Since the Venturi is part of the throttling device family, it possesses the characteristics of throttling devices. However, due to structural changes, it has some features that circular Venturi tubes do not possess. Compared to other rectangular duct air measurement devices, the rectangular Venturi air measurement device has smaller pressure loss, resulting in more significant energy-saving effects, typically with pressure loss only 10%-20% of the differential pressure value. In addition to low pressure loss, it has many other advantages.
Features
- Discharge coefficient of the throttling element is approximately 1.
- Very short required upstream straight pipe length (about 5D).
- Can be used for dirty flow measurement.
- Widely applicable in mixed-phase flow measurement.
