Hello all.

I know this almost a repeat question but I don’t think we really arrived at the answer. https://archive.knowledgepoint.org/en/questions/3011/does-anyone-have-any-experience-in-measuring-the-flow-of-hand-pumps/

I am interested in metering hand pumps for monitoring and evaluation (not for payments). I am aware of the exciting new developments in remote meters (smart hand pumps (oxford), sweet lab, welldone and charity:water).

I was wondering if anyone has had success with cheap, commercially available meters linked up with some sort of mobile/cell phone system (mWater, see/saw, AKVO).

The example of a domestic metered hand pump indicated that meters failed after one month https://www.uwasnet.org/Elgg/file/download/6474

The meter should be able to: deal with turbid water, operate without mains electricity, and handle low flow rates and profiles (half filled pipes, air pockets) associated with hand pumps in our areas.

It seems like the only meters built to deal with turbid water are agricultural which cannot pick up low flow rates.

Finally, the meters need to be cheap.

Thanks so much for your time!

All the best, Orlando
