Oil viscosity is an important physical property indicator which represents how viscose oil is under certain temperature environment. It has strong influences on some production process and oper-ating machines. Therefore, the study on accurate and fast kinematic oil viscosity measurement and automatic control has very important practical applications to meet production control and machine operation purposes and requirements. This essay is aimed to introduce a time-dependent based automatic measurement and controlling system of linear kinematic oil viscosity. This article discusses and analyses the feasibility of the study from system assembly, principle of online kinetic viscosity measurement, kinetic viscosity automatic system and control, working theories, and malfunction alarming. It also applies the appliance in practical measurement and automatic control of heavy oil kinetic viscosity for diesel engine. It is shown that time dependent magnetic float measurement is feasible in the online kinetic viscosity measurement and automatic control;the results are valid and can be applied in practical applications.
