The Model L8 Flotect® Liquid Level Switches are oat switches constructed of polyphenylene sulde, Ceramic 8 and 316 SS. This liquid level switch provides accurate set point control of liquids with specic gravities as low as 0.6.

FEATURES/BENEFITS

• Features a leak proof body and oat constructed from tough, durable polyphenylene sulde which has excellent chemical resistance

• Liquid level snap switch is magnetically actuated with no direct mechanical linkage to leak or fail, assuring longer life and decreased maintenance costs

• Quick and easy installation with simple placement of the unit in a horizontal position with the index arrow pointing down

• UL recognized as an industrial motor controller per UL standard 508, suitable for mounting in a protected environment

APPLICATIONS

• Environmental control

• Waste water

• Scrubber systems

• Holding tanks

• Cooling towers

• Chemical/petroleum processing

• Plating and washing tanks

• Sewage treatment

• Car washes

• Remediation systems

• Thermal storage systems

• HVAC and building automation systems
