Viscotherms are used to determine the viscosity of a fluid; this is done by a small pump being fitted throughout the system of the fluid of which the density is required. This small pump will then produce a constant pressure; this is then forced through a capillary, where the viscosity can be measured by taking pressure readings a certain points off the capillary.
