Thermal flow sensor for determining a flow rate of a fluid

Abstract

The invention relates to a thermal flow sensor (2) for determining a flow rate of a fluid (1), comprising: a sensor body (11) with a flow section (12), through which fluid flows (3) in a flow direction during use, a flow sensor configuration (13), comprising multiple flow sensing elements (14), such as two or three, arranged at multiple locations in the flow section for measuring the flow velocity at different locations in the flow section, wherein the multiple flow sensing elements (14) are arranged parallel to each other in a plane parallel to the flow section, and wherein single flow sensing elements (14) of the multiple flow sensing elements (14) can be read out.
