FPD470C – ABB Wedge meter flow element

FPD470CFPD470C wedge meters have DP connections for Chemical Tee remote seals. The flow element consists of a body and wedge flow restriction. This restriction creates a differential pressure in proportion to the square of the volumetric flow rate.

The FPD470C wedge restriction has no critical surface dimensions, or sharp edges, that will affect measurement accuracy as the result of normally expected wear.

  • Measures liquids, gas and steam
  • High Accuracy ±0.5 % of rate
  • Bi-directional flow
  • Low Reynolds number measurement (as low as Rd 500)
  • Minimum upstream and downstream piping requirements
  • Standard sizes 0.5 to 24 inch
