What are water in oil monitors?
Water in oil monitors are used to detect the presence of moisture or water in hydrocarbons. Several measurement technologies are available. Some devices extract a sample and then boil off the water which can be weighed or measured.. Colorimetric devices use a catalyst to change a sample’s color for comparison to a color chart or analysis with a spectrophotometer. Infrared (IR) water in oil monitors measure the amount of absorbed energy. Ultraviolet (UV) monitors are similar to IR devices, but do not extract hydrocarbons from water. Instead, they emit UV light at a specific wavelength to determine the amount of light that is absorbed. Fluorescence devices also use a UV light source, but measure fluorescence intensity rather than light absorption. Similarly, light scattering devices measure how water in oil causes light to refract in a predictable manner that can be monitored. Measurement technologies for water in oil monitors also include microwave, acoustic, and capacitance methods. Ty
