Product Description

Float level switches are suitable for liquid level control when the measured liquid level in the liquid storage equipment and storage & transportation tools in industries such as chemical, petroleum, and ship industries reaches a given point.

Principles
Such switches enable the contact switch to work based on the leverage principle and magnetic action, thus controlling the liquid level in situations that require frequent operation at the liquid level positions
