The principle of flip level gauge:

The magnetic flap level gauge (also known as the magnetic float level gauge) is developed based on the principle of buoyancy and magnetic coupling. When the liquid level in the tested container rises or falls, the magnetic float in the liquid level gauge body tube also rises or falls accordingly.

The permanent magnetic steel inside the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flip columns to flip 180 °. When the liquid level rises, the flip column changes from white to red, and when the liquid level drops, it changes from red to white. The red white boundary of the indicator is the actual height of the liquid level inside the container, thus achieving clear indication of the liquid level.

Additional Information:

Magnetic flap level gauges are widely used for liquid level measurement and control in the production processes of industries such as power, petroleum, chemical, metallurgy, environmental protection, shipbuilding, construction, and food.

1. Structure of magnetic flap level gauge

According to the principle of buoyancy, the float in the measuring tube moves up and down with the rise and fall of the liquid level. The permanent magnetic steel inside the float drives the red and white flip columns to flip 180 degrees through magnetic coupling. When the liquid level rises, the flip column changes from white to red, and when it falls, it changes from red to white, thus achieving the indication of the liquid level.

2. Upper and lower limit switch output

By using a magnetic float to move with the liquid level, the reed switch installed at the set position of the liquid level gauge riser is activated to achieve on-off control or alarm.

3. Electric remote transmission of liquid level gauge

Install a transmitter on the magnetic flap level gauge. The transmitter consists of two parts: a sensor and a converter. It moves up and down through a magnetic float and uses magnetic coupling to sequentially move the measuring elements inside the conduit, obtaining changes in resistance signals and converting them into standard current signals of 0-10 or 4-20mA for output. These signals are then connected to digital display instruments or computers for remote display and control.
