    • A heat transmission measuring instrument, namely a flow monitor for electric detection of heat losses in a flowing medium has a metal, circular-cylindrical measuring instrument housing (1) provided with an external thread (2), having a first temperature measuring element (3), having at least one heating element (4) and having a second temperature measuring element (5), wherein the first temperature measuring element (3), at least one heating element (4) and the second temperature measuring element (5) are applied to one side of a substrate foil (6) that is a good electrical insulator and a good thermal conductor, and the substrate foil (6) is put into thermally conductive contact with the measuring instrument housing (1) with its side remote from the temperature measuring elements (3, 5) and the heating element (4), at least in the regions in which the temperature measuring elements (3, 5) and the heating element (4) are applied. The manufacture of the flow monitor shown is simplified by providing that a plastic holder (11) adapted to the inside diameter of the measuring instrument housing (1) is provided, and the substrate foil (6) is disposed between the plastic holder (11) and the measuring instrument housing (1).
