AI Technical Summary

Technical Problem

Existing liquid level gauges for non-transparent tanks fail to provide direct visual reflection of the liquid level outside the tank.

Method used

A magnetic float inside the tank is coupled with an external indicator, using magnets with specific gravity adjusted to match the liquid level, and mechanisms like strings or fences to maintain alignment, ensuring external visibility.

Benefits of technology

Facilitates easy and accurate external visualization of liquid levels by maintaining alignment between internal and external magnets, enhancing readability.

Abstract

To simply and directly reflect a liquid amount in a tank to the outside by a liquid amount meter for the tank which is not transparent.SOLUTION: The liquid amount in the tank is reflected to the outside by the inner and outer magnets. A float with a magnet is floated on the liquid surface of a tank, and a pipe filled with water and a float filled with a magnet having a specific gravity close to 1 are installed on the outside so as to be interlocked with each other.SELECTED DRAWING: None

Description

[Technical Field]

[0001] The present invention relates to a liquid level meter that reflects the liquid level in a tank to the outer surface using a magnet. Summary of the Invention [Problem to be solved by the invention]

[0002] A liquid level gauge for a non-transparent tank that directly reflects the liquid level inside to the outside.

[0003] A float with a magnet is placed on the surface of the tank liquid, and a tube filled with water and a float with a magnet inside, with a specific gravity of nearly 1, are placed on the outside, and they move in tandem.

[0004] The liquid volume is reflected directly on the outside, making it easy to see. DETAILED DESCRIPTION OF THE INVENTION

[0005] A magnetic float is placed inside the tank, and an indicator that moves with the float is placed on the outside of the tank in the manner described below to indicate the liquid level.

[0006] The mechanism is simple, but measures are needed to prevent the inner and outer magnets from separating. Possible solutions include using a strong magnet, using multiple magnets, using a stick to move them together if they can be moved from above, connecting a string to the top and moving it, or building a fence around the magnets.

[0007] The inner magnet can be a lightweight float like a ping-pong ball (of appropriate size) with many disk-like magnets attached to its surface. It can also be a string of several of these, or a Styrofoam disk with magnets attached around it.

[0008] The outer magnetic indicator can be adjusted to a specific gravity of 1 and filled with water, which can be moved up and down, or a balloon (helium, vertical) can be attached to make the entire tube have the same specific gravity as air, which can be used to move the wall up and down. It is easier to attach string or fences to the wall than to the inside.

[0009] It is also possible to use a large number of granular magnets on the outer surface. Density is not a consideration.

Claims

1. A device that reflects the tank liquid volume to the outside using the force of internal and external magnets.

2. Among the contents described in claim 1 above, a balloon is attached to a magnet on the outer wall and floats.

3. Among the contents of claim 1, granular magnets are used for the magnets on the outer wall.
