I have a GPI paddle-wheel type for my test system, but I don't see the need for flowmeters in cooling loops I am actually using. The deltaP measurement I could go for, however

Or simply, I could build a manometer, and use the flowmeter to measure individual components. Whoever said that all I want to measure is the dP through a heatercore?
But I still need a cheap build guide for a manometer. Google time. The pressure gauges are starting to look better.
