What are the consequences if the flow rate through the manual metering valve exceeds the maximum flow rate of the valve? The word measurement can be understood as calibrating flow rate or daily measurement. There are multiple options based on the approximate range of gas flow rate and accuracy requirements: 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 a standard volumetric flow rate based on the gas composition and approximate molecular weight, according to the ideal gas equation. The advantage of using MFM calibration is that there is no need to worry about only changes in port pressure. 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.

3. What is a mass flow meter

1. What is a mass flow meter: Mass Flow Meter (MFM), a precision sensor used to quickly and accurately measure the flow rate of process gases. The mass flowmeter mentioned here is mainly used for low pressure, low flow single or mixed gases, with low pressure generally below 1Mpa and a maximum of 3Mpa; The flow range is generally 0.1 sccm to 5000 slpm; Single gases such as common air, helium, argon, etc. require relative dryness and purity; For mixed gases, it is necessary to specify the type and proportion of gases. 2. What parameters can be obtained from a mass flow meter? The Yidu mass flow meter can accurately obtain five major parameters of gas: real-time temperature, pressure, operating flow rate, standard flow rate, and cumulative flow rate. The units of a mass flow meter are generally SLPM (liters per minute under standard conditions) and SCCM (milliliters per minute under standard conditions), both of which are volumetric flow units under standard conditions. The measurement scale is defined as 101.325KPa and 25 ℃. The composition of a mass flow
