Tank Monitor 400 KitFluid level monitoring system for plastic holding tanksThe LevelGuard Tank Monitor 400 provides accurate, early warning for critical holding tank fluid levels. With digital certainty, the LevelGuard Tank Monitor 400 is the reliable choice for monitoring fluid levels in 3 fluid tanks and one LPG tank, from one display. 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: System reads the sensors built into standard RV liquid propane gas (LPG) tanks w/ Rochester type electronics gauge or equivalentProgrammed to flash an alert when levels are critical (low for water and LPG, high for holding tanks)Clean, flush-mounted display panel is compact and organizedTouch interface to display tank level readingsLow Display includes: fresh water, holding tank 1, holding tank 2 indicators (depending on model selected)Tanks can be any volumeReads on-demand; very low current drawNo mechanical float switches or moving parts to jam, fail, or wear outNo probes to get clogged or coatedNo tank intrusion requiredSensors attach to exterior of tank with aggressive adhesive (unaffected by moisture or vibration)Easy installation1-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 VDCSensor draws Display panel includes an adjustable potentiomenter to accommodate variation in readings from LPG tanksLevelGuard Tank Monitor 400 can work with two separate display panels via an additional CAT-5 Ethernet cable (purchase panel and cable separately) CAUTION: 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 Tank Monitor interface module for modular connection to sensorsWiring harness with 4 daisy-chained, adhesive-backed  "field effect" sensors and 15" (4.6 meter)  wire leads (can be extended by customer)8-pin CAT-5 Ethernet cable, 20' (6 meters)
