ABSTRACT:
A monitoring device for a drinking water purification system comprising a microprocessor that controls the overall operations of the monitoring system, a LCD indicating circuit that relates information to maintenance personnel, a detecting means that analyses related data for determining the condition and extents of clogging of the filtration elements, a warning means that produces verbal or musical sound for warning consumers about the clogged condition of the water filtration elements, and a power switching means that cuts off electricity supply to the water pump of the purification system. In operation, the filtration elements will be clogged by impurities after being used for a period of time. If the filtration elements are clogged, the monitoring device will make a sound to warn of such condition of the filtration elements and will eventually cut off the power supply to the pump for stopping water delivery if the clogged filtration elements are not replaced after a certain period of time.
