I did have to reverse a few things. but here is final flow
This is all your handy work @jbudd
Thanks

off topic a bit; How did you read the ADS1115? what nodes do you use?

[9toejack]

Do you need for pressure or for volume?

[9toejack]

here is my flow, top just covers psi
lower is how I calculate volume, however i had to "//" some lines because of issues.
and i have a weird thing going on with one of my sensors reading incorrectly by 50 percent.
so I had to make an adjustment.
