| 141 | Method and Device for Determining the Filling Mass of a Cryogenically Stored Gas in a Container | US14834706 | 2015-08-25 | US20150362353A1 | 2015-12-17 | Markus KAMPITSCH; Stefan Schott |
| A method for determining a filling mass in a thermally insulated container for a cryogenically stored gas is disclosed. The filling mass is determined by way of a known container volume and a calculated density of the gas content of the container. A temperature sensor is used for measuring a mixing temperature of a liquid and a gaseous phase of the gas. The liquid phase is extracted by way of a first extraction supply line at the geodetically lowest point, and the gaseous phase is extracted by way of a second extraction supply line at the geodetically highest point of the container cavity. Downstream of the extraction points, after a convergence of the first and the second extraction supply line to a single extraction supply line leading out of the container, the temperature sensor is placed where a complete and thorough mixing of the liquid and the gaseous phase of the gas from the first and second extraction supply line has already taken place. | ||||||
