WedgeX Flow Meter

WX Wedge-X Flow Meter

+/- 4.00% Uncalibrated Uncertainty
Integral Manifold, Replaceable Wedge

  • Line size: 2 inches
  • Head loss % of Differential: 25 to 60 percent
  • Recommended pipe Reynolds number: Must be greater than 5000 for basic accuracy


The Wedge-X flow meter design is derived from the standard wedge flow meter, but allows for a direct coupled differential pressure transmitter, and a replaceable wedge which results in a compact and cost-effective unit that virtually eliminates both gauge line induced and plugged tap related measurement errors.

The replaceable wedge feature is an extremely fast and cost-effective way of addressing situations like erosion of the wedge. A wedge can also be replaced with a different size to increase or decrease dP as needed.

The wedge flow meter is intended for high-density, slurry type, or contaminated line fluid applications, including difficult-to-meter, air entrained liquids. WedgeX meters can be customized to measure fluids over a large range of pressures and Reynolds numbers; making them ideal for many applications, including shale gas extraction.
