Patent number: 10724882Abstract: A thermal flowmeter comprises a heating element thermally coupled to a flowing medium, a first temperature sensor and second temperature sensor. The first temperature sensor detects a flowing medium temperature in a region not affected by the heating element. The second temperature sensor detects a temperature of the heating element and also serves as a heating element. A control unit controls heating power of the heating element based on the difference between the detected temperatures at a predetermined time. The control unit provides a square wave signal to the second temperature sensor so that in a high phase it acts as heating element and in a low phase as a temperature sensor.Type: GrantFiled: November 24, 2016Date of Patent: July 28, 2020Assignee: IFM ELECTRONIC GMBHInventors: Walter Reichart, Markus Körber, Christian Kreisel, Ralf Kriesen
