Hey everyone,

Implementing a totalizer in a VTScada application at a wastewater treatment plant (no pulse output on the flow meter unfortunately) and I'm wondering if there's any way to initialize the totalizer with an initial offset as the onboard totalizer on the flow meter will have accumulated a flow total as it's been running for a couple weeks now. Worst case scenario, I could record the current total and reset the total in the meter and hopefully they would more or less agree with each other as time goes on (I'm aware that a certain degree of error will be present when using a totalizer on an analog signal), but it'd be nice if I could get it set up with the current flow meter total when I add the totalizer to the application.

Thanks in advance!

Make a couple of IO and Calc tags (one memory and the other calculation), use the memery one to store/configure the offset and the calculation tag to sum the totalizer and the offset. Use the calculation tag as your display etc.

That was kind of what I was leaning towards but would need to do some stickhandling so that if they reset the application totalizer that it didn't still have the offset, which shouldn't be hard.
