I've just begun testing of a new type rotary pump and I'd like to get input
if possible from the group on methods.

I can easily measure intake vacuum level, which should give me an idea of
volumetric efficiency.  Would it be valid to use the difference in amp draw
on my electric motor drive to determine what my HP usage is?

Thanks in advance for any comments.

Yes but you need to know the efficiency for the motor. Most motors are around 80%
