Vertical liquid level sensors can be mounted either at the top or bottom of a tank/vessel and feature a stem and a float. The stem is stationary and attaches to the tank with one or more reed switches hermetically sealed inside. The float is a doughnut-shaped object placed around the stem that rises and falls with the level of the liquid. When the level of the float aligns with the level of the reed switch inside the stem, it magnetically actuates the reed switch sending an electrical signal through the wires to the outside of the tank.
