For measuring the viscosity of a thin planar film of fluid which may be simple, may contain solid particles in suspension, may be a mixture of several fluids, or may be any combination of these; a planar viscometer including (1) a mixing tank, (2) a planar flow generator including in series a long straight cylinder, a long diffuser, a short converging nozzle and a planar transition section of constant section, and (3) means forming a laminar flow passage.
