With its no-moving parts flow/level sensor housed in a stainless steel package and NEMA 4X enclosure, the robust SIL-2 rated FLT93 Series Switch from Fluid Components International (FCI) is ready for the most punishing heavy marine seawater, acidic or alkaline fluids and wash-down cycles encountered in a wide range of industrial processes and plant environments.
The field-proven FLT93 Switches provide air/gas flow or point level measurement wherever exposure to seawater, salty air, harsh process fluids and heavy wash-downs are a requirement. Its flow/level sensors come in stainless steel, Hastelloy or other exotic metals for demanding service environments.
Aboard offshore oil/gas platforms and large floating, production, storage and offloading (FPSO) vessels as well as other types of marine cargo and passenger ships, the continuous exposure of ordinary flow/level switches to corrosive sea water and air is an issue. The FLT93 Switch with its stainless steel construction and NEMA 4X rating performs highly dependable flare gas and safety relieve valve leakage measurement as well as many other tasks.
In oil/gas refineries and in many chemical plants, flow/level instruments are exposed to a wide range of harsh catalysts, solvents and other corrosive fluids that over time can affect measurement accuracy in less robust instruments. The rugged design of FLT93 makes it a perfect fit in these harsh conditions.
The rugged FLT93 switch is hydrostatically proof pressure tested to 3500 psig [240 bar (g)] at 70°F [21°C]. De-rated with temperature, the maximum operation service recommended is 2350 psig [162 bar (g)] at 500°F [260°C].
