A water level indicator, and a self-watering planter containing same. The water level indicator having a top end and a bottom end, and a plurality of pushrods, each of the pushrods comprising an indicator flag cap and a float. The floats on each of the pushrods may each arranged such that the indicator flag cap of each pushrod is pushed towards the top end when liquid container is filled to different levels.

A water level indicator having an upper housing, with a cavity, having a plurality of indicator flag caps disposed within the cavity, and a plurality of pushrods, wherein each indicator flag cap is connect to one of the plurality of pushrods, and each of the pushrods may have a different length. A plurality of floats, each having a locking hole, which receive and secures one of the plurality of pushrods. A first floats of the plurality of floats has a locking tab that secures the second end of a first pushrod, and the float having at least one through hole which allows a second pushrod of the plurality of pushrods to pass through the first float cage and the first float.

A plug for a level indicator system and a level indicator system. The level indicator system includes an elongated level indicator tube sealed by one or more of the plugs, and a magnetically operated visual indicator secured within the elongated level indicator tube. The plug includes an elongated body having a first end, a second end; and port. The plug is configured to form a seal with the level indicator tube.

An automatic surface elevation table (Auto SET) for measuring ground surface movements and land surface subsidence. The Auto SET includes a free-floating foot resting on a sediment surface. A benchmark rod passes through a center of the free-floating foot, and is driven into the sediment surface and extends above the sediment surface. A water level recorder system is attached to the benchmark rod. The water level recorder system includes a water level recorder attached to a top of the benchmark rod, a double block pulley system having an upper end connected to the water level recorder and a lower end connected to the free-floating foot, and a counterweight attached to the upper end of the double block pulley system. The water level recorder system measures movement of the free-floating foot to determine ground surface movements.

A soap dispenser having a soap level indication system includes a soap container with a main volume surrounded by one or more sidewalls, a channel disposed along at least one sidewall of the one or more sidewalls and being fluidically coupled to the main volume of the soap container via a passage, a float structure disposed within the channel and configured to float in a liquid within the soap container, and a level indicator disposed along an exterior surface of at least one sidewall of the one or more sidewalls. The level indicator is located adjacent the float structure. Further, the level indicator and the float structure are magnetically coupled to each other so that the level indicator indicates the location of the float structure within the channel.

A level gauge for determining the level of a liquid in a vessel includes lenticular lens assembly allowing a plurality of level indicator flags enclosed therein to be viewed from a wide angle. The indicator flags have an elongated body manufactured from a sheet of material, and form a central pocket for retaining a magnet, and pins on either end for mounting within a frame. A mounting frame positions the lens assembly whereby an open channel is formed between the lens assembly and a back plate. The mounting frame is mounted to the vessel using spacers forming an open gap between the mounting frame and vessel. The open channel and gap minimize the transfer of heat from the vessel to the level gauge. The passage of a float with a magnet on the liquid in the vessel rotates the flags.
