Abstract
An apparatus and method to measure water content and water pH of multiphase fluid mixtures of water and oil. The apparatus employs a water content sensor containing an infrared light source and a photodetector. The pH sensor includes a pH indicator that exhibits a color change in an oleophobic coating including an image recording device. The apparatus and method may be applied to measure water fraction and pH within oil/water pipelines.
Claims20
An apparatus to measure water content and pH of a multiphase fluid mixture of water and oil, the apparatus comprising:
- a water content sensor comprising an infrared light source and at least one photodetector arranged such that light from the light source is passable through the multiphase mixture and detectable by the photodetector, the photodetector arranged to convert the detected light from the light source to an electrical output indicative of the water content of the multiphase fluid mixture,
- a pH sensor comprising a pH indicator that exhibits a color change indicative of a pH level of the water in an oleophobic coating including an image recording device arranged to record the color change of the pH indicator.
A method for measuring water content and pH of multiphase fluid mixtures of water and oil comprising:
- supplying a water content sensor comprising an infrared light source and at least one photodetector arranged such that light from the light source is passable through the multiphase mixture and detectable by the photodetector, the photodetector arranged to convert the detected light from the light source to an electrical output indicative of the water content of the multiphase fluid mixture;
- supplying a pH sensor comprising a pH indicator that exhibits a color change indicative of a pH level of the water in an oleophobic coating including an image recording device arranged to record the color change of the pH indicator;
- measuring the fraction of water and its pH in said multi-phase fluid mixture.
