Product Description

Ultrasonic Flow meter




Ultrasonic Gas Flowmeter BF-3000B is based on bypass measurement method, which can measure the flow rate of biogas,  natural gas, air and other gases. In the bypass type flow meter, flow in the main line is inferred by measuring the flow in a small bypass line, it can effectively solve the problems such as moisture and improve the measurement accuracy.




• No movable parts, no pressure drop.
• Ultrasonic technology, high precision, long lifetime.
• Combination of the pressure, the flow measurement of large pipeline available.
• No effect if installation and maintenance when the pipeline is working.
• Low power consumption. 5 years Lifespan.
• All-in-one detecting design, measure flow velocity, pressure, 
temperature and methane concentration directly.
