Abstract
Disclosed is an apparatus for determining a flow of a medium through a pipe, as well as a method for operating the apparatus. The apparatus comprises a heating element at least partially in thermal contact with the medium and which is heatable by means of a heating signal, and a first temperature sensor for registering a temperature of at least one component of the apparatus or the temperature of the medium. The heating element and the first temperature sensor are arranged outside of the pipe. The apparatus includes at least one coupling element, which is at least partially in thermal contact with the heating element, the first temperature sensor and/or a portion of the pipe or tube and serves to assure a thermal coupling between the heating element and the first temperature sensor and between the heating element and the medium.
