Magnetic Level Gauge Technology

The foundation of any level measuring system rests upon the level gauge itself, and for many fluidprocessing industries the new platform of choice is the magnetic level gauge.
In the past, a sight glass was felt to be simpler because it does not have a float. Yet, close scrutiny reveals that a slight glass can possess as many as 50 separate parts. Additionally, the continuous maintenance required to remove and clean the glass is quickly forcing them out of favor. Some users have indicated a six to twelve month payback in maintenance savings alone by replacing their sight glasses with magnetic gauges. The fact that the cushions and gaskets used to seal the glass can be permanently deformed by compression —resulting in possible leaks, stress points, and even potential breakage—is likely the ultimate reason for the demise of sight glasses. This older technology clearly represents a substantial risk for environmental and personnel safety.
Since the visible shuttle/indicator avoids direct contact with process liquids, problems with coating, plating, fouling, fugitive emissions and hazardous material leaks are completely eliminated. This ensures safe leveling of liquids that are toxic, corrosive, or flammable. Magnetic coupling also makes it easier to determine the level of colorless fluids.
