Abstract: A measuring device for measuring flow velocity includes a measuring tube, a measuring transducer for registering a measured variable and outputting a first measured value representing the measured variable, a temperature sensor, and an electronic measuring/operating circuit. The temperature sensor has a sensor element and electrically conductive leads. Each lead is connected with the sensor element and has a first section following on the connection location. The sensor element has a maximum periphery. The first section has a separation of less than 5% of a measuring tube radius from a measuring tube wall, wherein a length of each lead in the first section is at least 25% of the maximum periphery. The leads are guided in their first section at least in certain regions along the maximum periphery, and in their first section are in certain regions in thermal contact with the measuring tube.
