FIELD: measuring engineering.
SUBSTANCE: method comprises measuring at least one parameter for at least one fluid in pipe with the use of a set of pressure gauges distributed in space and arranges along the pipe axis, determining the sound velocity by processing signals from the distributed pressure gauges, and calculating in the logical device the percentage of components in mixture, e.g. water concentration, or any other parameter of the mixture or fluid, e.g. the Max number, which depends on the sound velocity.
EFFECT: expanded functional capability and reliability.
