Abstract: A viscosimeter for measuring the viscosity of a solution in a solvent includes flow resistances having the smallest possible thickness and a small volume compared with all other parallel and following capillaries in a flow conduit system with two legs. The flow conduit system has three parallel flow circuits among which at least two flow circuits are connected by a differential pressure sensor or sensor for differential pressure. The arrangement includes an inlet which divides into two legs, wherein one of the two legs includes a pressure reducing element, a following branch going to a differential pressure sensor and a pressure reducing element in the feeding conduit to a junction which runs into an outlet conduit. The other leg starting from the branch point includes a pressure reducing element which is connected to the differential pressure sensor and to a resistance capillary in the conduit.
Abstract: A viscosimeter for measuring the relative, intrinsic or inherent viscosity of a solution in a solvent with at least one flow resistance and one feeding point for the solution to be examined in a conduit system as well as with respective manometers on the flow resistance which are coupled with a differential amplifier, wherein the viscosimeter includes flow resistances such as disk-shaped or leaf-shaped Venturi nozzles or different KV flow resistances with the smallest possible thickness and with a small volume with respect to all other parallel and following capillaries in a flow conduit system with two legs which contains in the first leg at least three pressure reducing elements, for example capillaries, whereby behind the capillary following the branch point a pressure manometer is provided for with a connected bigger vessel, whereby behind further capillaries connected with each other with different diameters and with a big volume which corresponds to 100 to 1000 times the KV flow resistance in the second
