FLT93L FlexSwitch® Flow Switch
Flow Switch SummaryThe FLT93L inline type FlexSwitch for flow and temperature monitoring
represents the first true technological breakthrough in thermal
technology in over a decade. FCI is the only thermal manufacturer
providing temperature compensation to ensure set point accuracy for
process temperatures that vary up to ± 100° F. The FLT93L is easily
field-configured or factory preset, providing unparalleled flexibility,
accuracy and stability for all multiple process sensing and switching
requirements.
