The invention described herein, is a design that allows the amount of any liquid which is to be filtered, to be monitored while submerged yet remain contactless to the liquid in its measurement to indicate how much liquid has passed through the filter inside the jug/container or cartridge. It can indicate when a filter used in the container/jug holding the liquid has expired or can indicate how much liquid has been through the filter so the user can decide when it requires replacing. The status indication is displayed by using a motion sensor to give a user interaction display based on movement rather than direct contact of user. Currently all water utilize external indicators located on the jugs to monitor the usage of the filter. |
