Chapter 3 Operation Series 24-HP Instruction Manual
3-8 IM-24-HP
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.
Example for Setting the Totalizer
