Cross contamination control systems with fluid product ID sensors

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 into the tank compartment and having a normally locked state;
• a fluid property sensor positioned to contact the liquid product stored in the tank compartment;
• and
• a system controller communicatively coupled to the valve and the fluid property sensor, 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 a loaded liquid type;
• receive a transported fluid property signal from the fluid property sensor, the transported fluid property signal being indicative of at least one of a viscosity, density, dielectric constant, and temperature of the liquid product in the tank compartment;
• determine a transported liquid type of the liquid product in the tank compartment based on the transported fluid property signal;
• compare the transported liquid type to the loaded liquid type;
• maintain the valve in the normally locked state or transition the valve from the unlocked state to the locked state when the loaded liquid type and the transported liquid type do not match to prevent the flow of liquid product into the tank compartment;
• and
• transition the valve from the normally locked state to an unlocked state or maintain the valve in the unlocked state when the loaded liquid type and the transported liquid type match, thereby permitting the flow of liquid product into the tank compartment.

A method for preventing the mixing of dissimilar liquid products, comprising:

• coupling a tank delivery connector to a distribution side of a valve coupled to a tank compartment of a product transport vehicle;
• interrogating a tank tag coupled to a distribution tank with a tank tag reader to retrieve a stored liquid type encoded on the tank tag, wherein the stored liquid type is indicative of a type of liquid product stored in the distribution tank;
• transmitting to the system controller a tank delivery connector ID signal indicative of an identity of the tank delivery connector;
• pairing the tank delivery connector to the system controller;
• transmitting to a system controller the stored liquid type signal indicative of the stored liquid type of the distribution tank;
• receiving at the system controller the stored liquid type signal;
• determining the stored liquid type based on the stored liquid type signal;
• comparing the transported liquid type to the stored liquid type;
• maintaining the valve in a 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
• transitioning 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.
