APPLICATION OF ULTRASONIC METHOD FOR MEASURING THE SOUND VELOCITY IN A MEDIUM TO DETERMINE THE TEMPERATURE CHANGE AND FLUCTUATIONS

摘要

There are application in technology processes where the fast determination of the temperature changes is important to achieve a stable process. The standard temperature sensors has a specific time-period to provide the information about the real temperature of the media. To get a fast response there is a possibility to use an ultrasonic method to determine the change and the real temperature as well. The goal of this study is to test the response time, correlation and reliability of ultrasonic measurement method for determination of water temperature as a part of further drinking water studies and analysis.
