“…In this work, these parameters A(T) and B(T, p) were determined through the measurement of the oscillation period of a reference fluid and of the evacuated tube over all the experimental range, following the method developed An important feature concerning mechanical oscillator densimeters is the effect of the sample viscosity on the density measurements. The correction factor depends not only on the sample viscosity but also on the specific design of the oscillator tube [29,30]. For the DMA HPM model, Segovia et al [12] have obtained very recently, from data provided by Anton Paar, the following correlation equation:…”
