A cylindrical sensor and outer barrel are separated 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 water percentage. Capacitance technology has been used to measure water in oil for a long time and is an accepted principle. We have enhanced Loop Powered EASZ-1 BS&W with stable microprocessor based electronics which do not have the associated 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, something that has been the wish of clients in the oil industry. Watercut Monitor is a solid state electronic instrument that determines the percent watercut in an oil emulsion without requiring the physical separation of the fluids. The capacitance probe technique employed by the Watercut Monitor allows the emulsion stream to be continuously surveyed. The frequency generated by the capacitance probe is determined by the watercut of the emulsion stream in the probe. The Watercut Monitor calculates capacitance measurement by digital techniques. The result is a 4-20mA output signal which varies linearly with watercut. The cut monitor is run on loop power and easy to install. The Watercut Monitor range is site or user selectable from 0 –1%, 0-3%, 0-10%, 0-25% and optionally 0-65% EASZ-1 BSW FEATURES • Microprocessor based electronics Loop powered with user selectable ranges • Serial interface for onsite or LAB adjustments if necessary • Easy to remove PCB Card

So, in other words, water is capable of storing much more energy per volume unit than the average oil. It is important to understand that any changes to the oil that affects the dielectric properties of the oil...
