Method of regulation of the water level in boilers or steam generators, in which the inlet flow of feedwater is regulated in response to a deviation signal proportional to the difference between the real measured water level and a reference level, the proportionality factor being a linear function of the power level of the boiler with respect to the nominal power, modified by a non-linear function of xi which preserves very low values for xi close to zero and increases very rapidly for higher values of xi so that the total gain is increased for low power levels and high values of xi within a restricted range.
