RECT FLOW METER

The PFS RECT Flow Meter redefines flow measurement with its suspended, inverted-dyke throttle block and rectangular flat bottom. Inspired by Venturi and Wedge meters, this hybrid design fuses their strengths into a superior solution, excelling in gas, steam, and liquid flows—including slurries and abrasive media.

Innovative hybrid design: Venturi’s stability + Wedge’s resilience.
Accuracy: ±0.25% to ±0.5% (vs. ±1%-5% for orifice meters).
Rangeability: Up to 200:1 (vs. 10:1 for orifice).
Durability: 2-5x longer life than wedge meters.
Low head loss: 10%-25% DP (vs. 50%-80% for orifice).
Compact: 4D upstream run (vs. 15D+ for traditional meters).

KEY ADVANTAGES

Venturi Influence: Streamlined throttling channel minimizes turbulence and head loss, outperforming orifice meters.
Wedge Influence: Open, hardened throttle block with obtuse edges prevents clogging and resists erosion, unlike sharp-edged designs.
Combined Excellence: Merges wide rangeability, durability, and efficiency into a single, groundbreaking meter.
