The Aquaero is wrong, and thats not saying anything bad about it, it does a lot of functions and does them well, but you cant have everything in 1 setup. If it comes down to Aquaero vs multi meter for current results I am trusting the MM.

true about a multimeter this is for sure and did not say that the motors had changed but I do know that the motors do not have to change for them to be more efficient better pumps can do this. Also how do you get a wattage measurement using a multi-meter??

Take the leads on your multi and touch them to the respective pins, best to use needle pins with a fan lead. Red to 12v and black to ground just like you would anything else, that would be the easy way smile.gif it would be better to test at the board but that would be a little harder to do.

And just so no one gets offended I am not dissing the AQ6 by its readings being off, there is a lot of tech in that little thing its hard to do everything perfect. Its most likely more accurate than motherboards smile.gif.

This is for testing a bad fan but it gives you an idea how to do it smile.gif https://www.youtube.com/watch?v=CmYE5Qtda2k

You could also build a custom 4 extension wire that hooks directly to a MM, this would make it easier for constant testing and a little easier with like an AQ.

sorry but that will not work to get a wattage reading you can get a voltage reading like this but not a wattage reading.. I have ran 2 DDC PMW pumps and measure it using the correct meters and it will really surprise you what you will get for a total wattage. I do not have access to the filers I saved on this but it was 30 watts give or take a watt or so.. and want to say lower but memory is something I lost with age..

not offending me at all just want to make sure everyone gets and has right info..

Awesome be sure to let us know thumb.gif. I am curious if seross is right and something has changed, it is possible smile.gif.

need more than a flute multimeter as power or wattage is volts X current

you will actually need a clamp on amp probe and a multimeter

Not if he is just trying to get the full speed, if he wanted to test the wattage at different PWM ranges then yes he would need an oscilloscope. The fluke can give him the Current and the Voltage and he can do the calculation.

Which actually brings up another issue with AQ6s readings, PWM current is not easy to measure and to get a true measure you need a oscilloscope. Which is a very large very expensive device needless to say the AQ6 doesn't have that functionality, so its PWM readings are most likely a bad judge all together, (full speed aside). However there again its claiming 11v, I could be wrong but should it be 12v at all times? and varying pulses of 12vs to control the PWM. If you have a leads of some kind you should compare the AQ reading with a direct 12v line like a molex.

If you have a leads of some kind you should compare the AQ reading with a direct 12v line like a molex.

a True RMS amp probe and multimeter is going to give you the best measurements to get wattage from. because they take the root mean square of the signals. You could get the amp reading with a O-scope but I would be real hesitant to put that kind of potential through a 0-scope some are rated for 1 or more amps but most are just for milliamps.

all you measure is the pulse width of the signal the PMW does not carry current it just turns on the motor for a time depending on the width of the pulse or turns it off. you will measure voltage from GND to +12 and will measure the current either on the + signal or sometimes the ground is the current carrying line.

You can get a O-scope that uses USB that will fit in your pocket for under 100 dollars that will measure the PMW signal and show it to you..

you have to have currant and voltage to calculate watts, kw or hp and all 3 are the same..

I do these calculations and work on this equipment on a much larger scale for a living. I have held several engineering positions on drilling rigs around the world. So I do have a idea what I am talking about.

I would advise against that. A DDC uses 21ws of power so each would needs its own channel. Also not sure how well the wires would hold up to that kind of load, It has a molex connector for a reason. If it was a good idea to run DDCs in that way I would think they would have a version made in that way.
imo a properly cooled aq would have no issues powering 2 pumps, but ill leave that to shoggy to answer

the wires on the other hand are fine, MOST when they do the mod, just reuse the same wires but all you have to do is look at the awg and the length, and a little googling and you will find the amps are fine for that wire size ( iirc 22ga but i may be wrong as i am going off the top of my head )

all pump controls are personal pref, vario, pwm, or voltage

pwm does have the adv of more power at lower rpms, iirc

and vario doesnt take up any channels

i want to add that motors ONLY use as much energy as needed. it is rated at a MAX current ( may or may not include starting currents ) but a max is not the same as what it DOES pull

the harder the pump has to work the more amps it will pull, so if instead of water ( 100% ) you replace it with a glycol mix you will use more amps to provide the same speed, the motor has to work harder to do the same work, as the glycol mix is thicker then water


which is why the DDC spec sheet from xylem inc laing thermotech the manufacture says the rating is a MAX rating,

Actually if you want to be more specific this is the Max rating passive cooled, change the heat sink or use forced air cooling and the max rating goes up.. we use a lot of GE 752 DC traction motors and the difference between a 900hp, 1050hp or 1500hp rating is the size of the blower that is cooling the motor!!
