Current draw can easily be measured, with the right meter.
So if I have an Eheim 1250, pushing 100 gph, which, according to the p/q curve results in a pressure drop of 1.7 meters (2.42 psi), and let's say that I (theoretically) measure the current draw at 0.20 amps, for an AC voltage of 117, which translates in a power consumption of 23.4 Watts.
Where can I go with these numbers?
