In the method to determine wether a preset limit value, expressed as a percentage of a liquid portion contained in a liquid mixture and having an evaporation temperature lower than that of the remaining liquid, has been reached or exceeded, a spontaneous and measured change of an electric resistance wire immersed in the liquid mixture and temporarily supplied with a predetermined power amount is used; the resulting heating of the wire, reaching or exceeding the boiling temperature of the liquid mixture is used to determine appropriate measured magnitudes. By inputting a set power quantity determined during a representative test, in order to heat the wire to the boiling temperature of the liquid mixture, either the power conversion of power obtained during a given constant time lapse for power supply is measured, or, for a predetermined power quantity, the time lapse required for a power conversion is measured; said data are then compared with the corresponding measured magnitudes determined during the test. |
