Product Overview
The Ultrasonic Gas Flow Meter uses advanced ultrasonic gas sensing technology, designed specifically for applications such as biogas engineering stations, city natural gas distribution metering, and trade measurement. This device accurately measures gas flow and collects on-site pressure and temperature data in real time, supporting standard flow calculations. Its unique methane concentration measurement capability gives it an edge in biogas engineering, particularly in flow metering, acceptance, and supervision, helping to optimize measurement solutions. The design, with no mechanical moving parts, ensures consistent accuracy over time and is suitable for harsh environmental conditions.
Key Features
- High Accuracy and Stability: Employs ultrasonic gas sensing technology, providing precise measurements with temperature and pressure compensation functions for accurate standard and cumulative flow calculations.
- Strong Corrosion Resistance: Features a specially designed ceramic ultrasonic transducer, capable of operating under high H₂S and high moisture conditions, ensuring excellent corrosion resistance.
- Unique Methane Concentration Measurement: In addition to measuring gas flow, the device can measure methane concentration in biogas, ensuring compliance with biogas subsidy policies and preventing improper subsidy claims from using air.
- Low Flow Measurement Capability: Particularly suitable for small-scale biogas projects with "peak-valley" flow characteristics, ensuring accurate low-flow measurement.
- No Moving Mechanical Parts: The measurement components are free from wear, requiring no maintenance over time, ensuring stable accuracy.
Applications
- Biogas Engineering Stations: Used for flow metering, acceptance, and regulation, with a key focus on methane concentration measurement to ensure compliance and optimize policy execution.
- City Natural Gas Distribution Metering: Provides high-accuracy flow measurement for natural gas, supporting trade metering and system monitoring.
- Environmental and Energy Industry: Ideal for gas flow monitoring in biogas, natural gas, and other gases, especially in applications that require real-time methane concentration measurement.
- Small-Scale Biogas Projects: Well-suited for handling peak-valley flow characteristics, ensuring reliable and accurate flow measurement.
