Abstract:Floater based liquid level fiber optic sensors, optic coder based liquid flow fiber optic sensors and shutter based negative pressure fiber optic sensors are developed for a distributed integrated production monitoring and control system of oilfield united stations. The control system can carry out the inspection of the oil and water level in a tri-phase separator and realize the remote transfer of signals. The inspection accuracy of liquid level reaches ± 2 mm, the system control accuracy is up to ±5 cm, and the pressure control accuracy is ± 2 kPa.
Keywords:oilfield united station fiber optic sensor liquid level sensor flow sensor negative pressure alarm monitoring
