    Did you know...

    that the OPTISONIC 7300 Biogas is the only ultrasonic flowmeter for biogas covering diameters up to DN 300 / 12”? This is particularly beneficial for producers of large biogas volumes for cogeneration or further upgrading to grid quality. The enhanced transducer range of the meter enables operators to handle a wide variety of gas compositions –  even including very wet biogas with high CO₂ content.

    Discover how a Scandinavian biogas producer benefits from the extended range and  optimised design of our biogas flowmeter.
