Power vs Current Monitoring
Power vs Current Monitoring
(OP)
Our electrical engineer and electrical technician swear by current over power monitoring for our AC mag drive pumps.
The API standard states to use power. I think power is a lot more understandable to operators. Is there a reason to prefer current besides cost?

So it depends on why / what you want to monitor power (or current).
RE: Power vs Current Monitoring
Because most pumps tend to operate at or to the left of BEP and most motors are sized to cover the entire flow range without going into safety factor, many motors routinely operate at well below the nameplate power in that relatively flat amperage range. In contrast, power tends to be much more linear over the entire range which allows for much better control. It also makes diagnosing pump issues much easier if you're looking directly at hp/kw as you can look at your performance curve to see where you are operating on the curve.
