DEVICE FOR DETERMINING THE FILLING LEVEL OF A FLUID

摘要

A device for determining the filling level of a fluid in a container, in particular in the oil reservoir of a vehicle, is provided. The device has at least one sensor element, at least one control unit, at least one energy source, and at least one transmitting unit for wireless transmission of measured data. The at least one energy source is a thermal generator, in particular a thermocouple. The device has at least one energy storage device. The thermal generator is configured for measuring a time-dependent temperature gradient, the thermal generator has a signal-conducting connection to the control unit, and the control unit is configured for placing the device from an energy-saving state into a ready-to-measure state. A method for determining the filling level of a fluid in a container using the device, and a vehicle with the device, in particular a motor vehicle, are also provided.
