These flowmeters operate according to the variable area principle, where a float is suspended in upward flow-ing media in a tapered plastic tube.The vertical position of the float within the metering tube depends on the flowrate of the media. The metering tube is graduated in suitable flow units (normally with 10:1 flow range) and the reading is taken in correspondence with the top edge of the float.Versions for liquids and gases are available, providing accurate and cost effective measurement with scales in l/h and Nm3/h. Other engineering units like LPM, m3/h or % together with double scales and special scales suited to the medium are available on request.
