用于确定流体的填充水平的装置
摘要：
本发明涉及一种用于确定流体的填充水平的装置，尤其用于确定流体在容器、尤其机动车的油箱中的填充水平，其中，该装置构造为容器的封闭件并且具有至少一个传感器元件和至少一个控制装置，根据本发明，该装置具有至少一个能量源和用于无线地传输测量数据的至少一个发射装置，至少一个能量源是热发生器、尤其热元件，该装置具有至少一个能量储存装置，热发生器构造用于测量时间上的温度梯度，热发生器具有至控制装置的传导信号的连接并且控制装置构造用于将该装置置入节省能量的状态中和准备好测量的状态中。
摘要（英）：

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.
