U Tube Reverse Flow Viscometer

Reverse flow U-tube viscometer measures viscosity by timing liquid flow upward against gravity between marks, suitable for opaque or volatile fluids.

U Tube Reverse Flow Viscometer

Calibrated U Tube Reverse Flow Viscometer as per BS/IP/RF and ASTM D 446 for opaque liquids - Calibrated 

Description :

U-tube reverse flow viscometer is a type of capillary viscometer primarily used to measure the kinematic viscosity of opaque Newtonian liquids.Designed for opaque liquids: It's specifically engineered to overcome the challenge of observing the meniscus which is the curved surface of the liquid when using standard  viscometers with dark or opaque fluids. The liquid is drawn up into the capillary and allowed to flow downwards through a timing section, wetted only during the    actual measurement process.The viscosity is determined by measuring the time it takes for a specific volume of the liquid to flow between two marked points on  the viscometer.
