Instrument For Direct Measurement Of Air Content In A Liquid Using A Resonant Electroacoustic Transducer

Abstract:

This invention relates to apparatus and method for measurement and monitoring of physical properties of materials, such as liquids, and more particularly to acoustic instruments, methods, and systems that automatically measure air content in real-time within liquids, including concrete, mortar, or other hydratable cementitious mix suspensions using resonant electroacoustic transducers that have their radiating surfaces in contact with the liquid.
