ABSTRACT:
A steam generator with automatic supply having a level sensor arranged in a zone of a vessel located at a set threshold level, the sensor measuring the temperature and comparing it with a reference temperature, in order to establish whether a liquid reaches the threshold level, and an adjustment means acting in relation to the steam tapping operations so that the sensor temperature varies in relation to the level of liquid over a variation range, wherein the reference temperature remains within the variation range.
