Hey guys,
Got another hopefully quick question. I posted a question earlier about measuring the opaquness of water. It had to do with a fume scrubber. This is related to the fume scrubber, not the opaquness measurment. The project manager/engineer want to measure the power consumed by the blower fan. She wants to correlate it to blower's HP vs. CFM curve to determine the amount of air flow going out the stack. I suggested a power monitor, but another person person said to just bring in one phase of the motor's current, and multiply it by a value of 120 to determine the power. He said the voltage should be pretty constant. I disagree. You have to take the pwoer factor into consideration dont you?? Thats what a power monitor will do?? Correct?? Thats at least what I remember from my power systems classes. If you dont take the power factor into consideration, you will have an error in the readings, because you arent measruing "useful" power, you would be measuring reactive power right?? I would love to hear your opinions and comments, am I out to lunch?? How would you guys do this??
Thanks
