ABB uses robust design techniques for its unique swirl flowmeters FS4000 to provide high performance and reliable measurement of liquid, gas and steam. The swirl flowmeters use a specific frequency measurement principle which provides high accuracy of 0.5% and low flow measurement capability. Additionally, ABB’s swirl flowmeters help you save up to 80% installation space, because only shortest upstream and downstream sections are required. By offering large measuring spans, even small flow amounts during low consumption periods can be measured. Both high accuracy and low flow measurement capability help you save energy and natural resources and drive your processes to higher efficiency levels.
