Ideal for a range of upstream and downstream oil/gas applications, petrochemical industry process and plant engineers searching for a precision flow/level/temperature switch for use in liquid, air, gas or for interface service now have the FLT93® Series FlexSwitch™ available.

The FLT93® Series FlexSwitch™ from Fluid Components International (FCI) provides an effective and highly reliable solution in a wide range of applications.

Described as ideal for use in oil/gas upstream production or downstream refining, storage and distribution, the FCI FLT93 Series FlexSwitch provides dependable relief valve monitoring and flare gas flow or leakage detection. It improves plant safety and environmental compliance by helping to assure operators that relief valves and flare gas systems are functioning properly.

The FLT93 Series FlexSwitch’s multi-parameter measurement design is based on more than 45 years of flow and level switch engineering and application experience, providing a rugged long-life instrument. SIL2 rated for ultra-reliability, the switches are found in the world’s most demanding processes and plants. Ex agency approvals are provided for the entire instrument—FM, FMc, ATEX, IECEx and more.

A dual-function instrument, the FLT93 Series FlexSwitch can be configured for flow or level sensing, flow + temperature sensing or level + temperature sensing. A single FLT measures and monitors flow or level and temperature simultaneously with excellent accuracy and reliability. Dual trip points and 6A relay outputs are standard and are assignable to flow, level or temperature.

FCI’s unique sensor technology of the FLT93 Series switches, combined with FlexSwitch temperature compensation circuitry, provide users with unparalleled performance capabilities: Exclusive flow accuracy as precise as ±2 percent of the set-point velocity over ±50°F [±28°C] temperature range; repeatability of ±0.5 percent reading. Level resolution is ±0.1 inch [±2.5 mm]; repeatability of ±0.05 inch [±1.3 mm].  Standard temperature accuracy is ±2.0°F [±1°C]; repeatability ±1.0˚F [±0.6˚C]; improved temperature accuracy is available with factory calibration.

Two standard sensing element configurations are available to meet the user’s most demanding application requirements.
