Product Information

Effortless Material Level Monitoring: The 4B Auto-Set Level Indicator is a radio-frequency level indicator that detects low, medium and high levels on almost all liquids and granular solids, such as powders, grains and sugar.

The unit has been designed to effortlessly automate the process of monitoring material levels stored in tanks, bins, silos or other containers.

Improve overall efficiency by maintaining material output, reduce stoppage time due to lack of material and prevent overflow.
