Measuring device

A measuring device for measuring flow velocity or volume flow or density of a medium flowing through at least one measuring tube, comprising:

• the at least one measuring tube for conveying the medium;
• a measuring transducer adapted to register at least one measured variable and to output at least a first measured value representing the measured variable;
• at least one temperature sensor adapted to register a temperature of the measuring tube;
• an electronic measuring/operating circuit configured to operate the measuring transducer and the temperature sensor and provide flow or density measurement values;
• wherein the temperature sensor has a sensor element and at least two electrically conductive leads for electrical connection of the sensor element with the electronic measuring/operating circuit,
• wherein each lead is connected with the sensor element in the region of a connection location of the sensor element;
• wherein each lead has a first section following on the connection location, wherein the sensor element has a maximum periphery;
• wherein 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;
• wherein the leads are guided in their first section at least in certain regions along the maximum periphery;
• wherein the leads in their first section are at least in certain regions in thermal contact with the measuring tube.
