L180/L190 Series
Intermediate & large-size buna-n float level switches
The intermediate-sized L180 and large-sized L190 are equipped with a Buna-N float that provides optimum displacement and excellent stability in both oils and water. An optional stainless steel float is also available to accommodate aggressive environments. The two models are rated for system pressures up to 150 PSIG and temperatures up to 180 ºF. The L190, however, is best suited for highly viscous fluids.
Technology
Float level switches - Buoyancy
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.
