Abstract: Development of new transducers of water content of oil with higher measurement accuracy and sensitivity is an important task, since the use of existing electric moisture meters of both commodity and crude oil is significantly limited in operating conditions. A considerable additional error up to 1-5 %, occurs when the resistance of the formation water in the emulsion bypasses the capacity of the measuring sensor. The article discusses the digital pulse electric transducer of water content with automatic error correction, taking into account the influence of the conductivity of water-oil emulsion

Abstract: Development of new measuring converters the moisture content of oil, with higher accuracy and sensitivity of measurement, is an important task, since the use of existing commercial moisture meters as well as crude oil with some restrictions in operation. The article deals with the effects on the capacity of the sensor pulse signals, resulting in moisture content may determine the transient characteristics.
