751 - Flowmeter Brochure

These flowmeters operate according to the variable area principle, where a float is suspended in upward flowing media in a tapered plastic tube. The vertical position of the float within the metering tube depends on the flowrate of the media. The measuring range is usually 1:10 where the scale is uniformly graded on the measuring tube. The measured value is determined by the upper edge of the float and can be easily read on the scale.
