Flow Rate Meters

merksdave · 09-30-2002, 07:19 PM

Hi, I am about to setup my watercooling kit, but would really like a flow meter. Does anyone know where to get one? Electronic ones like the innovatek would be great, but jst a fan spinning would be okay to. Thanks

Any info on cheap stuff post it!

thanks

Dave

I bought a Lake Monitors electronic water flow sensor on ebay but I haven't looked into getting it to work yet. I remember seeing a spinning thing on a reseller website but there's to many for me to go randomly searching through now.

At FrozenCPU they have flowmeters.. kinda pricey though. Look under their "Watercooling" section.

If you have some free time, build one! It's easy enough, all you need is a drill, epoxy, barbs, suitable case and broken fan.

Do you mean a flow indicator, rather than a flow metre?...

I believe RS make one in 1/2 & 3/8inch sizes. I'll look for a link...HERE!!:

Here's a link to a forum were the dudes making an autoshutdown from one of these electrical flow sensors:

Thanks MadDog, that's a great link!!!

I tried finding the specific sensors on RS (cause the link died) and there were so many of them!, most were industrial and useless, but there was a visual one abit like the Inovatech 'Flowmatic' but 1/2 inch that looked very nice called the 'Rotorflow!!'

.
This is my favorite though:

I found a couple of useful ones on that site; a cool-ass flow indicator...

(the metal bits are sold seperately and some accomodate 1/2" connections)

... and two flow sensors. This one

operates on 5V and senses upto 20 l/min flow (a 300 GPH pump produces 18 l/min). It emits 750 pulses per litre flow; at 18 l/min that is 13500 pulses per minute; similar to a (admittedly very fast) CPU fan. Connections are 3/8".

This one

has 1/2" connections, runs on anything between 4.5V and 24V, and emits 23 pulses per second at 12 l/min flow. At the aforementioned 300 GPH (18 l/min.) that is 2175 pulses per minute, i.e. similar to a somewhat slow CPU fan.

I made a Flow METER out of an old case fan, some neoprene foam & some plexi. At normal flowrate it outputs about 1v.

This is a non-speed sensing Adda fan - water spinning it turns it into a generator.

Here's an inexpensive one: http://www.drsfostersmith.com/produc...=6&pCatId=4532 .

I don't know anything about it, just saw it when looking for pumps.

Hmm, I need to work on a home-built electronic flow indicator...
