Ultrasonic Flow Meter BF-3000BBF-3000B

BF-3000B Ultrasonic Gas Flowmeter is based on bypass measurement method, which can measure the flow rate of biogas, air, natural gas 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 sensor corrosion, and improve the measurement accuracy.
