<p>The flow rate of a fluid, e.g. hot water, is determined by measuring the temperature of the fluid and the cooling time between two temperature thresholds of a previously heated probe. On the basis of these values, by way of a first interpolation based on a table comprising the cooling times of the probe as a function of different temperatures and flow rates, the cooling times at the temperature measured are calculated for all the flow rates recorded on the table, then, by way of a second interpolation between the values thus calculated which are higher and lower than the value measured, the flow rate corresponding to this value is calculated.</p> |
