Water/ well flow meter.

Hey, Looking to start offering well flow testing. Looking to find a decent quality well flow meter and also a water flow meter that hooks up to a sink faucet. If anyone has any suggestions/ recommendations I would greatly appreciate it.

Another discussion going on.

Well flow testing is much more than simply putting a gauge on a hose bib. In hundreds of well tests, I have never used a meter on an interior faucet. Most kitchen and bath faucets nowadays are flow restricted anyway so what would be the reason?
