Selection Notes
1. Pipe diameter: pipe diameter, wall thickness and material
2、Measuring medium
3、Medium temperature (℃)
4、Medium working pressure(MPa）：Maximum pressure, normal pressure, minimum pressure
5、Medium working flow (m3/h、kg/h、Nm3/h) ：Maximum flow, normal flow, minimum flow
6、Medium viscosity (mPa.s)
7、Medium density (kg/m3)
