Abstract
A device for measuring the mass rate of flow which operates according to the Coriolis principle, with a measurement tube (1) and a magnet coil (7) of a bobbin (9) and a winding (10) attached to it for exciting and/or detecting vibrations of the measurement tube (1). The bobbin (9) of the magnet coil (7) has a specific thermal conductivity of at least 1 W/(K m). This enables the heat which forms in the magnet coil (7) to be efficiently dissipated to the surrounding vicinity without cooling elements, such as cooling fins, being necessary. In this way, the efficiency of the device for measuring the mass rate of flow using the Coriolis principle is altogether improved.
