DETERMINATION METHOD OF UNACCOUNTABLE WATER VOLUME Russian patent published in 2009 - IPC G01F1/00 G01F15/75 

FIELD: physics.

SUBSTANCE: invention can be used to determine water volume (V_CE) unaccountable by correct measurement instruments (MI) during contingency events. By recording methods of contingency events MI are divided into groups. MI with uptime metre are referred to one group; the other group includes MI forming archives of volumes, contingencies, type and duration of contingency events. For one group of MI V_CE=q_{HOURLY AVERAGE}·t_CE,

where q_{HOURLY AVERAGE} is hourly average consumption in previous billing month with consideration of facility operation mode, t_CE is duration of a contingency event. For MI of the other group

V_CE=q_AVERAGE·t_CE, where q_AVERAGE is calculated depending on duration of a contingency event (t_CE).

EFFECT: invention provides increase in accuracy measurement of water volume unaccounted by MI during contingency events at least during operation of one production facility without interruption of intended MI application.
