Claim 3:
4. The automatic measuring method according to claim 2, wherein: the flow rate and the pressure dissipation in conventional pipelines are calculated with the obtained rheological parameters for different flow models; use the different calculation model for different flow models to calculate the pressure dissipation first; then the flow rate is calculated by the relation between pressure dissipation and flow rate:, q
