@btrueblood:
Yes, you are right. I prefer a first-principle method, to avoid expensive external calibration costs every year.
From 1 to 6 m3/h the cheapest (and only?)way is to buy a gas meter with calibration. It is same price as for a calibration of the old gas meter. But in the range 6-12 m3...
For Dp orifice 100 Pa Re(pipe diameter) = 1539
For Dp orifice 200 Pa Re(pipe diameter) = 2165
For Dp orifice 300 Pa Re(pipe diameter) = 2645
OK, it is very low(thats why I ask)
What other measurement methods can I then use, else than mass flow meter or volumetric gas meter. We are talking...
Hello
I measure flow with an orifice, and I am calculating the flow according to ISO 5167-2. However at some flows, the Reynolds number for the pipe is not large enough according to ISO 5167-2, but I would like to know if it is possible to calculate the flow despite of that, or perhaps...
