Example:
Maximum flow rate = 600 gallons per minute
(600 gallons per minute = 10 gallons per second)
If unit per pulse is set to 600 gallons per pulse,
the totalizer will pulse once every minute.
If unit per pulse is set to 10 gallons per pulse,
the totalizer will pulse once every second.
Energy
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.
