CROSS CONTAMINATION CONTROL SYSTEMS WITH FLUID PRODUCT ID SENSORS

摘要

A crossover protection system (10) including a product transport vehicle (15) having a tank compartment (25) for containing a liquid product, a fluid property sensor (130) positioned to contact liquid product stored in the tank compartment (25), a system controller (70), and a valve (45) coupled to the tank compartment (25). The valve (45)regulates a flow of liquid product from the tank compartment (25) and has a normally locked state. The system controller (70) may compare a received transported liquid type signal from the fuel property sensor (130) indicative of the type of liquid product in the tank compartment (25) and compare the type of liquid product to a stored liquid product type. If the two types match, the crossover protection controller (70) transitions the valve (45) to an unlocked state to allow the liquid product to unload from the tank compartment (25). If the two types do not match, the crossover protection controller (70) will disable the valve (45) from transitioning to the unlocked state.
