<p>The measuring arrangement (1) has a heating device (3) for introducing heat (W) into the fluid (F) flowing through the line. The heating device is placed at an outer wall (2B) of the line. A temperature measuring device (4) is provided for detecting a surface temperature of the line. The heating device has a temporary constant heating capacity and registers a constant heat quantity per unit of time. Independent claims are also included for the following: (1) an air separation unit has a line that conveys the bottom liquid that has oxygen, krypton, xenon, hydrocarbons, carbon dioxide and nitrogen oxides; and (2) a method for detecting a fluid flow in a line.</p> |
