The insertion venturi pipe is a classic venturi pipe with a smaller diameter inserted in the center of the circular pipe. The difference between the static pressure of the front straight pipe and the static pressure of the throat of the insertion pipe is measured, and then the flow is known, which can be used in the gas flow of the larger pipe diameter (such as blast furnace gas, flue gas, etc.).
■ Short installation size, easy installation, low cost.
■ Small pressure loss and energy saving.
■ Good stability, can be used for process monitoring.
Nominal diameter (mm) | DN500~ DN2600 |
Nominal pressure (MPa) | ≤2.5 |
Accuracy (uncertainty) | +3% to +5% |
Can be used in large pipe diameter gas flow (such as blast furnace gas, flue gas, etc.).
