A viscous liquid supply apparatus includes a storage tank (10) that stores viscous liquid, and a pump (14) that supplies the viscous liquid stored in the storage tank to a use point, wherein the viscous liquid supply apparatus is configured with a viscometer (20) that measures a viscosity of the viscous liquid stored in the storage tank, and a replenishment device (30) that supplies replenishment liquid to the storage tank based on the viscosity measured with the viscometer. The viscometer (20) is a rotary type viscometer that has a rotor (23) in a cylindrical shape wherein the rotor is immersed in the viscous liquid and rotates therein, and the rotor is configured with a stirring blade that agitates the viscous liquid inside the storage tank (10).

A conveying device for conveying a viscous material from a container includes a follower plate that can be inserted into the container, and a pump by means of which the viscous material can be conveyed through the follower plate. Moreover, a measuring chamber for accommodation of a measuring sample of the viscous material is provided. The measuring chamber includes a closable material inlet opening for this purpose. A closable disposal line leads away from the measuring chamber. Moreover, a closable material return line extends from the measuring chamber via the follower plate into the container. The conveying device also includes a controller that is designed and can be operated appropriately such that it determines the compressibility of each of multiple measuring samples. The controller opens the disposal line or the material return line to the measuring sample present in the measuring chamber as a function of the compressibility thus determined.
