L250AD Series
Integral dispensing tube level switches
The L250AD is a combination single or dual-point level switch and integral dispensing tube designed for use in the pharmaceutical industry. The unit has the capability of dispensing liquids as well as monitoring their levels of critical laboratory solutions from within a plastic-lined container. Its spring-loaded mount adjusts the sensor for optimum submergence and its ultra low-level float requires only 3/16″ of liquid to operate. Options include the choice of a polysulfone/polypropylene or stainless steel construction with a variety of switch types.
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.
