Folks,
I need your help, I'd like to create a tag to be used as calculation accumulative reading of my flow meter. my meter is daily reset @ 6 am. I don't want this tag to be reset

Assuming you can read the live flowrate, the totalizer tag is what I've used for this - link below:

Thanks TomE for your answer, actually we already using totalizer to calculate daily flowrate. and the totalizer is resetting @ 6 am every day, I'd like to add this daily flowrate and calculate the accumulative flow rate on yearly basis

can you use another totalizer tag that does not reset, or a History Statisitcs Tag if the daily total is only logged at the point of being reset?
