A new non-touching ultrasonic measuring method of fixed liquid level for pressure containers

摘要

A new non-touching ultrasonic method for measuring the fixed liquid level of containers and its implementing way, based on the penetration attenuation theory of ultrasonic remanent signals container's wall, are first time presented in this paper. For the transducer being only needed to be clung to the outer surface of containers, it is very convenient for the fixing and the sensitivity and reliability also come high. It is especially suitable for measuring and monitoring the upper level of liquid in high-pressure containers and high-corrosive liquid containers.
