Abstract
A heat transfer indicating device for monitoring and/or measuring a flowing medium, especially a flow indicator and/or a flowmeter, with a preferably flexible component carrier (1), with electrical and/or electronic components (2) on the component carrier (1) and connected to one another to form a circuit, with a heating element (3), with temperature measuring element (4), with electrical connection (5) and with a housing. The flow indicator can be produced with relatively low cost, is relatively simple to mount, and can be easily re-opened again so that it can be repaired in case of a defect and the parts not affected by the defect can be re-used, by the fact that component carrier (1) is formed of two component carrier halves (1a, 1b) located on top of one another and between which the heating element (3) and temperature measuring element (4) are located.
