Working principle of the Magnetic level gauge

                      Working principle of the Magnetic level gauge

1. Buoyancy principle (Archimedes principle)

Because an object immersed in a static fluid will receive an upward buoyancy, the buoyancy is equal to the weight of the fluid displaced by the object. This principle is also known as Archimedes principle.

2. Connector principle

The Magnetic level gauge has a cavity (also known as the main pipe or pontoon) containing the floating ball, which forms a connector with the container through flange or other interfaces, so that the liquid level in the cavity is the same as that in the container, and the floating ball in the cavity rises and falls with the rise and fall of the liquid level.

3. Magnetic coupling

In the actual work of the Magnetic level gauge, the rise and fall of the magnetic float in the buoy can not be observed by the outside world. However, when a Magnetic level gauge indicator is installed outside the buoy, the flap will turn 180 ° due to the effect of the magnetic steel in the float on the external magnetic flap. This is because the magnetic float has an effect on the magnetic flap, which is the result of same-sex repulsion and different poles attraction. Using this principle, the outside world can clearly distinguish the actual position of the liquid level from the change of the flip color.

Because the Magnetic level gauge can work safely and reliably in various harsh environments such as low temperature, high temperature, high pressure and strong corrosion, the Magnetic level gauge is widely used in industrial production. The Magnetic level gauge is used together with the upper and lower limit magnetic switch and the dry reed remote transmitter. It can also realize the remote control, indication and recording of liquid level. It is the most ideal liquid level measuring instrument for tanks, tanks and spherical vessels.
