Abstract
A method of determining viscosity can include connecting a bypass flow passage in parallel with a main flow passage, connecting a mass flowmeter and a variable flow restrictor in the bypass flow passage, and connecting at least one viscometer to the bypass flow passage. A rheology measurement apparatus can include a bypass flow passage connected in parallel with a main flow passage, a mass flowmeter connected in the bypass flow passage, and a pipe viscometer connected in the bypass flow passage. Another bypass flow passage may be connected in parallel with the main flow passage, with another mass flowmeter connected in the second bypass flow passage.
