METHOD OF CONTINUOUS MEASUREMENT OF VISCOSITY OF LIQUID AND DEVICE FOR ITS REALISATION Russian patent published in 2017 - IPC G01N11/08 

FIELD: measurement technology.

SUBSTANCE: in the proposed method of measurement of viscosity in the measuring chamber, in which the diaphragm orifice is integrated, by metering pump in small portions served investigated liquid pulse method. Before the diaphragm the pressure pulse is created, fixed pressure sensor from which the signal is transmitted to the control unit and the information processing in which the processing and conversion of the signal, the calculation of viscosity and output information on the electronic board are also created. Device for implementing the method comprises a reactor, a heat exchanger, a temperature sensor, a metering pump, a measuring chamber, in which the aperture is integrated with the orifice, a pressure sensor, a check valve, the control and processing unit comprising a control unit pump- dispenser unit temperature control in the heat exchanger unit converting the digitized signal from the pressure sensor and calculating the viscosity of an electronic board.

EFFECT: providing the possibility of continuous measurement of fluid viscosity, the possibility of measuring the viscosity in a continuous manner directly on the production line, the minimum amount of sample liquid without causing interference in the process plant operation, the temperature of the test liquid are adjusted to the optimum, increased accuracy, providing a reliable control over the process.
