Beschreibung
Zusammenfassung:	A level indicator for blood reservoirs, in particular of medical apparatus, having a level-responsive component to be provided on the wall of the blood reservoir is provided with an oscillator set to an operating frequency of greater than or equal to 50 MHz and having integrated into its circuit the level-responsive component which, when a preset limiting value is passed, changes the phase condition or amplitude condition decisive for the oscillation of the oscillator.
