The classic venturi is also known as the classical venturi, commonly known as the standard venturi. Comply with ISO5167 or GB/T2624 standard. It is used to measure the flow of single phase stable fluid in closed pipe, and is often used to measure the flow of air, natural gas, gas, water and other fluids
■ Simple structure, durable, stable performance.
■ Small pressure loss, saving the energy required for fluid transportation.
■ In diameters from 50 to 1200, no real flow calibration is required. Beyond this range, you can refer to design and manufacture. When higher accuracy is required, real flow calibration can be carried out.
■ Body installation size is long, for large caliber instrument, is not easy to transport installation.
Nominal diameter (mm) | DN50~ DN1200 (~2600) |
Nominal pressure (MPa) | 0.25~4.0(~6.3) |
Accuracy (uncertainty) | ±0.1% to ±1.5% |
It is used to measure the flow of single phase stable fluid in closed pipe. It is often used to measure the flow of air, natural gas, gas, water and other fluids.
