PROCESS FOR MEASURING FLOW PROPERTIES OF FREE-FLOWING MEDIA

摘要

According to a method for measuring fluid media flow properties, for example liquids, melts and viscous materials, in particular plastic, is introduced a sample of the medium in a measuring cylinder (2, 3, 4) maintained at a determined temperature and is expressed through a nozzle (33) by means of a compression piston (54), the fluidity of the sample being determined by performing measurements. An identification marking (23) of sample material is introduced into a computer (7) and recorded by the latter. The computer stepper control a conveyor (1) for transporting the measuring cylinder (2, 3, 4) and processing devices (17), so that a measuring cylinder (2) provided in a loading station (17) is exposed to a filling device (28, 30, 48, 50, 51) and the measurement sample is transported to a measuring station (17) wherein the plunger (54 ) is operated, the measurement values ​​thus determined (e.g., duration and extent of movement of the piston, pressure upstream of the nozzle) is used by the computer (7) for calculating a measurement result. The conveyor (1) then carries the measuring cylinder (2, 3) to a cleaning station (17) where the cylinder is cleaned by a cleaning device (70, 77), then during the following transportation step it is returned to the loading station (17) to be loaded again. The computer (7) associated with the received identification marking (23) of material with the measurement result and outputs it as fluidity characteristic of the sample.
