The LevALERT Indicator from LTJ Enterprises is a mechanically operated instrument that senses the weight of the granular material, rotating a color tube located within the Indicator from a black “off” color to a brilliant yellow “on” color. And, as the granular material recedes, the LevALERT automatically resets back to the black color. No electrical power is needed to operate. The LevALERT Indicator can sense most any granular bulk solids ranging from pellets to powders that weigh between 10-100 pounds/cubic foot.

The LevALERT Indicator can be installed anywhere along a vertical wall section at critical “key” levels important to the user, such as an upper level to alert the user when the bin is full or at lower level to alert the user when the bin is empty.
