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