A viscometer system to determine the viscosity of a fluid utilizes an existing flow cell, which maintains a calibrated constriction that is defined by a predetermined constant value K is disclosed. The viscometer system is adapted for use with the flow cell and includes a pair of pressure transducers with one at the input of the flow cell and another at the outlet of the flow cell. During operation, particles within the fluid pass through the flow cell, whereby the positional change of the particles over a predetermined period of time allows the system to calculate the flow rate of the fluid. The system also identifies the change in pressure of the fluid as it passes through the flow cell, such that the pressure change, flow rate, and the constant value K are processed to calculate the viscosity of the fluid being analyzed.
