The core principle of a magnetic sensitive dual color liquid level gauge is to utilize the magnetic field interaction between the magnetic steel inside the float and the magnetic components (such as flip plates or magnetic columns) in the external indicator to achieve visual indication of the liquid level. The specific process is as follows:

1. Float changes with liquid level: The float is equipped with magnetic steel inside, and when the liquid level rises or falls, the float moves up and down accordingly.

2. Magnetic field driving indicator: The magnetic field of the float is transmitted to the external indicator mechanism through magnetic conductive materials (such as stainless steel flippers or magnetic columns), driving the flipper to flip or the magnetic column to change color.

3. Dual color display: Usually two colors (such as red and white) are used to distinguish the liquid and gas phases. For example, red represents the presence of liquid phase, while white represents the absence of liquid phase, forming a clear liquid level interface.

The core structure of magnetic sensitive dual color liquid level gauge:

1. Float system

The float is embedded with magnetic steel, with a density lower than the measured liquid, and can float with the liquid level.

The float material is usually stainless steel or corrosion-resistant material, suitable for different media.

2. Instructing institutions

Flip plate: composed of multiple magnetic flip plates, the flip plate flips when the liquid level changes, presenting a dual color interface.

Magnetic column: Using a magnetic level gauge column, the liquid level is indicated by the color change of the magnetic column.

Magnetic component: Connect the float and indicator mechanism to transmit magnetic field signals.

Shell and seal: The main body is made of stainless steel or plastic material, filled with inert gas or sealed inside to prevent medium leakage.

The main features of the magnetic sensitive dual color liquid level gauge are:

1. Strong visualization

The dual color display is intuitive and clear, allowing for remote observation of liquid levels and suitable for on-site monitoring.

2. High reliability

No mechanical friction components, long lifespan, and low maintenance costs.

The principle of magnetic coupling avoids the risk of leakage and is suitable for flammable and explosive environments.

3. Wide adaptability

It can measure various liquids (such as water, oil, chemical solutions, etc.), with a temperature resistance range usually from -40 ℃ to+250 ℃.

Suitable for high-pressure, high vacuum, or corrosive media environments.

4. Flexible installation

It can be installed horizontally, vertically, or diagonally, and supports various methods such as top installation and side installation.
