3.5.7 The Totalizer #1 Menu
Use the Totalizer Menu to configure and monitor the totalizer. The totalizer maximum count is 999,999,999 at which
point it will roll over to 0. 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 101 on page 84 . This example shows how to set the totalizer to
track mass flow in kg/sec.
