BTW, Are you sure your King Flow meter indicator isn't inserted backwards?

Yours has a different floating cone of sorts, but I have three of them and the tapered portion always flares upwards narrow to wide with the direction of flow). I suppose you could verify accuracy by doing a 5 gallon bucket/stopwatch test as I did here, but that caught my attention. Now that I look at it, it might be ok and just a different float/indicator than my three.
Interesting - I haven't calibrated it. I have got it hooked up right but I never did anything to change the float. I bought it off ebay supposedly new, and it looked brand new, so I'm not sure what to make of it. I'll have to do your 5 gallon test and confirm!

I found this image which looks the same as yours:



Here's a close up of mine:



They are different shapes so it's not just the same float but upside down. Plus mine is the 3.5gpm range not the 5gpm like the others I've seen - still it's weird!.
