Abstract
Various systems and methods are provided for a mass flow rate sensor. In one example, a mass flow rate sensor comprises a first signal input, a second signal input, an output for a mass flow rate signal, a first characteristic field, a second characteristic field, each of the first and second characteristic fields associating a mass flow rate value with a pair of values of a revolution rate value and an output pressure value, and a selection unit that comprises a first parameter input and a second parameter input, the selection unit configured to produce a selection signal depending on a pair of parameters respectively received via the first and second parameter inputs and to switch the mass flow rate value of either the first or the second characteristic field through to the output of the mass flow rate sensor depending on the selection signal.
