The present disclosure relates to systems and methods for determining a rheological parameter of a fluid within a wellbore. The methods comprise receiving a plurality of differential pressure measurements of a fluid within a flow region of the wellbore; storing the plurality of differential pressure measurements; generating a curve based on the plurality of differential pressure measurements; and determining the rheological parameter of the fluid using the curve. The systems comprise a conduit arranged in a wellbore; a plurality of pressure sensors along the conduit configured to measure pressure of the fluid within the wellbore; and a processing device. The processing device is configured to: receive a plurality of differential pressure measurements of the fluid from the pressure sensors; store the plurality of differential pressure measurements; generate a curve based on the plurality of differential pressure measurements; and determine the rheological parameter of the fluid using the curve.
