    Question Alert only when PMUP is running

    I recently had a problem where my ATK PMUP failed to pump water for a long period of time and I didn't notice. I only noticed when I saw micro bubbles in the tank from the water being too low in my sump. Turns out the PMUP needed to be cleaned. I have a 1/4" sensor inline with my PMUP so I can monitor how much water is being topped off into my tank over time. To prevent this from happening in the future, I'd like to receive an alert if there is little to no flow when my PMUP is on and only when it's on. I'm just not sure how to go about this. I suspect I might need a virtual outlet but that's where things get gray for me.

    Any ideas how to accomplish this?

    Thanks!

    Update: I think I may have figured it out - I may have been overthinking. Would this work in my Email code?

    If ATO < 0 When ATO_PMUP ON Then On

    No you need a virtual outlet to do "AND" logic. Replace X with 30-50% of normal flowrate

    PMUPfail
    Set OFF
    If ATO_PMUP = ON Then ON
    If ATO > X Then OFF
    Defer 000:20 Then ON

    Email
    (Existing code)
    If Outlet PMUPfail = ON Then ON

    You might be an engineer if...You have no life and can prove it mathematically.

    Thanks zombie. I have changed my code. The PMUP actually failed again after I cleaned it the first time so hopefully this code will help me know next time.

    Does this code only work because of the 1/4" inline flow sensor? If I don't have an inline flow sensor I can't use this code correct?

    If you don't have a flow sensor, there would be no way for this code to work.

    Thats what I assumed, but I had my fingers crossed hoping the apex could tell when the PMUP was using 30-50% less power instead on water flow.

    Thanks for the quick response
