Means for adding corrosion inhibitor to an engine cooling system utilizing a corrosion detector in contact with the circulating coolant and which is in an electronic circuit to activate a control valve which controls the feeding of corrosion inhibitor solution from a reservoir that is in selective communication with the coolant system. The corrosion detector may be in the form of a probe that measures solution potential or electrical resistance of a metal wire as it corrodes due to the corrosiveness of the coolant. The corrosion inhibitor reservoir is located either in communication with the line between the radiator and coolant reservoir or in a by-pass line parallel with the radiator.
A control system for the automatic addition of a chemical additive to a solution requiring treatment, comprising a circulating fluid system for the solution requiring treatment, a sensor inserted in the system in contact with the fluid to determine the level of treating chemical therein and issue a signal when the level decreases below a predetermined value, the improvement comprising a closed chemical treating solution reservoir containing solid treating chemical to be dissolved and chemical treating solution, a control valve controlling liquid flow from said fluid system to said reservoir for positive displacement of treating solution from said reservoir to said system and an inlet and an outlet for said reservoir in communication with the circulating fluid system, a solenoid to actuate said valve, and an electric circuit receiving the signal from the sensor and actuating said solenoid.
A control system for the automatic addition of a chemical additive to a solution requiring treatment, comprising a circulating fluid system for the solution requiring treatment wherein the fluid system is the cooling system for an automotive vehicle including a radiator, a fluid pump, and a cooling jacket for the vehicle engine, a sensor inserted in the system in contact with the fluid to determine the level of treating chemical therein and issue a signal when the level decreases below a predetermined value, said treating chemical being a corrosion inhibitor in the circulating coolant, the improvement comprising a chemical treating solution reservoir containing solid treating chemical to be dissolved and chemical treating solution, a control valve controlling liquid flow to said reservoir and an inlet and an outlet for said reservoir in communication with the circulating system, a solenoid to actuate said valve, and an electric circuit receiving the signal from the sensor and actuating said solenoid.
