Method of, and apparatus for, measuring the true contents of a cylinder of gas under pressure |
| abstract |
There is provided a sensor assembly (200) for measuring physical properties of a gas under pressure within a pressure vessel (100). The sensor assembly (200) comprises a housing and a piezoelectric oscillator (202) for immersion in the gas within the pressure vessel (100). The sensor assembly (200) is arranged, when immersed in said gas, to measure the density of the gas within the pressure vessel (100). The housing comprises a first chamber and a second chamber. The first chamber is in fluid communication with the second chamber and substantially encloses said piezoelectric oscillator. The second chamber is in fluid communication with the interior of the pressure vessel. By providing such an arrangement, the true contents (i.e. mass) of fluid in a pressure vessel such as a cylinder can be measured directly and accurately. The housing of the present invention alleviates noise and errors generated by convective currents within a gas cylinder 100, enabling an accurate determination of mass, or rate of change of mass. through direct derivation from the density of the gas in the cylinder. |
