Rotameter flow meters are devices that can measure the flowrate of liquids and gases. Generally, the rotameter is a tube made of plastic, glass or metal combined with a float, which responds linearly ...

Abstract: Currently used flow equation of rotameter was obtained by analogy of orifice meter, which is not rigorous in theoretic. In this paper, according to the fluid motion characteristics in ...

The word rotameter is assumed to be a generic name for a variable area flow meter, describing a freely rotating float visible in a glass tube. However Rotameter is a fairly carefully trade-marked word ...
