Rheology modifiers are vital additives used in almost every coating and ink to adjust the rheological characteristics. Apart from getting desired viscosity, these additives also help in controlling paint shelf stability, ease of application, open time / wet edge and sagging. Before we dig into the use of rheology modifiers, it may be useful for

Falling ball viscometers work in a similar fashion to falling piston viscometers. With this type of viscometer, a ball is dropped into a sample of the fluid being measured. The dimensions of the ball are already known, so viscosity is determined by timing how long it takes the ball (again, using timeoffall seconds) to fall through the fluid via gravity.
