Eric had made me an injector and now the great United States postal service has more than likely lost the package after 3 weeks and no signs of it....

re: looking ot buy a flowmeter, what specs will I need?

I'm going to go with a calculated flow, since I'm only going to need it for comparisons it should be fine. I'm going to use feeler gauges and test the gap in the infinijector.

re: looking ot buy a flowmeter, what specs will I need?

Is there a cheap analog flowmeter? Like the stuff you see on mcmaster, except not ridiculously overpriced? Maybe I'll just weigh the fuel instead.....

re: Measuring operation frequency?

cool, as long as it measures frequency it's good by me lol. what about amplitude? would a pulsejet with with the same frequency but more amplitude produce more thrust than the pulsejet with the lower amplitude?
