    SALT WATER POOL CHLORINATOR HAVING A SENSOR Technical Field The present disclosure generally relates to a salt water pool chlorinator having a 5 sensor. The sensor finds application specifically, though not exclusively, to salt water pool chlorination. The salt water pool chlorinator may be in the form of a unit and may additionally have a feeder or extractor. Background 10 Salt water pool chlorination involves electrolysis of at least one of sodium chloride and sodium bromide ("salt") dissolved in pool water to produce sanitizing agents such as hypochlorous acid and sodium hypochlorite. The electrolysis is achieved by passing a current through adjacent conductive plates immersed in the pool water. i5 Optimal operation of a salt water chlorinator can require the concentration of dissolved salts in the pool water be in the range of 1,800 and 6,000 parts per million, and that a concentration of stabilizers, such as cyanuric acid, when present are at appropriate levels. The pH of the pool water may also need to be maintained at an appropriate level. 20 In order to determine the concentration of chemicals in a pool, a person may employ so-called "test strips" or fill a container with a sample of pool water and subsequently test the water in the container. US 7879208 discloses a multi-port chlorine generator comprising sensors, located in one of the ports, for monitoring water parameters. 25 The above references to the background art do not constitute an admission that the art forms part of the common general knowledge of a person of ordinary skill in the art. The above references are also not intended to limit the application of the unit and method disclosed herein. 30 Summary of the Disclosure In a first aspect there is disclosed a unit for a salt water pool chlorinator. The unit is arranged for water to flow through the unit. The unit is configured for an 4238057_1 (GHMatters) P88361.AU.1 - 2 electrode assembly to be received therein and is arranged such that some of the water flows through the electrode assembly. The unit has a channel, defined by a barrier impermeable to water, arranged for some other of the water to flow through the channel. At least one port is arranged at the channel whereby at least one of a sensor, a 5 feeder and/or an extractor is able to use the port to respectively detect, feed into and/or extract water in the channel. By providing in the unit a separate water flow through the channel (i.e. separate to the water that flows through the electrode assembly), electrolysis can occur independently of sensing, feeding and/or extracting. Such an arrangement may, for 10 example, allow a sensor in the channel to detect parameters that have not been altered by electrolysis. This is in contrast to US 7879208, wherein the electrodes are configured to be in-line with the sensors. Furthermore, the sensors in US 7879208 are not located in a channel that is separate to the electrodes, let alone in a channel that is defined by a barrier that is impermeable to water. Therefore, in US 7879208 the 15 detecting of parameters and the electrolysis are not performed on separate water flows. The at least one port can be configured such that a sensor may be arranged to determine a concentration of a dissolved salt in the water when so flowing through the channel. Although, the sensor may alternatively be configured to measure any of: acidity; alkalinity; total alkalinity; biguanide; bromine; free bromine; chloride; chlorine; 20 free chlorine; free and combined chlorine; conductivity; copper; cyanuric acid; hardness; calcium hardness; total hardness; hydrogen peroxide; iron; manganese; mineral/salt; monopersulfate; NaCl (salt); nitrate; oxidation reduction potential (ORP); ozone; pH; phosphate; quaternary ammonium compounds (QAC); and generally any chemical present in the water. Further, a number of sensors may be provided in one or 25 more ports, with each sensor being configured to measure any of the above mentioned parameters. The sensor may make it unnecessary for a person to manually take a sample of the water and subsequently measure the sample at a location remote from the pool. The measurement may not require a person. The measurement may be continuously or 30 regularly initiated by a processor. The processor may cause a chemical for a pool, to be introduced through the feeder. The processor may control the injection of the chemical through the feeder in response to a concentration determined by the sensor. Examples 4238057_1 (GHMatters) P88361.AU.1 - 3 of chemicals for a pool include but are not limited to: sodium bicarbonate; sodium carbonate; sodium bisulphate; sodium hypochlorite; chlorine; hydroxyethylidene diphosphonic acid complex; calcium chloride; hydrochloric acid; trichloroisocyanuric acid; sodium tetraborate pentahydrate; cyanuric acid; copper sulphate pentahydrate; s boric acid; sodium dichloroisocyanurate dihydrate; calcium hypochlorite; potassium peroxymonopersulphate; aluminium sulphate; natural clarifier; cationic polyectrolyte; aluminium chlorhydrate; aluminium oxide; poly[oxyethylene(dimethyliminio)ethylene (dimethyliminio)ethylene dichloride]; cupric ammonium complex; benzalkonium chloride; copper - triethanolamine complex (as copper); quaternary ammonium io chloride; isocyanuric acid; sodium metabisulphite; 1-hydroxyethylidene- 1,1 diphophonic acid; citric acid monohydrate; oxalic acid; magnesium sulphate heptahydrate; and aluminosilicate. In one embodiment, the unit may further comprise an electrode assembly receptacle. The electrode assembly receptacle may be arranged for the electrode is assembly to be received therein, with the receptacle as a whole being received in the unit. In embodiments where the electrode assembly receptacle is not present in the unit, the unit itself may be considered to be the electrode assembly receptacle. While a barrier, or partition, may be provided to define the channel, it may not be necessary to have a dedicated barrier, or partition, within the unit to define the 20 channel. In lieu of a dedicated barrier, the channel may at least partially be defined by a wall of the electrode assembly, when received in the unit, or a wall of the electrode assembly receptacle when present in the unit. Alternatively, the channel may be defined by both a wall of the electrode assembly and a wall of the electrode assembly receptacle. In a further embodiment the channel may be defined by a surface or 25 surfaces of only one of the electrode assembly, electrode assembly receptacle or unit, or it may be defined by any combination of surfaces of these components. Such an arrangement may simplify the structure and manufacture of the unit. The electrode assembly, or the electrode assembly receptacle with the electrode assembly arranged therein, may be easily removed from the unit (when worn out, for 30 example), rather than removing the entire unit. This may reduce or eliminate the need for skilled labour (by an electrician or plumber for example), when replacing a worn out electrode assembly. 4238057_1 (GHMatters) P88361.AU.1 - 4 In an embodiment, the unit may have an inlet for water to enter into the unit and an outlet for water to leave the unit. The channel may be laterally displaced with respect to an axis shared by the inlet and the outlet. In this regard, the channel may, for example, be defined by a sump of the unit. 5 Alternatively, the channel may be disposed laterally (e.g. to a side) of the electrode assembly. In a further alternative, the channel may be disposed above the electrode assembly. The electrode assembly may have an electrode plate that is parallel to the axis. Alternatively, the electrode assembly may have an electrode plate that is perpendicular to the axis. 10 In an embodiment, the channel may be arranged such that some of the water when so flowing through the unit is split between the electrode assembly and the channel. In an embodiment, the unit may be arranged for the electrode assembly to be removably received therein. The unit may comprise an electrode assembly port is arranged for the electrode assembly to be passed therethrough. The electrode assembly port may be arranged to receive a closure that seals the port when so received. In a second aspect there is disclosed a unit for a salt water pool chlorinator. The unit is arranged for water to flow through the unit. The unit comprises an electrode 20 assembly port in a wall of the unit, so that an electrode assembly may be removably received in the unit via the electrode assembly port. A channel is defined by a wall of the unit and a wall of the electrode assembly when the electrode assembly is received in the unit. The electrode assembly is arranged for some of the water to flow therethrough and the channel is arranged for some other of the water to flow therethrough. The unit 25 further comprises at least one port arranged at the channel. At least one of a sensor, a feeder and/or an extractor is able to use the port to respectively detect, feed into and/or extract water in the channel. The unit disclosed in the second aspect may be otherwise as defined in the first aspect. 30 In a third aspect, a unit for a salt water pool chlorinator is disclosed. The unit is arranged for water to flow through the unit. The unit comprises an electrode assembly 4238057_1 (GHMatters) P88361.AU.1 - 5 port in a wall of the unit, so that an electrode assembly may be removably received in the unit via the electrode assembly port. A channel is defined by a wall of the unit and a wall of the electrode assembly when the electrode assembly is received in the unit. The electrode assembly is arranged for some of the water to flow therethrough and the 5 channel is arranged for some other of the water to flow therethrough. The unit further comprises at least one of a sensor, a feeder and/or an extractor located at the channel to respectively detect, feed into and/or extract water in the channel. The electrode assembly may be secured into the electrode assembly port by various suitable forms of securing mechanisms, including a 1/4 turn-type fastening 10 mechanism, a screw-type mechanism, a threaded mechanism, or a bayonet-type fastening mechanism. The unit disclosed in the third aspect may be otherwise as defined in the first or second aspect. is In a fourth aspect, a method of accessing pool water is disclosed. The method comprises one or more of: detecting, feeding into and/or extracting water in the channel, such as through the at least one port arranged at the channel of an installed unit for a salt water pool chlorinator, as described above in the first, second and third aspects. 20 In an embodiment, the method comprises the step of installing the unit for a salt water pool chlorinator. In a fifth aspect, a method of treating pool water flowing through a unit is disclosed. The method comprises subjecting the pool water to electrolysis in one part 25 of the unit, and detecting, feeding into and/or extracting water in another part of the unit. In an embodiment, the method comprises the use of a salt water pool chlorinator as described above in the first, second and third aspects. 30 Brief Description of the Drawings Notwithstanding any other forms which may fall within the scope of the unit and method as set forth in the Summary, specific embodiments of a unit and method for a 4238057_1 (GHMatters) P88361.AU.1 - 6 salt water pool chlorinator will now be described, by way of example only, with reference to the accompanying Figures in which: Figure 1 shows an elevational view of an embodiment of a unit for a salt water pool chlorinator; s Figure 2 shows a section view of the embodiment of the salt water pool chlorinator shown in Figure 1; Figures 3 to 5 show schematic views of various example sensors at a port of the unit; Figure 6 shows a simplified cross sectional view of another embodiment of a 10 unit for a salt water pool chlorinator with an electrode assembly removed; Figure 7 shows the unit for a salt water pool chlorinator of Figure 6 but with the electrode assembly received therein; Figure 8 shows a perspective view of another embodiment of a unit for a salt water pool chlorinator; is Figure 9 shows a section view taken on line A-A of the embodiment of the salt water pool chlorinator shown in Figure 8; Figure 10 shows a section view taken on line B-B of the embodiment of the salt water pool chlorinator shown in Figure 8; Figure 11 shows an exploded perspective view of the salt water pool chlorinator 20 of Figure 8; Figure 12 shows an exploded perspective view of yet another embodiment of a unit for a salt water pool chlorinator; Figure 13 shows an exploded perspective view of yet a further embodiment of a unit for a salt water pool chlorinator; 25 Figures 14 shows a 1/4 turn-type closure; Figure 15 shows a closure fastened with screws; Figure 16 shows a threaded closure; and Figure 17 shows a bayonet-type closure. 30 Detailed Description of Specific Embodiments Figures 1 and 2 show an embodiment of a unit for a salt water pool chlorinator, the unit generally being indicated by the numeral 10. The unit 10 has an inlet 12 for 42380571 (GHMatters) P88361.AU.1 water to enter the unit 10, and an outlet 14 for water to leave the unit 10. The unit is installed in a pipe 11 that, in use, communicates water from the pool to a pool water pump. The unit is arranged for water to flow through the unit. The unit 10, in this but not necessarily all embodiments, has an injection 5 moulded housing 16. The housing 16 may be made of any suitable injection moulded polymer including but not limited to epoxy, phenolic, nylon, polystyrene, ABS, polycarbonate and polypropylene. In this embodiment the housing is made of an opaque plastic. The housing may alternatively be transparent. The housing may be any suitable material suitably formed. 10 The housing 16 has an electrode assembly receptacle 18. The electrode assembly receptacle 18 is arranged for an electrode assembly 20 to be received therein, and has a base 19 which is impermeable to water. In this form the electrode assembly comprises a set of electrode plates, however in other forms the electrode assembly may not be limited to electrode plates and, for example, may further comprise a casing or 15 support structure for the electrode plates. The electrode assembly receptacle 18 is located between the inlet 12 and the outlet 14 such that some of the water that enters the inlet 12 flows through the receptacle 18 and thus across the conductive plates of the electrode assembly 20. The arrangement of the electrode assembly between the inlet and the outlet defines the 20 configuration of the unit as "in-line". The electrode assembly when connected to an active electrical source, such as an electrical grid, electrolyses the sodium chloride and/or sodium bromide in the water that enters the inlet 12 and flows across the plates of the electrode assembly 20. The electrolysis generates the sanitizing agents (such as chlorine and/or bromine etc.) in the 25 pool water flowing through the unit. Electrical contacts 24, 26 and 28, for connection with the electrical source, protrude upwardly through a closure 22. The housing 16 of the unit 10 has a depending portion, in the form of a sump 30. The sump 30, in conjunction with the base 19 of the electrode assembly receptacle 18, defines an internal space which, in this embodiment, is in the form of a channel 32. In 30 this but not necessarily all embodiments, the channel 32 is an extension of the space defined by the housing 16. In other embodiments, however, the channel may be formed by a tube or pipe; one end of the tube being in communication with the water inlet 12, 4238057_1 (GHMatters) P88361.AU.1 - 8 and the other end being in communication with the water outlet 14. In yet another embodiment, the channel may be formed by an internal rebate, groove or gutter located between the inlet 12 and the water outlet 14. Generally, any suitable channel configuration may be used. 5 The inlet 12 and outlet 14 share an axis 34. In this embodiment, the channel is laterally displaced with respect to the axis 34. In alternative embodiments, however, the channel 32 may be intersected by the axis and it may be the electrode assembly that is laterally displaced with respect to the axis. In yet another embodiment, both the channel and the electrode assembly are laterally displaced with respect to the axis 34. 10 The electrode plates of the electrode assembly 20 are parallel with the axis 34 so that the water flows freely between the plates with minimal disturbance. In other embodiments, the electrode plates are orientated across the axis 34 and act to disrupt the flow of the water from the inlet 12 to the outlet 14. In yet another embodiment, the plates may be angled to the direction of the water flow. The resulting turbulent flow is may improve the electrolysis. Generally, any suitable orientation of the electrode assembly may be used. The channel 32 is shown, in this embodiment, having a plurality of ports 36, 38, 40 and 44. At port 36 is a sensor 46. In this embodiment, the sensor is in the form of a salt sensor which can detect the concentration of sodium chloride and/or sodium 20 bromide in the pool water flowing through the channel. This and other sensors may be in communication with a processor via a cable or wireless connection, for example. The sensor information generated by the sensor 46 may be received by the processor unit in communication with the sensor 46. The processor unit may process the sensor information and display the concentration (or some indication of the concentration), or 25 use the sensor information to adjust the concentration of the sensed chemical. For example, if the sensor information indicates that the sodium chloride (or sodium bromide) levels are too low, the processor may cause concentrated sodium chloride (or sodium bromide) to be injected through port 38 via a feeder 48. At port 40 a pH sensor 50 is inserted into the channel 32. The sensor 30 information generated by sensor 50 may be sent to the processor which may process the information. The processor may display an indication of the pH on a display and/or cause a feeder 52 in port 42 to inject at least one of (but not limited to) a buffer, an acid, 4238057_1 (GHMatters) P88361.AU.1 - 9 and an alkaline solution to appropriately adjust the pH. At port 44 is an extractor 54. Extractor 54 may comprise an inlet, and may be arranged to be attached to a conduit which can take a sample of the water in the channel 32 and deliver it to another place. For example, extractor 54 may be in communication s with a remotely located sensor, for example a sensor adjacent or at the processor. Alternatively, the extractor 54 may extract water from the channel 32 and communicate it to a mixer which mixes the extracted water with a chemical and then reintroduces the water into the channel through a feeder as appropriate. Generally, the extractor may be used for any suitable purpose. 10 Figures 3 to 5 show various configurations of sensors at one of the ports, in this case port 36. The sensor 46 is secured to the port 36 by a screw thread 56. In other embodiments, alternate or additional sensor fastening mechanism may be used such as bayonet fastening, a clip, a screw, an adhesive, or generally any suitable fastening mechanism. Feeders and extractors may be similarly secured. The active sensor tip 58 is may be recessed within a cowl 60 of the sensor 46 as shown in Figure 2. Alternatively, as shown in Figure 3, the sensor tip 58 may be flush with the opening of the cowl 60. Alternatively, as shown in Figure 4, the sensor tip 58 may protrude out of the cowl 60 and into the channel 32. Returning to Figure 1, the unit 10 is arranged for the electrode assembly 20 to be 20 removably received therein. The unit 10 has an assembly port generally indicated by the numeral 62 which is closed by a closure 64. The closure has a screw thread which can be threaded onto a corresponding thread on a rim of the port. To insert or remove the electrode assembly 20, the closure 64 is screwed off to reveal the open port 62 through which the electrode assembly is passed. Generally, the closure may be any 25 suitable closure and may be alternatively or additionally fastened to the port using any suitable mechanism, such as a 1/4 turn configuration, screws, threaded, or bayonet-type configuration. These options for securing the closure are respectively shown in Figures 14 to 17. Other suitable fastening mechanisms may also include clips or straps. Costs associated with replacing the electrode assembly or the need for skilled labour may be 30 avoided or reduced. Accordingly, the port may be configured such that an unskilled person may remove and insert the electrode assembly. The underside of the closure 64 may have attached thereto a gasket in the form 4238057_1 (GHMatters) P88361.AU.1 - 10 of a resilient material, examples of which include but are not limited to rubber and silicone. Alternatively, the gasket need not be attached to the closure and may be in the form of an O-ring seal, for example. To install the unit 10, a pipe 11 that in use communicates water from the pool to 5 a pool water pump may be cut to expose two pipe ends that are coupled to the unit by collar portions 13 and 15. In other embodiments, flexible tubes may be slipped over the pipe ends and the inlet 12 and outlet 14. Constricting collars or clamps may fasten the tubes to the pipe ends. In other embodiments, the pipe ends may be dimensioned to snugly fit within the inlet and outlet. An adhesive may be applied to the outside surface io of the pipe ends which are then inserted to the respective inlet or outlet. Alternatively, the two pipe ends may be dimensioned to fit over the inlet or outlet. Generally, the unit may be installed by any suitable mechanism. Figures 6 and 7 show a simplified cross sectional view of another embodiment of a unit 100, wherein parts of similar form and/or function to those in Figure 1 are is similarly numbered. Figure 6 shows a unit 100 with the electrode assembly 20 removed, whereas Figure 7 shows the electrode assembly 20 received by the housing 16. In this embodiment, the closure 64 is attached to the electrode assembly 20 to form a cartridge 102. An outward facing surface 104 of the cartridge is threaded and mates with a correspondingly threaded surface 106 at the rim 108 of the assembly port 62. 20 Generally, the cartridge 102 may be coupled to the port using any suitable mechanism as described above. Sensors, feeders and extractors may be coupled to a sump 110. Figures 8 to 11 show various views of another embodiment of a unit for salt water pool chlorinator, the unit being generally indicated by the numeral 200. Parts similar in form or function to those of the embodiment of Figure 1 are similarly 25 numbered. The electrode assembly 20 has been received by the electrode assembly receptacle 18 of the housing 16 of unit 200. In this embodiment, the channel 32 is defined by a wall 33 of the electrode assembly receptacle 18 and a wall 35 of the housing 16. Furthermore, the channel in this embodiment is not at the bottom, but to one side. Sensors such as 46 and 50 sense properties of water in the channel 32. 30 Figure 12 shows an exploded perspective view of another embodiment of a unit for a salt water pool chlorinator, the unit being generally indicated by the numeral 300. Parts similar in form or function to those of the embodiment of Figure 1 are similarly 42380571 (GHMatters) P88361.AU.1 - 11 numbered. The electrode assembly 20 is again received in the receptacle 18 of the housing 16 of unit 300. However, in this embodiment, the channel 32 is defined within a cover 302 for the electrode assembly receptacle 18, whereby the channel is able to be located in use above the electrode assembly receptacle. The cover 302 is secured to the 5 receptacle 18 by a collar 304 (e.g. which connects to a rim 306 of the receptacle 18 via a screw- or bayonet-fitting, etc). Thus, the channel lifts out, as such, together with the top-removable/insertable electrode assembly 20. Top-mounted sensors such as 46 and 50, having a squat configuration, again sense properties of water in the channel 32. Figure 13 shows an exploded perspective view of yet another embodiment of a 10 unit for salt water pool chlorinator, the unit being generally indicated by the numeral 400. Parts similar in form or function to those of the embodiment of Figure 1 are similarly numbered. The electrode assembly 20 is again received in the receptacle 18 of the housing 16 of unit 400. Again, in this embodiment, the channel 32 is defined within a cover 402 for the electrode assembly receptacle 18, whereby the channel is 15 able to be located in use above the electrode assembly receptacle. The cover 402 is again secured to the receptacle 18 by a collar 404 (e.g. which connects to a rim 406 of the receptacle 18 via a screw- or bayonet-fitting, etc). Thus, in this embodiment the channel also lifts out together with the top-removable/insertable electrode assembly 20. Top-mounted sensors such as 46 and 50, again having a squat configuration, sense 20 properties of water in the channel 32. While a number of specific embodiments of a unit and method have been described, it should be appreciated that the unit and method may be embodied in many other forms. In the claims which follow, and in the preceding description, except where the 25 context requires otherwise due to express language or necessary implication, the word "comprised" in variations such as "comprises" or "comprising" are used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude presence or addition of further features in various embodiments of the unit and method as disclosed herein. 4238057_1 (GHMatters) P88361.AU.1
