Product Overview
The Ultrasonic Gas Flow Meter uses advanced ultrasonic sensing technology to provide high-precision flow measurement for biogas and other industrial gases. In addition to flow measurement, the device supports gas composition analysis, including real-time monitoring of methane (CH₄) concentration. Equipped with a specially designed ceramic ultrasonic probe, it offers excellent corrosion and moisture resistance, making it ideal for harsh environments. Its reliable performance and unique design make it highly suitable for industrial production, environmental monitoring, and energy management applications.
Working Principle
The flow meter calculates gas velocity by measuring the time difference of ultrasonic signals traveling through the gas. Flow rate is then determined using gas density and temperature data. An integrated temperature sensor provides compensation to ensure accurate measurements under varying environmental conditions. The ceramic probe also enables real-time detection of key gas components, such as methane, for compositional analysis.
Key Features
- Accurate Flow Measurement & IC Card Billing: Precisely measures gas usage and supports IC card billing; automatically shuts off gas in case of unpaid accounts.
- High Corrosion Resistance: Ceramic ultrasonic probe withstands high H₂S concentrations and humid environments, ensuring long-term stability.
- No Mechanical Wear: Fully non-mechanical design avoids wear and tear, maintaining measurement accuracy over time.
- Temperature Compensation: Built-in temperature sensor ensures environmental changes do not affect flow readings.
- Methane Concentration Monitoring: Measures CH₄ levels in real time, meeting biogas subsidy monitoring requirements.
- High Pressure Tolerance: Designed to handle high-pressure conditions in various industrial settings.
Applications
- Biogas Flow Measurement: Suitable for biogas plants and projects with strict flow and gas composition requirements.
- Natural Gas and Industrial Gas Monitoring: Provides precise flow measurement for natural gas and other industrial gases.
- Energy Management & Environmental Monitoring: Supports accurate data collection for efficient energy use and environmental monitoring.
- Biogas Subsidy Monitoring: Methane measurement ensures compliance with policy requirements for fair and transparent subsidy evaluation.
