JPS6429732A - Method and device for continuously measuring viscosity of fluid in line - Google Patents

Abstract

PURPOSE:To directly and continuously measure the viscosity of a fluid without providing a bypass, and to simplify the device at low cost by leading the fluid to a measuring tank of the outside so as to hold the same level as the upper face of the fluid in a mixing tank. CONSTITUTION:A capsule B is floated by a float on the upper face 29 of a fluid in a measuring tank 9. In such a case, a sensitive plate of the capsule B is inserted into prescribed depth from the fluid upper face 29. Such a depth can be adjusted from the outside by graduation of the outside surface of the float, by bringing a vibration type viscometer to an up-and-down motion by turning a screw of the capsule B. By an inflow control valve 5 and a discharge valve 6, the liquid quantity in a mixing tank 2 increases or decreases, and by following it, the liquid level in the measuring tank 9 also moves up and down, and the capsule B moves up and down by following the up-and-down motion of the fluid upper face 29, and in a state that the sensitive plate are always inserted into prescribed depth from the fluid upper face 29, the viscosity of the fluid can be measured continuously. Also, the device can be simplified at low cost.
