1. Please advise on the selection of a natural gas flow meter..

Firstly, when selecting a flow meter, it is necessary to replace the standard cubic meter with a volumetric cubic meter, that is, convert the standard cubic meter flow rate to a volumetric flow rate. Assuming that the flow rate is 500m3/h and the standard cubic meter is 500Nm3/h, that is, 500Nm3/h is measured before pressure regulation. The pressure before pressure regulation is calculated at 0.4MPa, which is a gauge pressure of 4bar, an absolute pressure of 5bar, and a volumetric flow rate of 500/5=100m3/h. The flow rates marked on the flow meter selection table are all volumetric flow rates. Therefore, you can check the table according to 100 cubic meters, and the specifications larger than 100 cubic meters can be used. The answer is that according to this working condition, you need to choose a Roots meter with G100 specification, usually DN80, and a volumetric flow rate of 160. Fang, meet your requirements at 0.4MPa The flow rate is 500 standard cubic meters (with a volume flow rate of 100 cubic meters), but you also need to pay attention to whether the pressure before pressure regulation is the minimum operating pressure, because the lower the pressure, the larger the flow meter requir
