Level Indicators

           
 

4B has a wide range of radio frequency (RF), rotary paddle and capacitance point level indicators for detecting high, intermediate, or low levels of liquids, powders and free flowing granular solids stored in tanks, bins, silos or other containers. Certain units can also be used as plug or choke detectors in chutes, conveyors and elevator legs.
