| titleOfInvention | Method and apparatus for measuring molecular weight of gas |
| abstract | An instrument for measuring the molecular weight of a gas is provided, the instrument having a housing having an inlet and an interior for receiving a gas to be measured, and a high frequency planar piezoelectric crystal oscillator disposed in the housing such that the piezoelectric crystal oscillator contacts the gas when in use. And a sensor assembly configured to drive the piezoelectric crystal oscillator such that the piezoelectric crystal oscillator resonates at a single resonant frequency, measure a single resonant frequency of the piezoelectric crystal oscillator, and measure the density of the gas. It is arranged to determine the molecular weight of the gas from the determined or predetermined pressure of the gas and the determined or predetermined temperature of the gas. |
