Abstract

Presented is a measuring device for recording a gas mass flow of an internal combustion engine. The measuring device includes a sensor element for recording the gas mass flow. The sensor element includes an evaluation circuit connected downstream of the sensor element. The evaluation circuit includes an adder for determining a total mass flow over a multiplicity of engine cycles.
