# Bore-Venturi Balanced Flow Meters

> Eight bore-venturi holes with an integrated central cone — combining balanced flow conditioning with venturi pressure recovery for high accuracy and low pressure loss.

## Specifications

- **Beta ratio**: 0.30–0.70 (design range)
- **Accuracy**: ±0.5% of rate (with individual flow calibration)
- **Turndown ratio**: 20:1 (CFD validated at ±1% stability for β=0.55–0.60)
- **Pipe size range**: DN50–DN600
- **Standard**: N/A

## Applications

- Natural gas custody transfer
- Steam distribution networks
- Refinery process lines
- Compressed air and industrial gases

## Features

- 8 bore-venturi holes + central cone architecture
- Cd 0.80–0.92 — 30–50% higher than standard orifice plates
- CFD validated across 63+ operating points (publicly documented)
- Integrated flow conditioning reduces straight-run requirements
- Pressure loss 40–60% lower than standard orifice plates

## Design Validation

- CFD-predicted coefficient stability ±1.0% (pre-calibration design reference only)
