Totalizer Operation
Overview
The meter provides a display of accumulated flow total by integrating the flow
rate input to the meter and multiplying this value by a user-defined totalizer
conversion factor. The total is displayed on a six-digit display that is capable of
reading to 999,999. When the total exceeds 999,999, the display “rolls” over and
begins counting from zero again without loosing counts. The total can be reset at
any time via the front panel, via an external switch closure, or when the meter
reaches the highest preset value.
