This paper addresses the development of a flow sensor optimized for heating ventilating and air conditioning systems. The sensor is based on the printed circuit board technology facilitating robust, flexible (in design layout), and cost-effective devices. Two approaches for measuring fluid quantities like flow velocity and flow rate are investigated in this context. The first one relying on hot-film transduction shows severe limitations while the second one based on calorimetric transduction is able to overcome these drawbacks. Guided by extensive computer numerical simulations, two sensor embodiments were investigated, optimized, and fabricated. Afterwards, the sample devices are characterized by measurements and compared to simulation results which both turned out to be in good agreement.
