Just look for the BLACK DIAMOND.

Why LevALERT® Indicator?

Create Safety & Efficiency

Why Climb? Monitoring bin levels has never been this fast and easy! In just one glance, you can instantly see if the granular material in your bin is above or below the level of the LevALERT® Indicator, all while keeping both feet safely on the ground. Climbing bin ladders not only is time consuming but dangerous for both you and your employees.

Just look for the large black diamond and if the granular material is at or above the level of the LevALERT it will show a bright Yellow color. If the material is below the LevALERT it will show a black color. Simple, fast and easy!

The yellow color in the Indicator is made using a 3M brand lemon yellow reflective film that is highly visible from well over 300 feet during daytime. And at night, simply use a flashlight and the reflective yellow shines bright!


The Mechanics Are Simple

The LevALERT® Indicator 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 needed to operate.

The LevALERT® Indicator can sense most any granular bulk solids ranging from pellets to powders that weigh between 10 to 100 lbs./cubic foot (160 to 1,600 kg./cubic meter).

Typical uses include:

  • Agricultural Grains and Feeds
  • Pellets
  • Fertilizers
  • Granular Chemicals
  • Minerals
  • Powders
  • Sand

. . . to name a few. Just about anything you'd store in a bin.


Determine Key Levels

You can install the LevALERT® Indicator anywhere along a vertical wall section at critical “Key” levels important to you. Such as an upper level to alert you when the bin is full or at low level to alert you that the bin is empty.

HINT: Many times it is more important to know a certain level in advance of full or empty, such as a "1 truckload before full" level to create lead time for your next move. Or for lower levels the “2 days left of feed” level giving you advance warning before you run out.

On bins that are filled and empied more frequently, consider installing multiple LevALERT units at mid point levels. LevALERT® Indicator is an affordable way to keep in constant touch with your inventory.


Need to perform an electrical function?

Expand the Indicator’s capabilities by performing an electrical operation as well as the mechanical “visual” indication. Simply add this optional Micro-Switch to the LevALERT® Indicator to turn off or on motors, lights, sound horns or to notify your other electrical devices.

This switch is a sub-miniature basic switch which is hermitically sealed so it is not affected by neither moisture or dust making it an ideal choice in harsh outdoor conditions. Contains both NO (normally open) and NC (normally closed) circuitry in both AC and DC voltage.

Micro Switch part number 10100
