Abstract
Disclosed herein is a water level indicator for a pontoon tank comprising a float mechanism that comprises a support mechanism that does not move; wherein the main support mechanism is fixedly attached to a manway cover that protects the pontoon tank; an extension system with an extension rod adjustment system that contacts the main support mechanism at a first end and that contacts a float at a second end that is opposed to the first end; and a movable portion that comprises a plurality of levers; wherein the movable portion contacts the main support mechanism and the extension system; and wherein the plurality of levers act cooperatively to displace a gauge rod in proportion to a fluid level in the tank.

A water level indicator for a pontoon tank comprising:
- a float mechanism that comprises:
- a support mechanism that does not move;
- wherein the support mechanism is fixedly attached to a manway cover that protects the pontoon tank;
- an extension system with an extension rod adjustment system that contacts the support mechanism at a first end and that contacts a float at a second end that is opposed to the first end;
- and
- a movable portion that comprises a plurality of levers;
- wherein the movable portion contacts the support mechanism and the extension system;
- and wherein the plurality of levers act cooperatively to displace a gauge rod in proportion to a fluid level in the tank;
- wherein the support mechanism comprises a first vertical beam and a second vertical beam, where the first vertical beam is longer than the second vertical beam;
- a horizontal beam in contact with each of the two vertical beams, a first inclined beam that contacts the first vertical beam;
- and a second inclined beam that contacts the first inclined beam at a distance between ⅓ (one-third) and ½ (one-half) of the distance as measured from the first inclined beams point of contact with the first vertical beam.
A method for manufacturing a water level indicator for a pontoon tank comprising:
- contacting a support mechanism with an extension system and a movable portion that comprises a plurality of levers to form a float mechanism for the pontoon tank;
- wherein the support mechanism is fixedly attached to a manway cover that protects the pontoon tank;
- wherein the extension system comprises an extension rod adjustment system that contacts the support mechanism at a first end and that contacts a float at a second end that is opposed to the first end;
- and
- wherein the movable portion comprises a plurality of levers;
- wherein the movable portion contacts the support mechanism and the extension system;
- and wherein the plurality of levers act cooperatively to displace a gauge rod in proportion to a fluid level in the tank;
- wherein the support mechanism comprises a first vertical beam and a second vertical beam, where the first vertical beam is longer than the second vertical beam;
- a horizontal beam in contact with each of the two vertical beams, a first inclined beam that contacts the first vertical beam;
- and a second inclined beam that contacts the first inclined beam at a distance between ⅓ (one-third) and ½ (one-half) of the distance as measured from the first inclined beams point of contact with the first vertical beam.
A water level indicator for a pontoon tank comprising:
- a float mechanism that comprises:
- a support mechanism that does not move;
- wherein the support mechanism is fixedly attached to a manway cover that protects the pontoon tank;
- an extension system comprising an extension rod that contacts a float at a one end and a gauge rod at an end that is opposed to the end that contacts the float;
- where the support mechanism contacts the extension rod at a mid-section of the extension rod;
- and where a displacement of the float is transmitted to the gauge rod causing the gauge rod to be proportionately displaced;
- where the gauge rod has a scale attached thereto that slides through a passage in the manway cover;
- where the scale provides a visual indication of a height of a fluid in the pontoon tank.
