High Accuracy & Repeatability
Adopts precision-engineered rotary lobes to achieve ±1.0% measurement accuracy with excellent repeatability, ensuring reliable gas flow data for industrial billing and process control.
Wide Turndown Ratio
Offers a wide turndown ratio (typically 20:1 or higher), enabling accurate measurement across low to high flow rates—ideal for gas flows with significant load variations.
Durable & Corrosion-Resistant
Constructed with high-strength stainless steel or cast iron body, resistant to corrosive gases such as biogas, LPG, and natural gas. Features wear-resistant rotor coating for extended service life.
Flexible Output Options
Supports pulse, 4-20mA, RS485 Modbus, and LCD display. Easily integrates with PLC, SCADA, or remote monitoring systems for industrial automation.
Low Pressure Drop
Optimized rotor design minimizes pressure loss across the meter, reducing energy consumption of downstream blowers or compressors—perfect for low-pressure gas networks.
