Figure 3.11  Water Item. Flow (in cubic meters) is the only field selectable.

In BEMS, Water Flow is expected to be read from a meter in units of cubic-meters [m3].  The difference between the current reading and the previous reading is calculated and recorded to the database for this time period (every 15 minutes is the default time period). It maybe be necessary to use and Accumulation Tag in WebAccess if you are measuring a rate (like cubic meters per  hour, m3/hr), then use the Accumulation Tag as the input to BEMS.
