Abstract
A direction-sensitive flow velocity meter in which at least first and second thermocouples of the Seebeck type are arranged in a symmetrical layout in a common semiconductor substrate. The configuration is such that imaginary lines joining the junction ends of the thermocouples each extend parallel to perpendicular flow velocity components, with the heating element or electronic circuitry for processing the thermocouple voltages being integrated into the common substrate at surface areas free of the thermocouples.
