A method of correcting measurement errors of an instrument for measuring the flow of a gas, the instrument having a selected measuring range and being constructed to produce a reading indicating the value of a gas flow in the selected measuring range, by the steps of: selecting a limited number of gas flow values which are spaced apart across the measuring range; determining the readings produced by the instrument when the instrument is measuring gas flows at the selected values; measuring the flow of the gas with the instrument to produce a reading indicating the value of the gas flow; and producing a corrected reading by calculating a function of the reading produced in the measuring step and the readings produced in the determining step.
