SURESITE® LEVEL INDICATORS SureSite® Visual Liquid Level Indicators ...the safe alternative to cloudy, breakable sight glasses. High Visibility­ Brilliantly colored flags are easy to read, even at great — distances. The indicator is isolated from the measured media; therefore, SureSite Indicators can be used where sight glasses are not even a consideration. Durability—Stainless steel, PVC, CPVC, PVDF, Hastelloy or other exotic housings, whatever the media requirements, provide years of maintenance-free service. Environmentally Safe—Monitored liquid is contained inside a pressuretight housing. Engineered Plastic Efficient—Continuous level indication without external power. LEVEL INDICATORS – VISUAL Electronic Control—Attach optional point level switches and/or continuous level transmitters to extend capabilities beyond those of a simple sight glass. Low Maintenance—No glass to break, durable housings OSHA Friendly—Accident incidence reduction Reduced Workload—Quick and easy viewing shortens monitoring chores EPA Friendly—Fewer seals and no glass protect against spillage Multi-Purpose—Not single purpose as with sightglasses; can replace simple tank gauging systems as a complete level gauge package When Gems Sensors & Controls introduced SureSite® Liquid Level Indicators almost 30 years ago, no one had seen anything like them... sightglasses were the standard in liquid level indication.
