We used the methods of computing indirect measurement uncertainties to derive causality criteria for systems of linear algebraic equations. The methods were employed to analyse the accuracy of physical quantity measurement techniques. The paper considers the methodology behind criterion derivation using a system of two linear algebraic equations as an example. We present the results of relying on these criteria to analyse non-contact aerodynamic techniques of simultaneously measureing density and surface tension in liquids
