Abstract

A sensor of a thermal flow measuring device, as well as the flow measuring device itself. The sensor comprises a sensor platform, which bears at least one measuring sensor element and a heated sensor element. Each of the at least two sensor elements is surrounded by a metal sleeve, which protrudes from the sensor platform. The sensor has a plate-shaped element, which defines a plane, whose axis extends parallel to the axis of at least one of the metal sleeves, wherein the plane is spaced from the sensor platform in the axial direction of the metal sleeve. The metal sleeve with the heated sensor element has a terminal end face and the plate-shaped element is provided along the end face of the metal sleeve with the heated sensor element for flow guidance.
