I'm looking for a very low-flow (drip rate) flow meter thats cheap! It will be for monitoring kalkwasser (limewater) that will be dripped into a sump. Requires a 0-5v dc output of the flow, in-line, and cheap. Accuracy is not important as it will only validate a visually inspected drip rate.

 

How about a rain gauge!

Thanks for the reply Phil, however, it need to be "in-line" as the limewater cannot (or at least should not) be exposed to air before entering the sump. I know there has to be an easy solution to this as there are models that if you could somehow get without the digital display would be in my price range (about $50).
