2. Continuing from yesterdays question, we believe it is atmospheric pressure behind the metering valve. So, how to measure this outlet The word measurement can be understood as calibrating flow rate or daily measurement. There are multiple options based on the approximate range and accuracy requirements of gas flow rate: 1. Small flow rates below 1 L/min can be measured/calibrated using the most basic but accurate soap bubble flowmeter. It is particularly suitable for situations where the back pressure is zero. 2. There are different types of rotameters available for flow rates ranging from 0.01 to 100 L/min, and the accuracy is still acceptable. 3. Mass Flow Meter (MFM) is available for flow rates ranging from 0.01 to 1000 L/min, with high accuracy. 4. The flow rate ranges from 1-100 Nm3/h and can be measured using a critical Venturi nozzle (which is also one of the standard methods for measuring gas flow), with high accuracy. Standard English documents can be found online. 5. Larger industrial flow rates are measured using orifice pressure differential flow meters, vortex street flow meters, etc., with acceptable accuracy. Of course, the above traffic ranges are roughly divided. Based on the "steel cylinder" you mentioned earlier, I understand that you want to calibrate the flow curve of the measuring valve at different scales. I estimate that the flow rate should not exceed 200 L/min (at this flow rate, a 51 liter nitrogen cylinder can be emptied in 1 hour). A mass flow meter can be used to calibrate the measuring valve, and then the mass flow rate can be converted to standard volumetric flow rate based on the ideal gas equation according to the gas composition and approximate molecular weight. The advantage of using MFM calibration is that there is no need to worry about pressure changes only in the mouth. It measures the molecular flow rate and has an automatic compensation function for pressure. Usually, metering valves have their own calibration curves, so sometimes you only need to calibrate a few points (such as 10, 50, 100% range) for flow verification. I dont know if my understanding of your question is correct.
