VD 520 – In-line differential pressure flow sensor

  • Ready-to-use compact design to minimise installation effort – therefore no volume converter (PTZ) is required
  • Provides volume flow, total consumption, temperature and pressure
  • Differential pressure sensor element with unique sensitivity, measuring with high accuracy even at flow rates below 2 m/s
  • Wide flow measurement range with extended measuring span through the use of measuring sections with a reduced inner diameter
  • Shorter inlet sections through the use of an averaging Pitot tube
  • Robust design, no moving parts
  • The sensor head can be removed for calibration
