Title:
FLOW RATE MEASURING DEVICE OF BALLAST WATER TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/050133
Kind Code:
A1
Abstract:
The present invention relates to a flow rate measuring device of a ballast water treatment system. The flow rate measuring device includes: water level sensors installed on a plurality of ballast tanks, respectively; and a control unit for calculating a total cumulative flow rate by summing the cumulative flow rates of each of the ballast tanks during a ballasting operation time on the basis of water level information received from each of the water level sensors, and calculating a converted flow rate per time by dividing the total cumulative flow rate by the ballasting operation time. Accordingly, the flow rate measuring device has the effect of enabling stable operation of the ballast water treatment system even when a flowmeter malfunctions or fails.
