Abstract
A thermal mass flow meter is disclosed for determining a material flow through a vessel. In this case, a sensor arrangement is mounted on a holder immersed into a vessel with a flowing medium. It is proposed that the sensor arrangement comprises a first and a second measuring element, with one of the respective measuring elements being heated while the other respective measuring element is not heated and that the two measuring elements can be heated alternately.
