Main performance features
Every contour, angle, and surface engineered to enforce stable differential-pressure behavior.

Velocity-Profile Simulation
We model flow contraction and expansion to achieve a stable velocity distribution at the throat, enhancing overall measurement uniformity.
Optimized Flow Passage Geometry
Internal contouring and mirror polishing reduce turbulence and pressure loss, maintaining smooth flow contraction and recovery in real applications.
Pressure-Extraction Stability
Positive and negative pressure pathways are designed to minimize turbulence influence and provide a clean differential signal under varying flow conditions.
Load-Condition Verification
Testing across various flow rates ensures predictable signal response and preserves meter reliability under industrial fluctuations.
Built for Dimensional Accuracy and Stable Flow Behavio
Precision forming and comprehensive verification ensure Venturi reliability over time.
