Abstract:In this paper we propose a new anemometer principle. Next to the known Constant Power Anemometry (CPA) and the Constant Temperature Anemometry (CTA), here the Temperature Balanced Anemometry (TBA) is presented. A compact overview of thermal flow sensor system concepts is given. The new concept has important consequences for simple flow sensor calibration. The proposed concept is investigated using experiments on conventional thermal flow sensors. A micro flow sensor is presented in combination with an example of simple electronic interfacing circuitry.
