A system (100) for measuring drilling fluid properties includes a capillary rheometer (134) that is adapted to measure viscosity parameters of drilling fluid. The capillary rheometer (134) includes a feed chamber (135), the feed chamber (135) having a cavity (135a, 135b), at least a first drain port (144) for draining fluid out of the cavity (135a, 135b), a double wall (136) defining an annulus (140) that opens to the cavity (135a, 135b), and a feed port (142) in an outer portion (136a) of the double wall (136) that is in fluid communication with the annulus (140). The capillary rheometer (134) also includes at least a first capillary tube (146) coupled to at least the first drain port (144). Additionally, the disclosed system (100) further includes a pump (102) that is adapted to pump fluid to the feed port (142). |
