Abstract
A flow sensor of the thermal type having a U-shaped sensor tube with two legs and a connecting limb with two adjoining electrical resistance elements, and with a housing. The sensor tube has an inlet side and an outlet side. The housing has a first and a second housing part of a thermally well-conducting material, each with an inner surface provided with cavities and with an outer surface. The housing parts are placed with their inner surfaces against each other, while the U-shaped sensor tube has a main surface that extends parallel to the inner surfaces. The housing parts surround the connecting limb and the legs of the U-shaped sensor tube such that the sensor tube is thermally clamped in between the housing parts in two locations: a first location situated between its inlet side and the upstream resistance element, and a second location situated between its outlet side and the downstream resistance element.
