Averaging Pitot Tube

Features


  • Unique profile shape enables high flow rate turn down
  • Dual averaging for better accuracy
  • Suitable for Liquid, gas and steam flow measurement
  • Repeatability of measurement ± 0.1 %
  • Short upstream and downstream straight pipe lengths
  • Long term accuracy unaffected by wear.  Averaging pitot tubes are generally used for large line sizes or ducts where other primary devices become relatively expensive. Averaging Pitot tube comprises of following components:
  • Outer impact tube
  • Internal averaging tube
  • Low pressure chamber
  • Head
