# Dual-Beta Orifice Plates

> Two independent β sections in one assembly, each designed to ISO 5167-2:2022 — enabling wide-range measurement with standardized orifice elements.

## Specifications

- **Beta ratio**: β₁ 0.50–0.65 (high flow) / β₂ 0.20–0.35 (low flow)
- **Accuracy**: ±0.5%–0.8% per section (application dependent)
- **Turndown ratio**: 50:1 (guaranteed accuracy); 100:1 (theoretical)
- **Pipe size range**: DN100–DN400
- **Standard**: N/A
