FILL LEVEL GAUGE FOR MOISTURE DETERMINATION

摘要

Described is a method and system for a level measurement. An echo curve is analyzed, and both the level and the moisture content of the stored material is determined therefrom. The level measuring instrument works in such an energy-saving manner that it is sufficient to supply the instrument with power using a 4 . . . 20 mA two-wire conductor loop that is also used to transmit at least some of the measured values.
