## Calculation

### Transducer Constants

The transducer constants are calculated by:

Where | ||
---|---|---|

RD_{x} |
= | Relative density of calibration gas x |

RD_{y} |
= | Relative density of calibration gas y |

τ_{x} |
= | Periodic time associated with calibration gas x |

τ_{y} |
= | Periodic timeassociated with calibration gas y |

### Relative Density

The relative density is calculated by:

K0 & K2 | = | Transducer constants |

τ | = | Periodic time associated with the measured gas |
