Patent ID: 8800301

Claim:
Capacitive separator device comprising: a body formed by a solid part and a tank perforated in said solid part, defined by tank walls, said tank including an upper threaded opening, a lateral threaded opening, a fluid inlet adapted for the introduction of a fluid to be separated inside the tank into gases, hydrocarbon and water, and at least three outlet means adapted for the outflow of gases, hydrocarbon and water, respectively, a hydrocarbon probe fixed in the upper threaded opening which reaches the interior of the tank, at least one hydrocarbon level measurement condenser formed by said tank walls, the hydrocarbon separated from the fluid, which acts as a dielectric, and the hydrocarbon probe, a first oscillator circuit connected to the hydrocarbon level measurement condenser which measures the electric capacity of said hydrocarbon level measurement condenser and which generates a frequency signal proportional to said electric capacity providing a hydrocarbon level signal, a first reference oscillator circuit which operates in parallel and at the same temperature as the first oscillator circuit, which generates a reference hydrocarbon level signal and compensates the errors caused by the variations in temperature of the first oscillator circuit, a hydrocarbon level measurement module connected with the first oscillator circuit and with the first reference oscillator circuit that receives the hydrocarbon level signal and the reference hydrocarbon level signal respectively, a water probe fixed on the lateral threaded opening which reaches the interior of the tank, at least one water level measurement condenser formed by said tank walls, the water separated from the fluid, which acts as a dielectric, and the water probe, a second oscillator circuit connected to the water level measurement condenser which measures the electric capacity of said water level measurement condenser and which generates a frequency signal proportional to said electric capacity providing a water level signal, a second reference oscillator circuit which operates in parallel and at the same temperature as the second oscillator circuit, which generates a reference water level signal and compensates the errors caused by the variations in temperature of the second oscillator circuit, and a water level measurement module connected with the second oscillator circuit and with the second reference oscillator circuit that receives the water level signal and the reference water level signal respectively.
