METHOD AND SYSTEM FOR MEASURING A FLOW |
摘要 |
A method is described for measuring a flow of gas passing a flow meter device. The device causes a pressure drop when a gas flows through it. The pressure drop across the device is a measure of the gas flow. The device is configured as a gas permeable tube that has a flow channel on the upstream side along the tube configured so as to decrease the cross-section of the channel downstream of the gas permeable tube. This provides for a minimum volume in the channel upstream of the device's pressure-drop-generating component. |
