Magnetic Level Gauge
Working Principle
The magnetic float level gauge (also known as a magnetic float liquid level gauge) is developed based on the principles of buoyancy and magnetic coupling. When the liquid level in the measured container rises or falls, the magnetic float in the gauge's main tube also rises or falls accordingly. The permanent magnet inside the float transmits the signal to the magnetic flip indicator through magnetic coupling, driving the red and white flip columns to rotate 180°. When the liquid level rises, the flip column changes from white to red; when the liquid level falls, the flip column changes from red to white. The red-white boundary of the indicator shows the actual height of the liquid level inside the container, thus providing a clear indication of the liquid level.
Measurable and Unmeasurable Media
Media: Various liquids, including corrosive, flammable, and explosive liquids.
Magnetic float level gauges are not suitable for media containing air bubbles or suspended matter.
