Fluid Components International (FCI), a global company offering innovative solutions for sensing, measuring and controlling flow and level of air, gases and liquids, recently announced its new FlexSwitch^® FLT93S Flow Switch specially designed for process and plant engineers who need to monitor fugitive emissions from compressors, pressure relief valves, pumps and other gas flowing components.

According to FCI, the FLT93S Switch is the ideal plant preventative maintenance and safety tool. Its high sensitivity and ability to detect and alarm on very low flows offers fast response leak monitoring and detection of gas flows. It provides early warning and process shut-down signals that can prevent damage to these expensive components and their processes as well as reduce the probability of accidents. 

The FLT93S Switch operates over a wide gas flow sensitivity range from 0.25 to 120 SFPS (0.08 to 37 SMPS).  Accuracy is ±0.5 percent of reading or 2 SFPS (0.06 NMPS). The standard FLT93S withstands operating temperatures from -40 to 350°F (-40 to 177°C), and an optional configuration is available for temperatures from -100 to 850°F (-73 to 454°C). The full instrument has global agency approvals of FM, CSA, ATEX and IEC for hazardous, Ex environments and has SIL 2 compliance rating.

With its advanced thermal dispersion mass flow sensor, the FLT93S Switch features built-in temperature compensation, which ensures repeatable and reliable operation, even in extreme environments, such as those found in the high temperature chemical refining and other process industries.
