The Series TFS Flow Switch with adjustable setpoint offers precise flow monitoring of water-based fluids. Units have five selectable flow range settings from 0.2 m/s (0.66 ft/s) to 3.0 m/s (9.8 ft/s). Flow is indicated as a percentage of the flow range on a string of LEDs. The setpoint, adjustable from 15% to 90% of the flow range setting, is displayed as a flashing LED.
