Tank Monitor 200 Three Tank KitFluid level monitoring system for plastic holding tanksThe LevelGuard Tank Monitor 200 provides accurate, early warning for critical holding tank fluid levels. With digital certainty, the LevelGuard Tank Monitor 200 is the reliable choice for monitoring fluid levels in 2, 3, or 4 tanks. This tank monitoring system is suitable for any applications that carry water-based solution: industrial or farm liquids, bulk beverage or dairy, fresh or waste water, sewage, ground water, coolants, pesticides or fertilizers.Features: Three sensors per tank with an LED display panel lights shine progressively when sensors detect liquid at each level: Empty, 1/3, 2/3, and FullDisplay includes fresh water, holding tank 1, holding tank 2 indicators (depending on model selected)Tanks can be any volumeNo mechanical float switches or moving parts to jam, fail, or wear outNo exposure to corrosive liquidNo probes to get clogged or coatedEasy installationNo tank intrusion requiredSensors attach to exterior of tank with aggressive adhesive (unaffected by moisture or vibration)1-year warranty How it works:Field-Effect sensors (encased in rugged plastic) create an invisible, low-power electric field that detects fluid levels. When a conductive material, like water, enters the LevelGuard "e-field", the sensors detect its presence and trigger the alarm. Tested to millions of cycles in fluid control applications, LevelGuard  performs reliably under extreme conditions of temperature, humidity, UV, vibration and salt water corrosion and is a robust solution for challenging environments. Specifications:Voltage rating: 10.5 to 14.4 VDCEach sensor draws 16 µA when no key pressed; 2.5 mA activatedCan connect to an indicator panel, audio buzzer or relay to remote signaling deviceNo damage if wired with reverse polarityCAUTION: Note for use with metal tanks. Can be used with fiberglass tanks if surface is smoothed so sensors have full contactKit Contents:LevelGuard Tank Monitor display panel with LEDs and 6" (152 mm) color-coded wire leadsWiring harness with 3 daisy-chained "field effect" sensors for two, three, or four tanks and 12" (305 mm) color-coded wire leadsFuse holder
