Inline Oil Viscometer
It's also referred to as an inline oil viscometer for oil or inline oil viscosity meter, celebrated for its exceptional performance in crude oil refining and lubricant production lines. Typically installed in the supply pipeline that conveys oil from storage tanks or pumps to processing units like heat exchangers or blending tanks, it delivers instant viscosity data just before the oil reaches key equipment such as distillation columns or filtration systems. Operating on the principle of measuring how oil's viscosity dampens a vibrating element (like a tuning fork), it feeds real-time data into automated control systems, enabling immediate adjustments to factors like temperature or flow rate to maintain optimal oil viscosity, thus ensuring consistent product quality in the automated production process.
Working Principle
The inline viscometer oil employs an acoustic signal source to excite a metal tuning fork, causing the fork to vibrate at its natural resonant frequency. Notably, this resonant frequency exhibits a direct correlation with the viscosity of the liquid that the tuning fork contacts. Subsequently, the viscosity the liquid can be determined through frequency analysis—with temperature compensation implemented to counteract temperature drift within the system, ensuring measurement accuracy.
