GF721 Explosion-proof Clamp-on Gas Ultrasonic Flowmeter

The GF721 Series Gas Ultrasonic Flowmeter adopts ultrasonic transducers, which can effectively mitigate the impact of dust, liquid droplets, and other impurities in the fluid on signals, with a maximum tolerance for dust or liquid droplet content of 10% (v/v). It supports multiple installation methods, including the use of clamp-on sensors. Among these, the clamp-on sensor is equipped with a solid-state coupling pad, featuring maintenance-free operation that allows long-term service without the need for coupling agent replacement. The flowmeter covers a maximum pipe diameter of DN600 and is equipped with a unique temperature buffer plate system, enabling temperature measurement ranging from -200℃ to 400℃.
