Abstract

Zur Bestimmung insbesondere des Durchflusses eines Mediums durch ein Rohr sieht die Erfindung ein Verfahren zum Messen des Durchflusses mindestens eines Mediums durch ein Rohr vor, wobei innerhalb zumindest eines Teilvolumens des Mediums ein Erhitzen erfolgt, eine Temperatur an mindestens einer Stelle stromab der Wärmungsstelle gemessen wird und anschliessend eine Messgrösse des Mediumstroms bestimmt wird, das dadurch gekennzeichnet ist, dass das Erhitzen und das Messen der Fluid-Temperatur berührungslos erfolgen. Weiterhin sieht die Erfindung eine Vorrichtung zum Messen des Durchflusses mindestens eines Mediums durch ein Rohr, mit einer Heizeinrichtung zum Erhitzen im Medium und wenigstens einer ersten Temperatureinrichtung zur Bestimmung einer Temperatur des Mediums und Auswertemittel zur Bestimmung einer Messgrösse des Mediumstroms aufgrund des Messsignals der Temperaturmesseinrichtung vor, bei der die Heizeinrichtung zum berührungslosen Erhitzen und die erste Temperaturmesseinrichtung zum berührungslosen Messen der Temperatur im Medium ausgebildet ist.
