Liquid level indicator

A self-watering planter comprising:

• an internal wall and floor defining a plant cavity;
• an external wall surrounding a water reservoir;
• an inlet capable of allowing water to enter the water reservoir;
• and
• a water level indicator comprising
• an upper housing, comprising a cavity, wherein a plurality of indicator flag caps are disposed;
• a plurality of pushrods, each of the pushrods has a first end and a second end defining a length that is different from the lengths of the other pushrods in the plurality of pushrods, and wherein the first end of each pushrod in the plurality of pushrods is connect to a different indicator flag cap;
• a plurality of floats, wherein each float comprises a locking hole, which receives and secures a second end of one of the plurality of pushrods;
• and
• a first float cage of the plurality of floats, wherein the locking hole of the first float secures the second end of a first pushrod of the plurality of pushrods, and the first float comprises at least one through hole which allows a second pushrod of the plurality of pushrods, to pass through the first float.

A water level indicator comprising:

• an upper housing, comprising at least three cavities, including a first cavity, a second cavity and a third cavity, wherein an indicator flag caps is disposed within each cavity in the upper housing;
• at least three pushrods, including a first pushrod, a second pushrod and a third pushrod, wherein each of the pushrods has a first end and a second end defining a length that is different from the lengths of the other pushrods in the plurality of pushrods, such that the length of the first pushrod is shorter than the length of the second pushrod, and the length of the second pushrod is shorter than the length of the first pushrod, and wherein the first end of each pushrod in the plurality of pushrods is connect to a different indicator flag cap, such that the first end of the first pushrod is connected to the indicator flag in the first cavity of the upper housing, the first end of the second pushrod is connected to the indicator flag in the second cavity of the upper housing, and the first end of the third pushrod is connected to the indicator flag in the third cavity of the upper housing;
• a plurality of floats, including a first float, a second float and a third float;
• a plurality of float cages, including a first float cage, a second float cage and a third float cage, wherein each float in the plurality of floats is disposed within one of the plurality float cages, such that the first float is disposed in the first float cage, the second float is disposed in the second float cage, and the third float is disposed in the third float cage;
• wherein each float cage comprises a locking hole, which receives and secures a second end of one of the plurality of pushrods such that the first float cage receives and secures the first pushrod in its locking hole, the second float cage receives and secures the second pushrod in its locking hole, and the third float cage receives and secures the third pushrod in its locking hole;
• and
• the first float cage and a first float each comprise at least two through holes which allows the second pushrod and third of the plurality of pushrods, to pass through the first float cage and the first float, and the second float cage and second float comprise at least one through hole, which allows the third pushrod to pass through the second float cage and the second float.
