L312B Series
Small remote float chamber level switch
The L312B Remote Chamber Level Switch is a compact, level monitoring device designed for installations where internal tank mounting is impractical or impossible. Encased in its own metal float chamber, the L312B can be mounted on the exterior of a tank and supported through pipe connections. The switch and float mechanism are easily detached from their chamber for cleaning and maintenance procedures. Material options include brass or stainless steel mounts paired with a buna or stainless steel internal float.
Technology
Float level switches
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.
