3.3.6 The Totalizer #1 Menu
Use the Totalizer Menu to configure and monitor the totalizer. The totalizer output is a 50 millisecond (.05 second)
positive pulse (relay closed for 50 milliseconds). The totalizer cannot operate faster than one pulse every
100 millisecond (.1 second). A good rule to follow is to set the unit per pulse value equal to the maximum flow in the
same units per second. This will limit the pulse to no faster than one pulse every second.
As an example of how to set an output, refer to Figure 58 on page 61 . This example shows how to set the totalizer to
track mass flow in kg/sec.
