Abstract
An apparatus and method for determining quantity of water and dissolved gases in a fluid system during operation. The method and apparatus uses a sensor on the fluid system to determine the properties during operation by applying NIR (near infrared) Spectroscopy. The detection of water (including discrimination of form of water) is determined using NIR spectroscopy. In one implementation this is done by guiding a laser LED tuned to 5000-5500/cm wavenumbers and beaming the laser through a transparent window into a reservoir of fluid.
