My Surprising Flow Rate Results

[Snyxxx]

At least to me they were.

It all started when I finally got around to add my bigNG/Sensorbus to my system listed in my signature. When I attached the DDC's RPM cable to the flow meter port of the Sensorbus, it showed much different flow rates depending upon the sample rate which made no sense.

This is better described in this thread:

I took Virtualrain's advice and performed a flow test on my own to see the real answer.

Here is my crude testing facility.

I watched the time on my watch for 2, 4, 6 and 8 liters to pass. I did this for five attempts and the results were very close each time.

Result was 6.5 liters/min. I adjusted the impulse rate within the bigNG software to show this flow rate.

Out of curiosity, I ran the same test with the pump only.

Results showed 12 liters/minute. This is about on par from what I see on the web. Just the Storm and EK 8800 FC Block eat up almost half the flow rate. Also, I am using 3/8 tubing as well and do not consider the PA120.2 a big pressure drop. However, I am pleased that there is still this much flow after with these two blocks. My D5 certainly did not perform this well.

More results continued on next post since I do not know how to post more than five pictures in a single post.
