Wedge-X Flow Meter (WX)

Compact & Cost-Effective Wedge-X Flow Meters

The Wedge-X Flow Meter from Primary Flow Signal builds on the proven performance of standard wedge meters, with a streamlined design that allows for a directly coupled differential pressure transmitter and a replaceable wedge element. This compact, all-in-one configuration reduces installation complexity, eliminates gauge line–induced and plugged tap errors, and provides a cost-effective solution for accurate flow measurement in challenging applications.

Wedge-X meters are engineered for high-density, slurry-type, or contaminated line fluids, including air-entrained liquids that are difficult to measure with other devices. With the ability to customize for a wide range of pressures and Reynolds numbers, the Wedge-X is well-suited for industries such as oil and gas (including shale gas extraction), mining, chemical processing, and other heavy-duty applications. The replaceable wedge feature further extends product life by allowing for quick and inexpensive replacement due to erosion, or by swapping in a different size wedge to adjust differential pressure as needed. Additional benefits of the Wedge-X meter include:

• Compact, Integrated Design: Combines the wedge element, meter body, and differential pressure transmitter into a single assembly—simplifying installation and reducing potential leak points.
• Replaceable Wedge Element: Provides a fast and economical way to address wedge wear or to change wedge sizing for different flow conditions without replacing the entire meter.
• Reliable in Harsh Applications: Performs consistently with slurries, viscous fluids, suspended solids, and contaminated or air-entrained liquids where other meters may fail.
• Extended Service Life & Durability: No moving parts and reduced susceptibility to erosion ensure long-term, low-maintenance performance.
• Versatile Operation: Bi-directional measurement, wide turndown ratio, and repeatability of ±0.2% make the Wedge-X adaptable to a wide range of process conditions.
• Flexible Installation: Mounts in any position, with robust construction that supports demanding industrial environments.

Typical applications include chemical and petrochemical processing of corrosive or abrasive liquids, pulp and paper operations involving fibrous slurries and stock flows, mining and mineral processing with abrasive slurries, and oil, gas, and refinery applications including crude oil, multiphase streams, and contaminated process fluids. Wedge-X meters are also well-suited for high-viscosity, solids-bearing, or entrained-gas liquids, including specialized applications such as shale gas extraction, where stable, repeatable measurement is critical under demanding conditions.
