Delta Bar Flow Meter Source: Kaifeng Willey Flow Instrument Co., Ltd. | Release Time: October 6, 2011, 10:14:38 | Views: 20 Delta Bar Flow Meter: The Delta Bar (Deltaflow) averaging pitot tube flow meter has no essential difference in cross-sectional shape and structure compared to the diamond shape. It is an insertion-type flow instrument that estimates flow by measuring the velocity at several points along the diameter of the measurement pipe. However, while general averaging pitot tube materials are often made from 316 stainless steel, Deltaflow frequently uses 1.4528 or Hastelloy steel, with temperature resistance as low as -200°C and as high as over 1000°C, making it suitable for various corrosive media.
Main Features:
- Can measure various gases.
- Low pressure loss, energy-saving.
- Shorter straight pipe section requirement than averaging pitot tubes.
- Higher accuracy, ±3%～±1% uncertainty.
- Can measure bidirectionally.
Main Technical Parameters:
- Nominal Pressure: 12MPa
- Nominal Bore Size: 50～6000mm
- Accuracy (Uncertainty): ±3%～±1%.
