FIELD: instruments for measuring viscosity of flow in testing equipment. SUBSTANCE: method involves measurement of characteristics of output signal of turbine transducer of usage into pulse frequency; calculation of flow index, processing of measured characteristics in real-time by computer. In addition integral friction on wall τand flow pressure difference ΔPon turbine of usage transducer are measured. Flow density ris also measured. Viscosity index of flow is calculated using equation which is given in invention specification. EFFECT: increased precision. |
