Flow meter

The plug-in venturi is a classic venturi with a small diameter inserted into the center of the large pipe, and the differential pressure of the inserted venturi is measured to obtain the flow rate, which can be used for gas flow measurement of large diameters (such as blast furnace gas, smoke Dao Qi, etc.).

Main features of plug-in venturi

◆Simple and firm structure.

◆Low pressure loss and energy saving.

◆Small size. Small installation size and low cost.

◆It has stable performance and can be used for process monitoring.

Main technical parameters of plug-in venturi:

◆Pressure-taking method: the upstream end uses the radial distance to take the pressure, and the downstream part uses the throat to take the pressure.

◆Nominal pressure: ≤6.3MPa

◆Nominal pass through: 50-2200mm

◆Accuracy (uncertainty): ±2.5%~5%

◆Scope of application: Reynolds number range ReD: 2x108≥ReD≥2x105
