Fluid Components Intl. FlexSwitch® FLT93S flow switch Fluid Components Intl. has created its FlexSwitch® FLT93S flow switch to monitor fugitive emissions from compressors, pressure relief valves, pumps and other gas-flowing components. The ideal plant preventive maintenance and safety tool, according to the company, the FlexSwitch further delivers:

  • The ability to detect and alarm on very low flows for fast response in leak monitoring and detection of gas flows.
  • Early warning and process shut-down signals to prevent damage to process components, as well as reduce the probability of accidents and government incident reporting. 
  • The power to ensure gas flow system components are operating correctly. 
  • The inclusion of dual 6A relays, which are fully user-settable for any high, low, high/high or low/low detection and trip scenarios.
  • Operation over a wide gas flow sensitivity range — from 0.25 to 120 SFPS (0.08 to 37 SMPS). 
  • An accuracy of ±0.5 percent of reading or 2 SFPS (0.06 NMPS).
  • Operating temperatures from -40° to 350°F (-40° to 177°C). 
  • 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. 
  • An aluminum alloy enclosure rated for NEMA 4X and IP66. 
  • Simplified installation as an insertion-style instrument.
  • Compliance with FM, CSA, ATEX, IEC for hazardous environments and SIL 2.
