It watches the fluid levels in up to six compartments and triggers an alert or shut-off to prevent overfilling at the loading rack, and also retains signal when you need bottom-service control. You replace or retrofit this monitor when your current overfill system fails diagnostics, won't program, or you're upgrading to a unit that works with all sensor types (optic, thermistor, or float) without needing terminators.
