FlexSwitch FLT93S monitors and controls flow rates or levels of critical fluids such as foams, emulsion layers, liquids and slurries. Used in harsh plant environments in chemical refining, waste treatment and other industries. Operates over setpoint range in water from 0.01 to 0.5 FPS (0.003 to 0.9 MPS). Level/interface accuracy is ±0.25 inch (±6.4 mm), and measurement repeatability is ±0.125 inch (± 3.2 mm). 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).
