MNF Method of Error Compensating for Measuring the Minimum Night Flow in Water Distribution Area

摘要

The present invention relates to a method for correcting a small block MNF (Minimum Night Flow) measurement error using a middle block flow rate of a water supply pipe area of a water supply pipe in a water supply network, wherein the block is blocked in a plurality of small blocks and includes a water level meter A block information DB, a correction information DB, and a measurement information DB in a block water pipe network among the reservoir areas including a small block flow meter at a block entrance point of each of the plurality of small blocks, A method for compensating for a minimum block flow (MNF) measurement error in a small block MNF using a block flow rate of a water network, wherein the water level meter measures a water level at a reservoir level with the reservoir inlet closed during a time zone including a middle block MNF time zone And the block information DB stores each small block flow meter type information for all of the plurality of small blocks And the correction information DB includes a correction coefficient according to the type of the small block flowmeter, and the measurement data DB measures and transmits the measurement data to the drainage level meter and the small block flowmeter. Are recorded.
