Hey guys.
I have both the MPS 400 and the MPS 200 flow meters.
In my loop, I plan to have a good flow over 2 GPM (450 L/h).

But my MPS 400 is only rated up to 400 L/h. What happens when the flow goes over the 400 L/h top limit of the MPS 400? Does it keep reading the fliw, just less accurately? Or does it get stuck on the 400 L/h reading?

Is the meter useable above it's rated top limit?

I am planning 4x SLI and so in paralelle, with 0.5 GPM to each card, a total flow of 2 GPM is desired. All the better if I can get more, but not holding my breath for it.

BTW, I am not using the Aquaero, I use the Lamptron line to control and monitor ny loop.

The MPS 400 sensor would need to be plugged to a USB header and software monitored with Aquasuite.

But I run a dual booth Windoze/Linux machine. So Aquasuite is not my prefered method of retrieving flow sensor reading.

The flow sensor you linked to, would it also require Aquasuite? Or could I pkug ut in my Lamptron and read it as an ither RPM reading?

Sorry for the typos. This site makes it difficult for me to correct and edit my posts. Here is what I was asking in my last line:

That flow sensor you linked to, does it report flow as an RPM value? Or would I still need Aquasuite to retrieve my flow reading from the sensor?

Hey Jakusonfire, wassup!
Just to make sure I got you. The following flow meter will work on a non-Aquacomputer controller as an RPM signal, correct?

As for the accuracy, I beleive that flow sensor can be calibrated, no?

Well the shop site description reads "Please take care to input the 169 pulse per liter value".
That lead me to think that you would input that value in the flow sensor, hence why I thought it could be calibrated. But they probably mean to input that value in the controller. Never the less, if the value per pulse can be changed, either in the flow sensor, or in the controller, that leads me to think you can calibrate it by changing the value of pulses per liter.

Now what remains to find out is weither or not I can use it on my Lamptron CW611 controller, or not.
I need 4 of these (don't ask) and so I want to make sure before I buy it, that it can fit.

Yes, this is exactly what I am saying.
You can calibrate the sensor. If you find that it is, for example too fast, you can change the value on your controller from 169 to 175, or any other value that represents more accurately your actual flow.

Now, this calibration capability is probably only possible on the Aquaero, or any controller that allow you to define the pulse per liter value.

I'm not really sure it would work. I could not find any documentation on the sensor itself, but the Aquaero port that you attach it to is providing 5V for it, not 12, as it would for a fan.

I don't think the voltage supplies, or the voltage returned by the rpm signal is relevent. All that really matters to read the fan's rpm is the pulse frequency. Think of it this way. When you voltage regulate a fan, you could be feeding it 12V or any other voltate value below 12V. So the rpm signal will use the voltate feed to return the rpm signal. Now, the mobo, of fan controller doesn't really care if the if the pulses returned are on 12V or 5V. It only counts the pulse rate to determine fan's speed, not pulse strenght, or pulse voltage.

So as long as the sensor has an rpm signal, it 'should' be able to be read by my Lamptron, or by a mobo fan header.

The sensor sends 169 impulses per liter, I don't think it can be changed.

Well, if you have the ability to input the pulse per liter value in your controller, you can certainly calibrate your flow sensor.
Let's say your sensor is innacurate and only sending 150 pulses per liters. You simply change that value in your controller from 169 to 150, and presto, you just calibrated your flow signal.

Unfortunately, the Aquaero is probably the only controller that allows you to calibrate your pulse signal this way.

So basically, you can calibrate you controller to correct an innacurate flow sensor.

Dammit!
