Description
Classic Venturi, also known as Classical Venturi, is often referred to as Standard Venturi. Its design, manufacture and use are in line with international standards ISO5167 or GB/T2624. Commonly used in the measurement of liquid and gas flow.
◎Main Features
Simple structure, durable and stable performance.
Pressure loss is small.
The structure size is large and the installation size is long.
Real flow calibration is not required, and real flow calibration can be performed when higher accuracy is required.
◎Main technical parameters
◆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 diameter: 50~2200mm
◆Accuracy (uncertainty): ±1.0%
◆Scope of application: opening diameter ratio β:0.4≤β≤0.7
Reynolds number range 2×10"≥ReD≥2x10"Outflow coefficient C:C=0.985
