- Model 4100-LEV - Level-Ease Monitor



Continuous level monitoring of liquids and bulk solids. This unique level system provides complete flexibility for monitoring one or more tanks in one complete package. The Level-Ease 4100 sensing probe monitors the capacitance field between the probe and it’s concentric shield of the tank wall. As the level of product increases, the probe capacitance changes. This level signal is used to provide outputs, displays and relay control.
