Apex Flow Rate Alarm

[Adalius]

Hey gang,
I have a flow meter set up on my ATO line and I want it to alert me if it runs over a certain rate for a certain time. Like if it's dumping 4 GPM for more than 5 minutes...

The programming for the input itself allows me to turn on an alarm if the flow rate is above (or below) certain values, but does not allow for a time component and has no advanced programming.

Based on that, I presume what I need to do is make a virtual outlet that does something like:
Set Off
Fallback Off
If ATOFlw > 3 Then On
Defer 5:00 Then On

Then in my email alarm do something like:
If VATOOut On Then On

Is that the right way to go about this?

That's correct. That will alert you if the flow rate has been over 3 for 5 minutes continuously.

You can omit the Fallback statement, they are meaningless with VOs.

Correct syntax for the alarm statement would be: If Output VATOOut = ON Then ON

That’s clever, hadn’t occurred to me to use the defer statement as a form of countdown.
