EESIFLO's BS&W analyzer uses the principle of dielectric strength. A cylindrical sensor and outer barrel are seperated from each other and form the electrodes of a coaxial capacitor. The oil sample flows between the cells as a dielectric fluid, changing the capacitance of the assembly proportionally with the change in dielectric constant of the fluid. The measured capacitance is converted to water percentage. Capacitance technology has been used to measure water in oil for a long time and is an accepted principle. EESIFLO has enhanced is Loop Powered EASZ-1 BS&W with stable microprocessor based electronics which do not have the asscociated problems of the effect of temperature changes on the dielectric constant, since our built in temperature sensor and electronics compensate.

This in turn means higher accuracy and stability at an affordable price.
