1. A crossover protection system, comprising:

  • a product transport vehicle comprising a tank compartment for containing a liquid product;

    a valve coupled to the tank compartment, the valve regulating a flow of liquid product from the tank compartment and having a normally locked state;

    a tank delivery connector fluidly coupled to a distribution side of the valve;

    a tank tag reader for interrogating a tank tag coupled to a distribution tank separate from the product transport vehicle, wherein the tank tag reader;

    interrogates the tank tag to retrieve a stored liquid type encoded on the tank tag, wherein the stored liquid type is indicative of a type of the liquid product in the distribution tank; and

    transmits a stored liquid type signal indicative of the stored liquid type and a tank delivery connector ID signal indicative of an identity of the tank delivery connector; and

    a system controller communicatively coupled to the valve and the tank tag reader, the system controller comprising a processor and a storage medium containing computer readable and executable instructions which, when executed by the processor, cause the system controller to automatically;

    receive the tank delivery connector ID signal from the tank tag reader;

    pair the tank delivery connector having the tank delivery connector ID to the system controller;

    receive the stored liquid type signal;

    determine the stored liquid type based on the stored liquid type signal;

    compare a transported liquid type to the stored liquid type;

    maintain the valve in the normally locked state when the stored liquid type and the transported liquid type do not match to prevent the flow of liquid product from the tank compartment; and

    transition the valve from the normally locked state to an unlocked state when the stored liquid type and the transported liquid type match, thereby permitting the flow of liquid product from the tank compartment.
