Paraffin Deposit Affects the Precision of Vibrating Densimeter

The article briefly introduces the operating principle of vibrating densimeter. The authors consider that the paraffin deposit has influence on the precision of vibrating densimeter during inline custody transfer metering for the high wax content oil. To improve the precision of vibrating densimeter, some measures on controlling the temperature of oil, increasing the frequency of wax removal, and compensating the error are put forward.
