Product Overview
The Vertical Ultrasonic Biogas Flow Meter is a high-precision vertical-design flow meter specifically developed for biogas applications. It measures instantaneous biogas flow in real time and automatically calculates total flow along with related parameters. The meter offers low power consumption, cost-effectiveness, long service life, and easy maintenance, making it ideal for biogas projects, environmental monitoring, and other applications requiring accurate gas flow measurement. Its high repeatability and reliability provide stable data for efficient gas flow management.
Working Principle
The meter uses the ultrasonic transit-time method to measure gas velocity. The vertical installation allows gas to flow directly along the sensor path, enhancing signal stability and measurement accuracy. The sensor outputs instantaneous flow data, while the system automatically calculates total flow. Temperature and pressure compensation ensures accurate readings across varying operating conditions.
Key Features
