The FH1225 gas flow meter combines advantages of two complimentary ultrasonic flow metering methods: transit-time and transit phase. This results in unprecedented turn-down ratio, starting from the minimum velocity of 0.02m/s to the maximum gas velocity of 175m/s. The meter is insensitive to entrained liquids and clogging of transducers with heavy hydrocarbons and paraffins. Applications include flare gas measurement in small and medium pipes and associated gas flow measurement at wellheads.
