FIELD: measurement of chemical and physical characteristics of fluid media, in particular their viscosity and density. SUBSTANCE: probe is accelerated to velocity influenced by valve and direction, present values of heights hoccupied by probe are measured at required time moments t,t, as well as of horizontal component of way lcovered by probe or for influenced heights hand way ltimes of their reach are measured. Required intermediate values, in particular, mean values of components of velocity of movement of probe over proper sections of vertical Vand horizontal Vcomponents of movement path are calculated. Formulas for calculation of density and viscosity of liquid are obtained on the basis of law of conservation of energy and second Newton's law and measured values of density and viscosity of liquid are calculated for each direction of movement. Resulting values of viscosity and density of liquid are estimated as mean or weighted mean values of their values by directions of movement. EFFECT: improved metrological measurement characteristics thanks to performance of measurement under velocities of probe movement limited in value. 1 cl, 1 dwg |
