Measuring GPH

[NoxAeternus]

Hello,

Just a quick question, does anyone know if there are any instruments for measuring flow (in gallons per hour)?

If not, how does one tweak the flow in the plumbing of one's setup.

there is a good flow calculator on this site. it takes into account plumbing and head loss etc. As for actual measuring tools, I don't know.

Also found one, realized it was called a 'flowmeter'...
