Abstract
Mathematical relations which make it possible to estimate the effect of errors in determination of pipeline parameters on the error in measurements of the density of a binary mixture with reference to a cement mortar is considered. The results of calculations of the mass radiation attenuation coefficients as functions of the gamma-quantum energy are given for main components of the tested object with allowance for variation of the cement formula. On the basis of the data and formulas obtained, which establish requirements for the recorded signal of a densimeter, the presence of optimum ranges of the gamma-quantum energies of the source and a significant in uence on the signal and the necessity to take the multiplicative component of the instrumental error of the densimeter into account are demonstrated. Recommendations on the choice and calculation of particular parameters and optimization conditions of the densimeter are given with reference to the formulated problem of testing.
