| 发明名称 | Pressure measuring device | ||
| 摘要 | A pressure measurement device for enabling non-intrusive pressure measurement of a first fluid present in a volume having at least one wall is provided. The device includes an enclosed space filled with a second fluid, a transmitter provided in the enclosed space and adapted to transmit a standing wave in a direction of the wall, means for varying a pressure of the second fluid in the enclosed space, a detector for measuring data related to a resonance of the wall and a processor for determining a characteristic change in the data. | ||
