MPS 400 flow meter durability

Wednesday, December 28th 2016, 4:39pm

Hi
I have been a huge fan of the MPS 400 flow meter. But can someone tell my why they don't last for more than 6 month's to a year?? My third MPS 400 flow sensor has stopped working. Am I doing something wrong. I went with two of the USB high flow version in my new build but i really hate the rattling noise. So I would love to go back to the MPS400 flow meters, but i lost my faith in the durability of it ?(

I've been hearing that here and there hence why I went with the High Flow sensor. The rattling for me is only audible once I pass the 1.5 GPM threshold since I don't need to go that high. The sweet spot for all liquid loops when it comes to flow is 1.0-1.5 GPMs. I run my large loop at a 1.0 GPM at max for pump audible reasons but temps won't change much regardless if I pump it up a bit.

I've had three of the MPS 400 Flow Sensors fail in a relatively short period of time.

I also have moved to the USB High Flow Sensor in my recent builds, and have not noticed any objectionable noise. But then again, thanks to 24 years in the USMC, my hearing is shot.

It would be great if someone could figure out what and why the problem occurs :?: . The MPS sensor is great when it works. But it's way to expensive if you have buy a new sensor every 6 month to year..

I have used the high flow sensor before but never had that much noise. I'll try to tune my pumps, maybe I can hit the sweet spot :thumbsup:

I got answers from Aqua Computer today regarding the three MPS 400 flowmeters which stopped working. Since I use Mayhems X1 coolant, it is the most likely cause for the sensors to stop working after a while. The reason is that the X1 coolant contains glycerol and membrane inside the sensor can not withstand it.

Nor can your other gear if you're using them colors. Your blocks, rads will stain. I keep my stuff clear for those reasons and the horrors I've seen over the years.

Ordered new coolant and a new MPS 400 flow sensor today. I give it another go to see if it works :whistling:
