ABSTRACT:
A length of conduit is coupled at its ends to a heat sink. A pair of thermocouples are joined to the conduit at spaced points intermediate the ends of the conduit. A closed loop of heat conductive material contacts the conduit midway between the thermocouples. The conductive material is heated, and heat is conducted to the conduit. The thermocouples produce outputs representative of the flow of fluid through the conduit.
