METHOD FOR CORRECTING OFFSET DRIFT EFFECTS OF A THERMAL MEASURING DEVICE, THERMAL MEASURING DEVICE AND GAS THROUGHFLOW MEASURING APPARATUS |
摘要 |
<p>A method for correcting offset drift effects of a thermal measurement device (10) which comprises at least one temperature sensor (15a, 15b) arranged at a defined distance from a heating device (12) for a fluid to be measured, for measuring at least one measurement variable describing the temperature and/or temperature profile during operation of the heating device (12), in which a reference measured value (35) is measured at a reference time in a first measurement of the measurement variable with the heating device (12) turned off, in which a drift measured value (36) is measured at at least one later time in a second measurement of the measurement variable with the heating device (12) turned off, and in which a drift correction is carried out during the measurement by using the heating device (12) on the basis of a difference between the drift measured value (36) and the reference measured value (35).</p> |
