The FLT93 switch (photo) is a ruggedized, liquid-level and flow sensor that helps processors comply with the National Fire Protection Association (NFPA) Code 30 safety requirements, which aim to reduce hazards associated with the storage, handling and use of flammable and combustible liquids. One of the most common safety-switch applications is filling storage tanks. FLT93 switches detect tank overfilling conditions, issue warning alarms and provide control for liquid shutoff or diversion. The switches also provide alert warnings any time there is a change in a tank’s dry-to-wet condition, including the entry of water into the tank. In fluid-dispensing areas, airflow switches monitor ventilation air systems for airflow to ensure their operation and warn of any system failure. — Fluid Components International LLC (FCI), San Marcos, Calif.
