  • Method and apparatus for measuring a parameter of a gas in isolation from gas pressure fluctuations
    Patent number: 5325861
    Abstract: In measuring a selected parameter of a test gas in isolation from gas pressure fluctuations, a pump draws the test gas through a storage capacitor into a sensor, storing the gas in the storage capacitor. A valve closes a fluid flow path which admits the test gas to the storage capacitor and opens a fluid flow path between the storage capacitor and a constant pressure alternate gas source, isolating the storage capacitor and the sensor from pressure fluctuations in the test gas. The storage capacitor prevents any mixing of the test gas with the alternate gas until measurement of the selected parameter has been accomplished.
