Abstract

The invention relates to a thermopile-based flow sensing device. Example systems, apparatuses, and methods are disclosed sensing a flow of fluid using a thermopile-based flow sensing device. An example apparatus includes a flow sensing device comprising a heating structure having a centerline. The flow sensing device may further comprise a thermopile. At least a portion of the thermopile may be disposed over the heating structure. The thermopile may comprise a first thermocouple having a first thermocouple junction disposed upstream of the centerline of the heating structure. The thermopile may further comprise a second thermocouple having a second thermocouple junction disposed downstream of the centerline of the heating structure.

Description

technical field [0001] Example embodiments of the present disclosure relate generally to sensors, and more particularly to flow sensors. Background technique [0002] Industrial and commercial applications are increasingly using flow sensors to measure and control the mass flow of gases and liquids. Conventional flow sensor designs typically exhibit drift characteristics that reduce their measurement sensitivity. [0003] Applicants have discovered a number of deficiencies and problems associated with conventional flow sensors. Through effort, ingenuity, and innovation, many of these identified problems have been solved by developing solutions, included in embodiments of the present disclosure, a number of examples of which are described in detail herein. Contents of the invention [0004] Disclosed herein are systems, apparatus, methods, and computer program products for providing a thermopile-based flow sensing device having low or no drift characteristics that, in som...
