Abstract

A determining device for determining at least one component of a liquid, e.g., a fuel mixture, for use in motor vehicles, includes at least one sensor which has at least one connecting device for coupling microwave signals into the liquid and/or out of the liquid. The determining device is implemented as a hand-held measuring instrument.

First claim

What is claimed is:

1. A determining device for determining at least one component of a liquid, comprising:
at least one sensor determining the at least one component, wherein the sensor has at least one connecting device for coupling microwave signals at least one of into the liquid or out of the liquid;
wherein the determining device is configured as a hand-held measuring instrument,
wherein the sensor includes:
at least one sensor head, and
at least one flow-pipe section through which the liquid flows, the at least one flow-pipe section extending at least essentially transversely to an axis of the at least one connecting device,
wherein the sensor head includes at least one admission device for admitting the liquid to the sensor, wherein the at least one admission device is of one of a funnel device and an adapter for connection of a quick hose connector, wherein the at least one admission device is disposed at an end of the at least one flow-pipe section.

2. The device as recited in claim 1 , further comprising:
at least one of an indicating unit or an operating unit detachably connected to the sensor and configured to display at least one of (i) the at least one component or (ii) a fault condition.

3. The device as recited in claim 2 , wherein the at least one of the indicating unit or the operating unit includes at least one display.

4. The device as recited in claim 3 , wherein the at least one of the indicating unit or the operating unit includes at least one microcontroller.

5. The device as recited in claim 4 , wherein the sensor has at least one housing which accommodates at least one measuring area into which the liquid is introduced, and wherein the connecting device is disposed at least partially in the measuring area.

6. The device as recited in claim 1 , wherein the sensor is one of a biodiesel-fuel sensor, a urea/water solution sensor, an alcohol solution sensor, and an antifreeze/coolant sensor.

7. The device as recited in claim 1 , wherein the determining device is configured as a built-in unit for a blender pump.
