The OPTIFLUX 7300 combines the advantages of non wetted capacitive electrodes, a ceramic liner and the IFC 300 converter. This electromagnetic flowmeter can be used for noisy applications, low conductivities, mediums tending to form an insulating film, applications with high vibrations, and oxidizing, abrasive and toxic mediums.
Instead of conventional electrodes that have a direct contact with the process liquid, OPTIFLUX 7300 has a non-contacting capacitive signal pick-up. The electrodes are designed as large-area capacitor plates, mounted behind the ceramic liner. Because the electrodes have no contact with the medium, unwanted catalytic action with metallic parts is eliminated. A second benefit is that the insulation of electrodes no longer forms a risk. In case of a medium that tends to form a non conductive surface coating on the tube wall, the signal pick up between medium and electrodes will not be interrupted.
