control-NumericTotalizerExt

NumericTotalizerExt is a control point extension used for integrating a numeric point value over time. For example, a totalizer with a minutely totalization interval can convert an instantaneous flow reading in cubic feet per minute (cfm) into a value representing total cubic feet consumed. An available resetTotal action clears (zeroes) any accumulated total.

The NumericTotalizerExt is available in the Extensions folder of the control palette.
