ABSTRACT:
A device for automatic dilution of chemical additives and water utilizing a single pump (20) drawing water and other chemical additives through a dilution manifold (10). The introduction of air into the system is monitored such that the system performance is not impaired. If the air leak is small corrections can be made or the system will accept the small error, but if the air leak is large, the system will shut down and activate an indication or alarm to signify that some malfunction has occurred, such as a chemical supply being unconnected or empty.
