Abstract
(DE)
Die Erfindung hat einen Wärmemengenzähler (1) für ein Medium (M) zum Gegenstand, welcher einen Leitungsabschnitt (2), eine Prozessoreinheit (3) und einen in einem Innenraum (2a) des Leitungsabschnitts (2) angeordneten Sensor (4) umfasst, wobei mittels des Sensors (4) eine Temperatur des Mediums (M) und eine Strömungsgeschwindigkeit, mit welcher das Medium (M) den Leitungsabschnitt (2) durchströmt, messbar ist. Hierbei ist der Sensor (4) als CTA-Sensor (5) ausgebildet ist, welcher einen in dem Leitungsabschnitt (2) von dem Medium (M) umströmten Messwiderstand (6) umfasst, und hierbei umfasst der Wärmemengenzähler (1) eine Energieversorgungseinrichtung (7), an welche der Messwiderstand (6) derart angeschlossen ist, dass der Messwiderstand (6) in einem Aufheizbetrieb von der Energieversorgungseinrichtung (7) versorgt ist.
(EN)
The invention relates to a heat meter (1) for a medium (M), which heat meter comprises a conduit portion (2), a processor unit (3), and a sensor (4) arranged in the interior (2a) of the conduit portion (2), wherein a temperature of the medium (M) and a flow rate at which the medium (M) flows through the conduit portion (2) can be measured by means of the sensor (4). The sensor (4) is designed as a CTA sensor (5) which comprises a measuring resistor (6) around which the medium (M) flows in the conduit portion (2), and the heat meter (1) comprises an energy supply device (7) to which the measuring resistor (6) is connected in such way that in a heating mode, the measuring resistor (6) is supplied by the energy supply device (7).
