The OPTISONIC 7300 is an ultrasonic transit-time flowmeter for process gases, combining the OPTISONIC 7000 flow sensor with a GFC 300 signal converter that has a built-in flow computer for standard or normal flow conditions. It measures with the same accuracy over a 100:1 range independent of gas composition, works from ambient pressure, and its full-bore body has no moving parts, no pressure loss and no drift. Typical services include natural gas production and distribution, chemical process, inert and fuel/waste gases, and petrochemical and refinery gas processing units.
