| 摘要 |
The present invention relates to a method for determining at least one physical variable in a positive displacement pump, wherein the positive displacement pump has a movable displacer element which delimits the metering chamber which is connected via valves to a suction and pressure line, with the result that delivery fluid can alternately be sucked into the metering chamber via the suction line and can be pressed out of the metering chamber via the pressure line as a result of an oscillating movement of the displacer element, wherein a drive is provided for the oscillating movement of the displacer element. |
