### Claim 18 (depends on 17) A holder system in accordance with claim 17 wherein said collector and vent channels are formed between predeterminedly spaced partitions cooperating to block particulates from entering into said collector and vent channels. ### Claim 19 (depends on 17) A holder system in accordance with claim 17 wherein said container is rigidly attached to said outer surface of said wall. ### Claim 20 (depends on 19) A holder system in accordance with claim 19 wherein said reservoir is further comprised of an angled wall located between said reservoir inlet and said reservoir outlet. ### Claim 21 (depends on 20) A holder system in accordance with claim 20 wherein said fluid conduit is further comprised of: first, second, third and fourth ends. ### Claim 22 (depends on 21) A holder system in accordance with claim 21 wherein turbidity sensor is substantially located between said second and said third ends of said fluid conduit such that said third end is located substantially above said second end. ### Claim 23 A container for collecting fluid samples in a turbidity sensor holder system for a machine for cleansing articles wherein said container is attached to an outer surface of a wall of said machine for cleansing articles, said container comprising: a projection extending at a predetermined distance away from an inner surface of said wall, said projection including a respective plurality of collector channels situated to collect fluid flowing along said inner surface and at least one vent channel; a reservoir substantially located within said container, said vent channel in said projection situated to vent said reservoir; a reservoir inlet located adjacent to a first end of said container; and a reservoir outlet located adjacent to a second end of said container, said reservoir inlet and outlet being in spaced relationship with respect to one another. ### Claim 24 (depends on 23) A container in accordance with claim 23 wherein said plurality of collector channels slants in a generally downward direction toward said reservoir. ### Claim 25 (depends on 24) A container in accordance with claim 24 wherein said vent channel slants in a generally downward direction away from said reservoir. ### Claim 26 (depends on 23) A container in accordance with claim 23 wherein said collector and vent channels are formed between predeterminedly spaced partitions cooperating to block particulates from entering into said collector and vent channels. ### Claim 27 (depends on 26) A container in accordance with claim 26 wherein said reservoir is further comprised of an angled wall located between said reservoir inlet and said reservoir outlet.
