Abstract

The device comprises a measuring element (8) with means for mounting it securely in the container measuring instrument is affected by the substance when it is filled up to the level of the instrument. There is an oscillator (2) which is connected with this instrument (8), which delivers a signal when the substance fills the container up to the level of the instrument (8). A circuit is connected to the oscillator n2), which responds to its signal and indicates when the substance has reached the instrument level. The substance filling the vessel or tank may be either a liquid or a free flowing solid granular material.
