Description

A long-range level gauge for high and low pressure vessels Technical Field

[0001] This utility model relates to a long-range level gauge for high and low pressure containers, comprising high and low pressure containers, a magnetic float, a high-pressure resistant connecting pipe, a magnetic switch array, and a light-emitting diode array. The connection method is as follows: the liquid level in the high and low pressure containers is controlled by the high-pressure resistant connecting pipe, causing the magnetic float to float. The magnetic induction of the magnetic float activates the magnetic switch at the corresponding position, illuminating the light-emitting diode connected to the magnetic switch. This utility model determines the liquid level by observing the position of the illuminated light-emitting diode from a distance. It has a simple structure, reliable operation, and is particularly suitable for medium and large containers and high-risk environments where close-range liquid level observation is not possible. It belongs to the field of measuring instrument manufacturing and application. Background Technology

[0002] Application number 03279494.0 discloses a high-pressure magnetic levitation level gauge, in which the level display is determined by a series of flip-up bicolor spheres, i.e., the liquid level is determined by the change in color of the spheres at the liquid level. However, because the colors of the spheres are not easily distinguishable at long distances, this can easily lead to misreading of the liquid level. Summary of the Invention

[0003] To address the shortcomings and defects of existing technologies, a long-range liquid level gauge for high and low pressure containers has been invented. It comprises high and low pressure containers, a magnetic float, a high-pressure resistant connecting pipe, a magnetically sensitive switch array, and a light-emitting diode array. The key feature is that one end of the magnetically sensitive switch array is connected to the positive terminal of a power supply, and the other end is connected to the positive terminal of the light-emitting diode array. The negative terminal of the light-emitting diode array is connected to the negative terminal of the power supply. The connection method is as follows: the liquid level in the high and low pressure containers floats the magnetic float on the liquid surface within the high-pressure resistant connecting pipe. The magnetic induction of the magnetic float causes the magnetically sensitive switch on the outside of the high-pressure resistant connecting pipe, corresponding to the liquid level position, to activate, illuminating the light-emitting diode connected to the magnetically sensitive switch.

[0004] This utility model relates to a long-range liquid level gauge for high and low pressure containers. Its significant innovation and technological advancement lies in determining the liquid level by observing the position of the lit LEDs from a distance. It has a simple structure, reliable operation, and is applicable to both high and low pressure containers. It is particularly suitable for medium and large containers and high-risk environments where the liquid level cannot be observed at close range. The high-pressure connecting pipe can be adapted to the pressure requirements of different containers by changing the pipe diameter, wall thickness, and material. The LEDs in the LED array can be selected according to the distance of the observed liquid level, including their light emission color, light emission power, light emission brightness, and diameter. Attached Figure Description

[0005] Figure 1 is a schematic diagram of the composition and connection method of this utility model. Detailed Implementation

[0006] As shown in Figure 1, this utility model is achieved through the following technical solution. A long-range liquid level gauge for high and low pressure containers comprises a high and low pressure container 1, a magnetic float 2, a high-pressure resistant connecting pipe 3, a magnetic sensitive switch array 4, and a light-emitting diode array 6, etc., characterized in that: one end of the magnetic sensitive switch array 4 is connected to the positive terminal of a power supply, and the other end is connected to the positive terminal of the light-emitting diode array 6. The negative terminal of the light-emitting diode array 6 is connected to the negative terminal of the power supply. The connection method is as follows: the liquid level in the high and low pressure container 1 floats the magnetic float 2 on the liquid surface inside the high-pressure resistant connecting pipe 3 through the high-pressure resistant connecting pipe 3. The magnetic induction of the magnetic float 2 causes the magnetic sensitive switch 4-1 on the outside of the high-pressure resistant connecting pipe 3 at the position corresponding to the liquid level to be turned on, lighting up the light-emitting diode 6-1 connected to the magnetic sensitive switch 4-1.

[0007] Furthermore, the high-pressure resistant connecting pipe 3 can be adapted to the pressure requirements of different containers by changing the pipe diameter, wall thickness and material.

[0008] Furthermore, the high-pressure resistant connecting pipe 3 is made of a non-magnetic material, such as 304 stainless steel.

[0009] Furthermore, the magnetic switch array 4 can be composed of reed switches or other magnetic switches.

[0010] Furthermore, the LEDs in the LED array 6 can have their emission color, emission power, emission brightness, and diameter selected based on the distance of the observed liquid level.
