In crude oil extraction and processing, measurement of water content plays vital role. Several methods are available to measure water content in crude oil but most of them are laborious and for offline detection. For an accurate online measurement of water content in crude oil, a novel interface circuit is proposed by using differential capacitive sensor based on modulation technique. This design...
This paper presents a novel interface circuit design for an accurate measurement of water contents in crude oil by using differential capacitive sensors; the latter are immersed in two different liquids. One of them is a pure crude oil considered as a reference medium and the other medium is a mixture of water and crude oil which considered as a liquid under test. The dielectric permittivity of oil-water...
