Water cut meters measure BS&W or the content of water in crude oil. They operate using multiple technologies, including capacitance, optical, density and microwave. Capacitance probes rely on the difference in the dielectric constant of oil and water. As the percentage of water (water cut) increases, so to does the dielectric property of the fluid. Optical meters generally emit a signal in the IR spectrum and measure the absorption, reflection and scattering of the signal due to the oil phase... Density can be used to measure water cut in light oil flows by measuring the combined density of water and oil and comparing that against the known density of the individual phases. Finally, microwave meters measure multiple electronic properties (complex permittivity) of the fluid to determine water cut.
