Abstract

Methods of increasing the accuracy of waveguide-acoustic methods of measurement in order to obtain highly accurate level gauges are presented.

A system with additional reflectors, which enables one to take into account the actual velocity of sound and also methods of combating interference are considered. A method of reducing the minimum measurement distance between the instrument and the boundary of the media is described.
