level ball float

Purposes and principles DFYK Float level controller is applicable to all kinds of water tank, water tower of liquid level control, and is especially suitable for containing solid or semisolid floats in the liquid and adhesive sewage water level automatic control and alarm. When the liquid level in the lower limits, float follow reset State float on water, floating ball moving hammer out within Reed pipe and steepness of the region, Reed pipe maintains a pair of contacts disconnect, a contact closure of State. When the liquid level increases to ceiling ball float upside down, moving hammer magnetic ring Reed pipe pick-up area, close to magnetic circuit, output contact State rapid transformation (floating ball used in the mercury switch is similar to the principle of ) Description 1,Shell by charged liquid specific gravity to solid fill material, so that the total weight of the sphere is slightly smaller than the liquid the buoyancy of the ball, known as heavy. Apply liquid specific gravity range 0.65-1.5 . 2,Shell without solid fill material known as "light bulb". Used to control contains impurities, suspended solids and the level of liquid precipitation, its actions are not affected by the impact of specific gravity of liquid
