  • Capillary viscometer apparatus for an uncomplicated determination of flow characteristics of fluent materials
    Patent number: 5331843
    Abstract: A capillary viscometer apparatus comprises a measuring cylinder (3) having an axially-movable piston (2) which is moved by a drive (1). The measuring cylinder (3) and the piston (2) define a measuring space (4) which communicates with a capillary tube or bundle (6) and a differential pressure gauge (7). A pressure difference between the measuring space (4) and a tested medium (12) is registered and processed by a signal-processing unit (9). A speed of the piston (2) is determined by means of a displacement-time measuring device or a speed measuring device (8) and this information is then transmitted to the signal-processing unit (9).
