Is there anyway to do basic arithmetic in the outlet programming?
Explanation: I have a virtual outlet to set an alarm if the flow in my tank is too high - the tank drains/overflow can only support ~1000gph . I have a 2" flow sensor on the return plumbing to monitor this, however I have water from my return tee'd to two other parts of the system that don't impact the tank flow. These both also have flow sensors on them. So, ultimately I want to set an alarm if: {return flow} - {fuge flow} - {filter flow} > 1000. Unfortunately, I cannot come up with a way to do simple arithmetic with the flow sensors to set up this alarm.
Any ideas or thoughts on this?
