This overfill prevention system probe for tanks for transport of liquid fuels comprises a level detector mounted on a support that is fixed on the tank so that the detector is placed in the tank at a maximum permissible filling height. The level detector includes a measuring sensor capable of providing a redundant level measurement.

This overfill prevention system probe for tanks for transport of liquid fuels comprises a level detector mounted on a support that is fixed to the tank so that the detector is placed in the compartment at a maximum permissible filling height. The level detector includes a measuring sensor comprising a set of several electrodes and means for measuring the dielectric permittivity of a fluid present between the electrodes. The probe also comprises means for testing the satisfactory operation of the entire acquisition chain of the dielectric permittivity measurement of the fluid present at the electrodes.

A product delivery system includes a product transport vehicle having at least a plurality of tank compartments, internal valves, control valves, fluid property sensors, temperature sensors, overfill sensors, pressure sensors, a system controller, and a memory module. The product delivery system may be operable to communicatively connect with the loading system at a loading station, a fleet management system, or a cloud system to obtain information, such as the amount of liquid product to be loaded into a tank compartment. The product delivery system may be operable to compare the volumes of the tank compartments with the amounts of liquid product to be loaded at a loading station and maintain the internal valve or control valve in a locked state or transition the internal valve or control valve to an unlocked state based on the comparison. Other comparisons based on liquid type or distribution tank volume can also be made.

A radio frequency identification (RFID) tag positioning system includes a tag holder having a first region with a slot extending from an edge of the first region, and a second region extending from the first region. When an RFID tag having an antenna is disposed in the slot of the tag holder and when the tag holder is adapted to be retained adjacent a filling fixture of a gas tank with the second region adapted to be in contact with the gas tank so that the slot is approximately perpendicular to a longitudinal axis of the gas tank, the RFID tag's antenna is approximately perpendicular to the longitudinal axis of the gas tank.

A tank support system includes a hollow open-top container having a contiguous sidewall region and a bottom region coupled to the sidewall region. A loop antenna is coupled to a portion of the container's sidewall region. A tuning circuit coupled to the loop antenna provides for adjustment of the loop antenna's electrical impedance. A radio frequency identification (RFID) reader is coupled to the tuning circuit.

A trailer-mounted pumping system includes a flatbed trailer having a generally flat deck surface, a pump, a batch controller, and a metering device in electronic communication with the batch controller, wherein the pump is configured to move a liquid from at least one tote supported by the generally flat deck surface to a location off-board the flatbed trailer, and the batch controller is configured to measure a volume of the liquid via the metering device. The pump, the metering device, and/or the batch controller may be disposed beneath the generally flat deck surface.

The present system is directed in one embodiment to a vehicle with a cargo tank or reservoir and a pumping system, comprising a centralized controlled area network (CAN) in operative communication with a programmed computing device, e.g., a programmed logic controller (PLC) that may automate the pumping process output to automatically adjust based on demand and may further enable a pump flow rate that is infinitely adjustable to match output requirements. In other embodiments, the pump speed is no longer dependent upon engine speed or RPM. In other embodiments, the CAN may monitor for vapor at the pump inlet and automatically slow the pump speed until the vapor problem is resolved. Other embodiments may comprise the CAN integrating various vehicle and pumping systems to maximize safety and safety issue annunciations.

An in-tank illumination system and method for a translucent tank with sensors configured to monitor conditions of the tank and material inside. The illumination system includes an illumination source that illuminates the tank interior and is visible outside; and a controller that determines tank conditions based on the sensor readings, and sends control signals to the illumination source. When the controller detects a tank condition, it sends control signals to the source to illuminate the tank to indicate the tank condition. The system can include a bracket connecting the source to the tank interior near the top. The controller and source can be on different vehicles. Different control signals can change colors, blink patterns, and other properties of the source to indicate different tank conditions. The tank conditions can have different priorities to select which to indicate. The severity or duration of tank conditions can also be indicated.

A safety zone system that includes a vehicle and at least one safety cantilevered arm that is operably engaged with the vehicle. The vehicle include a front end, a rear end opposite to the front end, a longitudinal direction that extends from the rear end to the front end, and one or more pairs of wheel assemblies engaged at least at the rear end. The at least one safety cantilevered arm is also moveable between a stored position and an operating position and is a single unit. The movement of the at least one safety cantilevered arm is also performed entirely along an arm axis that is perpendicular to the longitudinal direction of the vehicle. In the operating position, the at least one safety cantilevered arm is positioned at the bottom end of the vehicle and positioned above the one or more pairs of wheel assemblies of the vehicle.

A method for monitoring an amount of a chemical material that includes: providing an at least one portable container; and providing into the at least one portable container a first amount of the chemical material. The method includes operatively associating a sensor with the at least one portable container, the sensor effective to detect a first level of the chemical material in the at least portable container and to generate a first data signal based on the first level. The method includes operating the sensor to detect a change in the amount of the chemical material in the at least one portable container, and thereby to generate a second data signal based on the change. The method includes using a processor in operable communication with the sensor.
