Description: Float level is a simple structure, easy to use level control devices, it does not provide power, no complicated circuit, it has a smaller volume than the general mechanical long working life and other advantages. As long as the material selection is correct in shape, and the nature of any liquid or pressure, temperature can be used, which in the shipbuilding industry, generating equipment, petrochemical, food industry, water equipment, dyeing and finishing industry, hydraulic machinery, etc. have been widely applications. How it works: An important level magnetic reed and the float composed of magnetic material inside the float, set up one or more magnetic reed in a closed non-magnetic metal pipe or plastic pipe, and then the catheter through a or more with magnetic float, and double loop control with fixed float and reed in the relevant position, the float rises or falls with the liquid, use inside the ball close to the beginning of the reed contact, resulting in open and closed action, for level control or direction (when float near the reed is turned on; off when you leave).
