How to calculate hydrogen flow rate
Thread Content
Our factory uses an orifice flow meter at the outlet of the hydrogen compressor, and the measurement is usually accurate. However, the density of hydrogen has increased recently, and the outlet flow meter indicates about 15% higher than usual. How do experts calculate the hydrogen flow meter? Is there any formula?
There should be a formula on the product description of the flow meter, because this is a very old measurement technology and is relatively reliable. Its formula includes compensation for different pressures and temperatures. If there is no problem yourself, it should be that the outlet pressure or temperature of your compressor has changed, which is why it is too high.
Good things are only happy when everyone shares them.
