The new FCI SIL-2 safety compliance ensures its customers that the third-party testing organization (TUV Nord) has tested the FLT93 Switch Series and when the product is in use, the process risk is reduced to the designated level.
FCI customers can rely on the company to continually improve the safety and reliability of all of its solutions.
Advanced thermal mass flow switches and flow meters from FCI are recognized worldwide for their precision flow measurement, high reliability in rugged operating conditions, low maintenance, long-life and low cost-of-ownership.
Their highly intelligent microprocessor-based designs feature a no-moving parts thermal mass flow sensor, which makes them ideal for a broad range of industries including: chemical, energy and power, food/beverage, oil/gas, pharmaceutical, water/wastewater treatment and more.
The FCI FlexSwitch Series has established an unmatched industry record of superior performance and reliability.
The advanced FlexSwitch FLT Series features a unique design that monitors flow, level or interface and can perform flow and level sensing simultaneously.
The Flow/Level (FLT) Flow Switch reliably monitors the flow, level and interface of liquids, gases, slurries, syrups, lubricants, coolants and more.
It is ideal for tank level monitoring and pump low-flow protection applications.
The FLT features a wide set-point range, which varies according to service media (liquid, gas or foam), beginning from 0.01 to 5 SFPS (0.003 to 1.5 SMPS) in hydrocarbon-based liquids.
This innovative instrument is ideal for heavy duty industrial environments (FLT93S), pump protection and small process connections requiring a fast, high responsive switch (FLT93L-F Style).
Applications for these switches include pump protection for low flow levels and empty pipe, wet/dry detection, sump level detection, high/low level alarm and control, interface control in separation vessels, foam and sediment interface control, and agitation detection.
The FLT is hydrostatically proof pressure tested to 3500 psig [240 bar] at 70F (21C).
De-rated with temperature, the maximum operation service recommended is 2350 psig [162 bar] at 500F (260C).
Higher pressure ratings and temperature ratings up to 850F (455C) are available with special construction and test certification.
A wide selection of standard and custom process connections can be provided.
The electronic control circuit can be integrally-mounted with the sensing element, or it can be located in a remote location.
The standard enclosure is made from a coated aluminium alloy.
It is suitable for use in hazardous (FM, CSA, and ATEX classified) locations and is rated for NEMA Type 4X (IP66) environments.
The FLT93 Series comes with a three-year warranty and is competitively priced.
