Each of Dixon's FloTech Trailer Identification Modules contain a globally unique identification number used to positively identify the specific tanker.
The internal computer chip for these modules is independently manufactured by a third party in the USA for both Dixon & Scully, therefore between the two major brands there can be no duplication of the globally unique identification numbers.
The unit is mounted within the overfill prevention socket housing on the trailer.
Dixon's module is compatible with and communicates with the Vehicle Identification Prover (VIP) or rack control system.
