Re: Erratic Aquastream

Quoted from "Mr_modnaR"
Hi all, my aquastream, although being set at 74Hz, keeps intermittently dropping in speed. the flow drops from about 60l/hour to 48l/hour
has anyone else experienced this?
is it normal?
Doesn't sound normal to me. Do you have power going to both the Aquaero and the Aquastream controller? What kind of PSU do you have? Have you checked the voltage going to the pump? It should read 9 volts ac. Any warning lights from the controller?
Also 60 liters per hour isn't a lot of flow. A Koolance Exos gets better flow than that! Are you using the AC flowmeter?

What kind of PSU do you have?
Antec Truepower 2.0 430W
Any warning lights from the controller?
:-/ Can't tell, it's installed in my case attached to my aquaero!
Are you using the AC flowmeter?
Yes. was deliberating on whether or not to do the mod to it to improve flow.
By the way, the one aquastream is pushing coolant through:
Cuplex XT
Twinplex
AquagrATIx (9800)
Airplex EVO 160 x 2
Aquadrive dual
Flow Sensor (unmodded)
Aquatube
Hands up who thinks that's too much for it?

No no no ..
fairytales in our forum. Brothers Grimm is a nice movie.
First of all .. you need at least 20 l/h flow. If you have 48 l/h then let it be 48. You won´t recognize any temperature difference at all and the pump is much more quiet.

The pump speed breaks down because your PSU is not stable enough on the 12 V. The aquastream is quite sensible on this. So if the voltage rises or drops it will go down to standard frequenz for safety reasons.
That´s all.
