| Summary: | This paper addresses the development of flow sensors optimized for heating,
ventilating, and air conditioning systems. The sensors are based on the
printed circuit board technology facilitating robust, flexible (in terms of
layout), and cost-effective devices. Two approaches for measuring fluid
quantities like flow velocity over the whole cross section are investigated
in this context. The first one relies on hot-film transduction and stands out
for its simplicity, but also shows some severe limitations, which can be
circumvented by the second approach based on calorimetric transduction.
Supported by extensive numerical simulations, several sensor embodiments were
investigated and fabricated. After experimental characterization, measurement
and simulation results were compared, which turned out to be in good
agreement. |
