Abstract: A device for measuring the flow rate of a fluid confined by a wall member, and wherein the device comprises contacting apparatus for contacting the wall member, the contacting apparatus being formed of a material having a first heat transfer coefficient so that heat may be exchanged between the wall member and the contacting apparatus. The device further comprises heating apparatus for supplying heat to and draining heat from the contacting apparatus so that heat is being supplied to the wall member when heat is being supplied to the contacting apparatus and so that heat is being drained from the wall member when heat is being drained from the contacting apparatus. Bridging apparatus for providing thermal contact between the heating apparatus and the contacting apparatus are provided.
