摘要： Patent of invention "Process for metering hydrogen permeated in a metallurgical structure", refers to a process for metering permeated hydrogen flow in machines, equipment, piping, or other metallic apparatus, through a sensor that uses the properties of a couple of dissimilar materials, in construction and installation that are suitable to measure electrical values between a metering couple and a reference couple. The measured value is a function of the flow rate of hydrogen that permeates the metallic surface under monitoring. In consequence, we obtain a process for measuring hydrogen corrosion or hydrogen flow through an apparatus.
