Series L8 FLOTECT® Liquid Level Switch
Low Cost, Leak Proof Body, Excellent Chemical Resistance
The Series L8 Flotect® Liquid Level Switch features a leak proof body and float constructed from tough, durable polyphenylene sulfide which has excellent chemical resistance. Because the liquid level snap switch is magnetically actuated, there is no direct mechanical linkage to leak or fail, assuring longer life and decreased maintenance costs. This inexpensive unit is ideal for liquid level alarm, indication or control. Installation is quick and easy - simply install in a horizontal position with the index arrow pointing down.
The L8 Flotect® Liquid Level Control is UL recognized as an industrial motor controller per UL standard 508, suitable for mounting in a protected environment. This lightweight switch can be used in numerous chemical processes, industrial systems and similar applications where process conditions are compatible with polyphenylene sulfide, Ceramic 8 and 316 stainless steel. This liquid level switch provides accurate setpoint control of liquids with specific gravities as low as 0.6. This compact and reliable control is designed to handle temperatures up to 212°F (100°C) and pressures to 150 psig (10 bar).

Questions
- Question
- Why is the minimum specific gravity important on the float level switches?
- Answer
- If a medium has a lower s.g. than the rated minimum for a float, the float will sink through the media and the switch will not operate.
