Low Cost Water Flow Sensor

[SimonHa]

Simon - i think thats just a visual indicator - i cant see any pulse output. I had something similar but less attractive on my old water cooled PC rig.

Looking again, you're right - there are no cables - WTF! I suppose at least you can see if the cooling has packed up and your processor is going to melt, but it's not really my definition of "meter". A lucky escape though!

not cheap but has a pulse output for £57 plus VAT or so..... just about to buy some for an industrial project along with a display (£112 pls vat - OUCH)

should be reliable and long lasting

http://www.seeedstudio.com/depot/g12-water-flow-sensor-p-635.html will ship by post for $3.60 for the first sensor and about $0.67 for each extra one (up to 6 when it's free shipping). So that would be $13.40 or about £9 delivered 

Delivery takes 10-30 days but whether it's 10-30 days in transit or 10-30 days sitting on my desk is a bit academic!

Does anyone else want to buy one of these at the same time & we'd just split the cost equally?

I think I'll probably order one of these later today so if anyone else is interested please send me a PM ASAP.

StB: thanks v much for the offer, I might take you up on that once it arrives.
