Moore Industries International released a technical white paper exploring the possibilities available to designers of safety instrumented systems using logic solvers as part of a tank overfill protection system. The white paper, "Logic Solver for Tank Overfill Protection," provides examples of straightforward tank overfill protection system topographies and associated safety integrity level calculations. It guides safety engineers through the steps needed to determine the right logic solver for their needs and shows the methodology and calculations for determining applicable logic solvers in SIL 1 and SIL 2 environments. In many cases, discrete logic devices such as the STA Safety Trip Alarm are suitable for use while providing a flexible, low-cost and user-friendly solution.
