Summary:An indicator assembly for indicating how much liquid has passed through a filter inside a 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 passed through the filter so the user can decide when it requires replacing. The indicator assembly is waterproof and suitable for attachment to or placement inside the vessel and submerged in the liquid to be measured. The assembly may include a clear body cover 9, a pcb 4, and sensor probes 8. The cover has a window area to act as a lens for a display which may include LEDs. A battery clip 6 holds the battery in position to provide power for the indicator. The sensor probes may be remain contactless to the liquid. Status indication is displayed by using a motion sensor to give a non-user interaction display based on movement rather than direct contact of user. Some embodiments comprise a light guide pipe to provide LED indication in both the top and bottom halves of the jug/container.
