Which AC Flow Meter Should I Choose for My Aquaero 5 Pro?

post #1 of 11
Thread Starter 
Hello everyone,

I am wanting to purchase an Aqua Computer flow meter/sensor for my Aquaero 5 Pro but am having trouble choosing which one is the best, there's the brand new Flow Sensor MPS Flow 400 ($67.99) and the older updated Aquacomputer G1/4 Flow Meter Sensor Block USB Version ($79.99). My thinks more expensive one = better sensor, is this one of those cases and how good are the new MPS versus the new one?

I'll try to Answer as best as I can, Until Shoggy or someone else gives a better discription smile.gif..

Most of this comes from HERE

The mps flow series are technically based on a differential pressure measurement and do not contain any rotating components. This method is known from large sensors in an industrial environment, they also cost a fortune and nobody would use something like that for a PC water cooling - until now ;-)

The case is made from Delrin and has an engraved stainless steel cover. The pressure sensor itself is a silicon chip covered by a stainless steel diaphragm. The sensor has a very high resolution of 0.00005 bar. Inside the case we also have another sensor to measure the water temperature. A second temperature sensor can be connected externally. Another connector generates a configurable tacho signal.

While the older sensors use a calibration value (impulses per liter), This one uses a calibration curve. Curves for the most common cooling liquids are already integrated in the software but you can also generate your own curve by adding at least three points with a reference value. The rest is calculated by the software.

While the older G¼" High Flow sensors use an calibration value (impulses per liter), the old mechanical style Sensors have Mechanical "Impellers" spinning, These sensors are also available in a new variant so it offers USB, aquabus, temperature sensors and an tacho signal output..

So, Basically The MPS Sensor has an Electronic Flow Sensor & are restricted to the amount of flow you have for each different units, 100,200 & 400 & the G¼" High Flow Sensor uses a Mechanical Flow Sensor & one unit will monitor a wider flow rate from just the one unit,.. Hope That helps some smile.gif

The number indicates the maximum flow rate which can be measured with the sensor. So the mps 400 variant is only interesting for systems with a pretty high flow rate. I guess in most systems the mps 200 variant is fine.

mps flow 100: measures from 20 - 100 l/h
mps flow 200: measures from 40 - 200 l/h
mps flow 400: measures from 80 - 400 l/h

System flow rate meters.IMHO just a place for data junkies to throw some cash.You can design a perfect loop that performs perfect and keep 80.00 in your pocket.If your thing is making a test station and writing reviews then by all means load up on any and all the types of measuring devices you can think of.

200 l/h is (.88 GPM) below the recommended 1 GPM, the 400 (.36 - 1.76 GPM) would be ideal, right?

I'm at a point now where I either get a flow meter or just buy a second D5 pump and run them in serial, is one D5 pump on setting #5 enough for a EK Supremacy, EK full motherboard blocks and two GPU blocks?

Well, this just brings us to the traditional conflict between European and American watercooled systems biggrin.gif

I think we do not have to focus on this, so if you require 200 l/h as minimum you will have to use mps flow 400 variant.

Let's say my flow rate is 1.5 GPM, the flow 200 variant will not measure flow rates above .88 GPM therefore I won't be able to know what my flow rate is past .88 GPM. Why would I want that?

I got the "High Flow" sensor for about $46 from Aquatuning, it's showing I have 1.3 gpm through the loop with a single MCP35x. I have no idea how accurate that is. In the end it's just an indicator of flow whether it's accurate or not since I have no idea how/why you would control the system based on flow rate.
I was just starting to dig into Aquasuite when I had to replace the motherboard so I'm basically new to all the controlling aspects with the AQ5.

Because I used the wrong number doh.gif
