gear flowmeter is a classic positive displacement flowmeter. Its operating principle involves a pair of precision-machined elliptical or circular gears (hereafter referred to as gear wheels) meshing and rotating within a metering chamber.

Deskripsi
Product Advantages:
The core value of the bevel gear flowmeter lies in its unmatched high precision, adaptability to high-viscosity media, and extensive reliability.
- Exceptional Measurement Accuracy: Employing volumetric measurement principles, it achieves accuracy as high as ±0.5% R or even ±0.2% R, ranking among the most precise flowmeters. This enables direct use for trade settlement, minimizing disputes and losses.
- The King of High-Viscosity Measurement: Measurement accuracy remains unaffected by changes in fluid viscosity (even at high viscosities). Higher viscosity reduces internal leakage, enhancing measurement precision and perfectly solving the challenge of metering high-viscosity fluids.
- No Straight Pipe Requirements: Accuracy remains unaffected by velocity distribution, eliminating near-total dependency on upstream/downstream straight pipe sections. This enables flexible installation, saves space, and is particularly suited for equipment with limited installation areas.
- Wide Turndown Ratio: Typical turndown ratios reach 10:1 or 20:1, maintaining high precision across an extensive flow range. This satisfies measurement needs from minimal flow rates to full-load flow conditions.
- High-Pressure Compatibility: Its robust mechanical design withstands extremely high pipeline pressures (up to tens of MPa), making it suitable for high-pressure injection, reactor feed, and similar applications.
- Multiple Signal Outputs: Supports pulse signals (for high-precision measurement and quantitative control) and 4-20mA analog signals (for remote transmission and DCS/PLC system integration), along with protocols like HART.
Core Application Areas:
- Petrochemical Industry: Trade transfer and process control for high-viscosity media such as crude oil, fuel oil, lubricants, asphalt, and resins.
