Claim:
1. An apparatus to measure water content and pH of a flowing multiphase fluid mixture of water and oil, the apparatus comprising: a first enclosure and a second enclosure spaced apart with a spacer to define a flow passage, wherein each of the enclosures are sealed and include a cavity; a first layer of an oleophobic coating applied to external surfaces of the first enclosure, the second enclosure and the spacer; the flow passage having an inlet and an outlet for the continuous passage of the flowing multiphase fluid mixture in through the inlet and out through the outlet of the flow passage; a water content sensor comprising an infrared light source arranged in said second enclosure and at least one photodetector arranged in said first enclosure on opposite sides of the flow passage such that light from the light source is passable through the second enclosure, through the flowing multiphase mixture in the flow passage, and through said first enclosure and is 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:
