Wedge meter

A wedge meter is an engineered primary flow element for extremely challenging applications. Due to its robust design and possibility for direct attachment of a diaphragm seal assembly, the primary element is also perfectly suited for differential pressure flow measurements of erosive, abrasive and solids-containing fluids without the risk of clogging.

Product highlights

  • Low maintenance due to robust design
  • Long service life, low wear
  • For highly viscous and particle-laden fluids
  • Low risk of clogging

Typical applications

  • Applications with high flow velocities
  • High viscous, solids-containing, corrosive and abrasive fluids
  • Bi-directional measurement
