Abstract: The method involves passing the flow over a sensor element (1) with a heating arrangement (1a) for altering the temperature and a sensor element (1b) for determining its temperature. The heating arrangement is operated at least occasionally with a heating power in the form of heating pulses and a flow-dependent threshold time is measured until a defined temperature threshold is reached. AN Independent claim is also included for the following: an arrangement for implementing the inventive method.
