Model L8 Flotect

Liquid Level Switch features a leak proof

body and float constructed from tough, durable polyphenylene sul-

fide (PPS) which has excellent chemical resistance. Because the liq-

uid 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 indus-

trial motor controller per UL standard 508, suitable for mounting in

a protected environment. This lightweight switch can be used in nu-

merous chemical process, industrial systems and similar applica-

tions 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 han-

dle temperatures up to 212°F (100°C) and pressures to 150 psig

(10 bar).
