气体流速
为气体应用选择传感器时，通过传感器的压降和量程取决于操作
温度、压力和流体成分。因此，在为任何特定气体应用选择传感器时
建议使用www.emerson上的尺寸和选择工具确定每个传感器的尺寸。com/flowmeasurement将
报告所考虑的每个流速和流量计尺寸的实际流速和声速。
使用以下方程式确定标称和大气体质量流率的一般建议：

建议费率。当马赫数大于0.3时，大多数气流变得可压缩且显著
无论测量装置如何，压降都可能增加。

气体大流量不得大于大液体流量。假设两个费率中的较低者适用。

Therefore, when selecting a sensor for any particular gas application, it is highly recommended that each sensor be sized using the sizing and selection tool at www.emerson.com/flowmeasurement that will report both the actual velocity and the sonic velocity for each flow rate and meter size considered. Use the following equation to determine general recommendations on nominal and maximum gas mass flow rates: (ݏܽ݃)ṁ (ݏܽ݃)ρ * ܯ% =  *  ܸܱܵ  *  1 4 ܦ* π 2   *  2 (for sensors with dual‐tube design) ṁ(gas) Gas mass flow rate %M Use Mach number “0.2” for calculating typical nominal rate; use Mach number “0.3” for calculating maximum recommended rate. When Mach Numbers are above 0.3, most gas flows become compressible and significant increases in pressure drop may occur regardless of measurement device. ρ(gas) Gas density at operating conditions VOS Velocity of Sound of the measured gas D Internal diameter of the measuring tube For a complete list of sensor tube IDs, see the Micro Motion ELITE Coriolis Flow and Density Meters Technical Data Sheet. Note Gas maximum flow rate can never be greater than the maximum liquid rate. Assume that the lower of the two rates is applicable.
