METHOD FOR MEASURING FLOW OF WATER PURIFIER

摘要

PURPOSE: Provided is a method for measuring flow of a water purifier which is able to accurately measure the flow by compensating the flow when the water purifier used in an area where the flow is able to be measured by using a flow sensor is possible but the accuracy is a little bit short. CONSTITUTION: The method comprises steps of (a) after comparing a pulse number per second from a flow sensor with a determined flow compensation reference value, determining it as a normal measurement mode when the pulse number per second is more than the flow compensation reference value and setting-up a flow measurement pulse only by the pulse generated from the flow sensor; (b) determining it as an error area when the pulse number per second is less than the flow compensation reference value and operating an error area timer; (c) adding a pre-determined compensation pulse number presently measured pulse corresponding to the counted time by the error area timer to the pulse number per second; and (d) switching off the error area timer when the pulse number per second is not more than the minimum movement flow of the flow sensor and adding the flow compensation pulse to the flow measurement pulse to calculate the total measured pulse for determining the filter replace time.
