METHOD AND MEASURING ARRANGEMENT FOR MEASURING GAS CONTENT OF FLUID

摘要

The invention relates to a method and a measuring arrangement for measuring the gas content of a fluid (13). The fluid (13) comprises gas bubbles. In th e method, microwave radiation (20) is transmitted through the fluid (13) and a signal (7) indicating the travel time, phase or amplitude of the radiation (20) is formed in a microwave measuring device (16), and a gas measuring equipment (18) determines the gas content of the fluid (13) by means of the signal (7).
