Flow metering apparatus for block supervisor system

A flow metering apparatus for a block system is provided to prevent loss of flow meter data at the time of a power failure or communication interruption by securing stable data management and transmission. A flow metering apparatus for a block system comprises a flow meter selection switch(32), a data memory(24), a program storage unit(26) and a controller(22). The flow meter selection switch is equipped so as to select a data structure processing program corresponding to a flow meter type. The data memory stores flow meter data measured by a flow meter(12) and transmitted to a managing server together with time information. The program storage unit maps the data structure processing program and a motion program corresponding to the flow meter type. The controller transmits inverted flow meter data to the managing server and stores time information and the inverted flow meter data in the data memory.
