Abstract
A viscosity measuring method and viscometer device for remotely determining viscosity of fluids within an enclosed container. The viscometer device comprises a vertically-oriented tubular probe which contains a tube enclosed by multiple adjacent electromagnetic coils, and the tube contains a movable magnetizable core-float member. When measuring viscosity of a fluid, the movable core-float member is first magnetically lifted to the upper end of the tube by sequential energizing and deenergizing of the electromagnetic coils, then the core-float is allowed to fall freely through the fluid to the lower end of the tube. The fluid viscosity is determined by the elapsed time for the core-float to fall through the fluid. The viscosity measuring method and viscometer device is particularly useful inside a reactor containing fluid and operated at high pressure and temperature conditions.
