MTG redundancy consists of the installation of one or more independent gauges (transmitter cards and sensor arrays) within one physical probe.  Each of the engineered configurations can provide fully redundant gauges or two independent gauges, each with differing applications within the same probe.  Also see Virtual Gauge.

Each gauge has its own transmitter card assembly and sensor array within the shared gauge housing, thus, one (1) tank top flange opening is required for mounting “Two” gauges (with or without a gauge well). Each gauge uses independent signal and power sources within the system to maintain complete independence. No shared components between gauges, e.g., Antenna, power supply, IS barriers, field wiring, communications, etc.
