| 摘要 |
<p>The invention makes it possible continuously to measure the rate of corrosion by a fluid, in geothermal installations also, while ensuring a complete and lasting electrical insulation between the electrodes of the apparatus. It comprises a longitudinal support (10), at least two electrodes (12) positioned on the longitudinal support (10), which have a given diameter and are in contact with the fluid. The device also comprises means of electric connection (22) of these electrodes (12), which are protected from the fluid, and separators (18) positioned between the electrodes (12) in order to insulate them electrically. The separators are in contact with the fluid, have at least one part, the maximum diameter of which is greater than that of the electrodes (12), and have a discontinuous external surface (16) in order to create discontinuity of any deposits of conductive materials on the external surface of the measuring apparatus. Application in continuous measurement of the rate of corrosion by geothermal fluids. <IMAGE></p> |
