Magnetic flip level gauge is a liquid level measurement instrument based on the principle of magnetic coupling. It uses a float to drive an external magnetic flip plate to flip with the liquid level, and displays the liquid level height intuitively through a red and white dual color interface. Its main body is isolated from the medium, with no risk of leakage, and supports complex working conditions such as high temperature and high pressure, strong corrosion, and explosion prevention. It can be equipped with a signal output module for remote monitoring. Simple structure, maintenance free, widely used in fields such as chemical engineering, energy, water treatment, etc.
