Description

Известен способ измерени  физико-химических характеристик жидки.х сред, например в зкости h и плотности р, при -помощи вибрациониого преобразовател . Предлагаемый способ позвол ет повысить точность измерений. Это достигаетс  тем, что одеовременно измер ют частоту колебаний резонансной системы преобразовател , погруженного в исследуемую среду, и параметр, св занный с диссипативными потер ми в той же жидкости, например амплитуду, и по полученным данным рассчитывают искомые величины . Сила сопротивлени  со стороны жидкости преобразователю, соверитающему в ней поперечные колебани , зависит от Уhp и р. При этом на амплитудный параметр f колебаний вибратора вли ет диссипативный фактор)/-71р, а собственна  частота / колебаний вибратора. Главным образом, зависит от р. Таким образом, задача сводитс  к определению зависимостей , /г pi (a,f) и ,, (а J) С последующим непосредственным измерением а и f и вычислением Лир. Полученные зависимости имеют вид дл  режима свободных колебаний „ 1 1 1 /ь Р (   - f f , 1 / 1 1 h - ( CiС, 1 .- , / V Я«/ Р где bi-bz, Ci и Cz - посто нные; дл  непрерывного режима --f+(.-)-. )т где AI-Ai, Bi и BZ - посто нные. Дл  определени  в зкости и плотности жидкости вибрационный преобразователь помещают в исследуемую жидкость, измер ют частоту колебаний преобразовател  и амплитудный параметр, а затем провод т расчет по приведенным формулам. Предмет изобретени  Способ измерени  физико-химических характеристик жидких сред, например в зкости и плотности, при помощи вибрационного преобразовател , отличающийс  тем, что, с целью повышени  точности измерений, одновременно измер ют частоту колебаний 3 резонансной системы преобразовател , погруженного в исследуемую среду, и параметр, св занный с диссипатиВНыми потер ми в той 4 же жидкости, например амплитуду, и по полученным данным рассчитывают искомые величины .There is a known method for measuring the physicochemical characteristics of liquids, such as viscosity h and density p, with the aid of a vibration transducer. The proposed method allows to increase the measurement accuracy. This is achieved by measuring the oscillation frequency of the resonant system of a transducer immersed in the medium under investigation, and the parameter associated with dissipative losses in the same fluid, for example amplitude, and the values obtained are calculated from the data obtained. The resistive force on the fluid side of the transducer, which is compatible with transverse oscillations in it, depends on Uhp and p. In this case, the amplitude parameter f of the vibrator vibrations is influenced by the dissipative factor) / - 71p, and the natural frequency / vibrations of the vibrator. Mainly dependent on p. Thus, the task is reduced to determining the dependences, / r pi (a, f) and, (a J), followed by direct measurement of a and f and calculation of Lear. The dependences obtained have the form for the mode of free oscillations 1 1 1 1 / Р Р (- ff, 1/1 1 h - (CiС, 1 .-, / V Я «/ Р where bi-bz, Ci and Cz are constants; for continuous mode, - f + (.-) -.) where AI-Ai, Bi and BZ are constant. To determine the viscosity and density of the fluid, the vibratory transducer is placed in the test fluid, the oscillation frequency of the transducer and the amplitude parameter are measured, and The calculation is then carried out using the following formulas. Subject of the Invention A method for measuring the physicochemical characteristics of liquid media, such as viscosity and density, with Vibration transducer methods, characterized in that, in order to improve measurement accuracy, the oscillation frequency 3 of the resonant system of the transducer immersed in the medium under study is measured simultaneously, and the parameter associated with the dissipated losses in that 4 liquid, for example amplitude, the obtained data are calculated values.
