FlexSwitch FLT93S

The FlexSwitch FLT93S Flow/Level/Temperature Switch from Fluid Components International (FCI) performs monitoring, controlling and alarming of flow rates or levels of critical fluids such as foams, emulsion layers, liquids and slurries.

The FLT93S Switch is a duel-function insertion-style instrument which offers either flow/temperature sensing or level/temperature sensing in a single devise.  A single FLT93S switch measures and monitors flow or level and temperature simultaneously with accuracy and reliability. Duel 6A relay outputs are standard and are assignable to flow, level or temperature.

FCI’s FLT93S Switch operates over a wide 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). 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 FLT93S Switch relies on the specific heat transfer properties of the media to identify the interface of different products with similar densities for reliable control in separation tanks and other vessels. This automatic compensation adjusts the instrument for changes in operating environment temperatures. This ensures the trip points will remain accurate and will prevent false alarms or alarm failures to improve end-product quality, to maximize safety and to allow alarms to be set with a narrower set range point.
