Description
Rheometers measure the forces (like shear) associated with a flowing substance. Typically, the flowing substance is much thicker than a liquid (like concrete). A rheometer does not simply measure flow, but also measures the effects of flow at different pressures-especially key characteristics of the flow like shear (how difficult it is to change the flow) or how the flow of a substance tends to drag surrounding materials.
