A magnetic Level Gauge is also called a magnetic level indicator. Magnetic Level Gauge is developed based on the principle of buoyancy and magnetic effect. The magnetic float in the measuring cylinder drives the two-color turning column on the external display of the measuring cylinder to flip with the increase (decrease) of the liquid level to be measured. As the position of the float changes, the indicator moves up and down the same amount. Supports top-mounted and side-mounted. It can be used for liquid level detection in high temperature, low temperature, high pressure, strong corrosion, highly toxic and dangerous environments.
