Rotating Level Indicators

 Rotating Level Indicators type LIS are installed normally on the silo to indicate the max. & min. material levels. They are designed to signal the presence of material in silos, hoppers, etc., commonly used for material having a density ranging from 0.5 to 2 t/m2. Multi level indicators are also used to show more level points. It is very easy to install it from outside of the silo with the accessory (threaded pipe) .
