ABSTRACT:
The invention belongs to the field of dimensional metrology. The process according to the invention makes use of a hot wire sensor (1) passing through the free surface of the liquid. The wire is heated by a joule effect up to a temperature To. The supply to the wire is then interrupted for a predetermined time interval .tau.. The current passing through the wire at the two instants forming the bounds of this interval is determined by means of an A/D converter (3) which feeds a control and computing unit (4). From these current measurements this unit derives a value which represents the liquid level.
