Abstract:

The capillary narrow rheometer is developed, in which micrccomputer data collection and control system are adopted. It is used to make automatic on-line and off-line rheological measurements, especially in geolog-y and of drilling fluids. Its specification is good, with relative error not more than 3% in automatic measurement, and the shear rate ranging from 。
