Thermal flow switch FLT93S

for gasfor liquidsinsertion

The FLT93S insertion type FlexSwitch for flow and temperature monitoring represents the first true technological breakthrough in thermal technology in over a decade. This product was designed for heavy industrial environments including high temperature and high pressure. FCI is the only thermal manufacturer providing temperature compensation to ensure set point accuracy for process temperatures that vary up to ± 100°F. The FLT93S is easily field-configured or factory preset, providing unparalleled flexibility, accuracy and stability for all multiple process sensing and switching requirements. Applications Pump protection Cooling water/heat exchangers Drain line flow Safety spray nozzle monitoring Oil well system testing Relief valve monitoring Venting assurance Specifications For Flow Service - Setpoint Range: Water-based Liquids: 0.01 to 3.0 fps [0.003 to 0.9 mps] Hydrocarbon-based Liquids: 0.01 to 5.0 fps [0.003 to 1.5 mps] Air/Gas: 0.25 to 120 sfps [0.08 to 37 smps] at standard conditions of 70° F [21.1° C] and 14.7 psia [1.013 bar(g.
