Someone from A-C will probably have to answer the question about the Control-O-Matic as I know nothing about it.

The Aquaero info I have shows that the software will allow you to adjust the calibration for different manufacturer's of flow devices. So I suppose that you probably can hook it up providing that the connectors are the same or you modify them yourself.

The calibration factor intrigued me as I have been concerned about reported flow reduction in the A-C unit. I figure if I check the flow with the standard A-C unit and then bore open the holes through the unit as possible I then can recheck the same flow reading and adjust the calibration factor so it reads the same as before with less flow restriction ;D
