Wedge Meters

Durable, Accurate, and Built for Challenging Conditions

Daniel® Wedge Meters provide reliable and precise flow measurement in some of the most demanding industrial applications. Designed to handle abrasive, corrosive, and solid-laden fluids, these meters excel where other differential pressure (DP) elements fall short. Whether you’re measuring viscous fluids, slurries, or gases, the robust design of the wedge meter ensures long-term durability and performance in even the harshest environments.
