Ultrasonic Gas Flow Meter for High-Corrosion, High-Humidity Biogas

Product Overview

The Ultrasonic Gas Flow Meter is designed for high-corrosion, high-humidity environments, such as biogas applications. It uses an innovative bypass ultrasonic measurement technology to address common issues in traditional ultrasonic flow meters, including sensor corrosion, condensation, and CO₂ interference. By guiding a portion of the gas through a bypass pipeline for measurement, this design improves signal quality, reduces interference, and ensures high-precision flow measurement in large-diameter pipes and harsh conditions.

Working Principle

The meter employs a bypass ultrasonic measurement method, directing gas through a bypass line where an ultrasonic sensor measures flow velocity. The system automatically compensates for signal attenuation caused by CO₂ concentration, moisture, and temperature variations. The bypass design ensures uniform flow, directs condensate away from the sensor, and minimizes interference. Its corrosion-resistant construction reduces direct contact with corrosive gases, extending sensor lifespan and allowing maintenance without production interruption.

Key Features

• Enhanced Signal Quality: Bypass pipeline reduces CO₂ interference and improves measurement accuracy, ideal for large-diameter applications.
• Minimized Flow Disturbance: Optimized bypass design ensures uniform flow distribution and reduces measurement error caused by turbulence.
• Condensate Management: Guides condensation out of the measurement path, protecting the ultrasonic sensor.
• Superior Corrosion Resistance: Limits direct exposure to H₂S and other corrosive gases, extending sensor and pipeline life.
• Simplified Maintenance & Lower Costs: Measurement components are separated from the main pipeline, enabling repairs without stopping production.
• High Stability: Maintains reliable operation in high-humidity, high-corrosion biogas environments, ensuring long-term data accuracy.

Applications

• Biogas Projects: Accurate flow measurement in biogas plants and digesters under high humidity and corrosive conditions.
• Natural Gas Networks: Suitable for flow monitoring in pipelines, especially in challenging environmental conditions.
• Environmental Monitoring & Energy Management: Provides precise data for gas resource metering and energy efficiency monitoring.
• Agricultural & Industrial Fermentation: Measures flow in processes with corrosive and moisture-laden gases.
