Magnetrol® side-mounting float switches mount horizontally to any tank or vessel through a threaded or flanged pipe connection. Standard models are normally equipped with a single switch mechanism for high or low level alarm or control applications. Tandem models, with two switch mechanisms, are available for two-stage applications.
All float operated liquid level controls operate on the basic buoyancy principle which states “the buoyancy force action on an object is equal to the mass of liquid displaced by the object.” As a result, floats ride on the liquid surface partially submerged and move the same distance the liquid level moves. Because of this, they are normally used for narrow level differential applications such as high level alarm or low level alarm.
Options
Side mounted units employ permanent magnetic force as the only link between the float and the switching element. As the pivoted float follows liquid level changes, it moves a magnetic sleeve into or out of the field of a switch actuating magnet causing switch operation. A non-magnetic barrier tube effectively isolates the switch mechanism from the controlled liquid.
