Abstract: A system and associated methods for monitoring fluid distribution for heavy duty vehicles are provided. The system preferably includes a first handheld radio frequency (“RF”) data communications terminal having a portable housing readily adapted to be positioned in the hand of a heavy duty vehicle driver and a first RF transceiver connected to the portable housing to collect data from customer fluid delivery locations. The system also preferably includes at least one heavy duty fluid transport vehicle and a vehicle data communications terminal mounted to the at least one heavy duty vehicle having a second EF transceiver. The system additionally preferably includes at least one fluid storage tank positioned at a customer fluid delivery location for receiving and storing fluid transported by the heavy duty vehicle having a tank identifier for identifying the tank and adapted to be received by the data collection device of the first data communications terminal.

Abstract: A system and associated methods for monitoring fluid distribution for heavy duty vehicles are provided. The system advantageously includes a first handheld RF data communications terminal. The handheld data terminal preferably includes a portable housing readily adapted to be positioned in the hand of a driver of a heavy duty vehicle and a first RF transceiver connected to the portable housing for transmitting and receiving RF data communications to thereby interface with a heavy duty vehicle driver to collect data from customer fluid delivery locations. The system also includes at least one heavy duty vehicle adapted to transport fluid and a second vehicle data communications terminal preferably mounted to the at least one heavy duty vehicle. The second data communications terminal preferably includes a second RF transceiver for transmitting and receiving RF data communications.

Abstract: An apparatus and methods are provided for metering explosive fluid. The apparatus preferably has an explosive fluid distribution pipe for distributing explosive fluid and an explosive fluid meter in fluid communication with the explosive fluid delivery pipe. The explosive fluid meter preferably includes a housing and an explosive fluid metering device positioned within the housing for metering explosive fluid. The explosive fluid metering device includes a rotatably mounted shaft rotatable responsive to explosive fluid being distributed from the explosive fluid distribution pipe. An immune data converter is positioned within the housing of the explosive fluid meter and is connected to the rotatably mounted shaft for converting the rotation of the shaft into optical data communication.
