This external tank monitor system delivers precise level readings within one quarter inch, letting you know exactly how full your holding tanks are. Senders adhere to the exterior of plastic or polyethylene tanks, avoiding the sewage buildup that occurs with internal probes. The stackable or cuttable design adapts to various tank configurations.
