Variable Area Flowmeter - Rotameter

ROTAMETERs™ (Variable Area Meters) are named after ROTA, one of the European inventors of this flow principle in the beginning of the century. ROTA invented the rotating float, which is self-guiding and has less friction in the pipe so that a more precise measurement is possible.
Yokogawa ROTAMETERs are available with metering tubes manufactured from either glass, plastic or metal.
Our ROTAMETER™ family includes units 6mm to 125mm line sizes, temperatures from -180 to +400ºC, flange ratings to 1500#, ±1.6% accuracy class and turndown's of 10:1. ROTAMETERs™ offer a very low cost, easy to install solution to flow measurement.
Once considered as only a water or air flowmeter, ROTAMETER™ is now world proven in applications such as industrial gases, viscous/non conductive chemicals, steam and fuels.

I know you're trying to sell this to me, but I used your video to help me with understanding my chemical processing lab lol. Thanks!

I am glad it was helpful!

Hi, I'm Miko, I want to ask, I have an IP 66/67 rotameter, is there a calculation if calibrated with water as a medium, while the tool is for NaOH with a density of 1500 kg/m3, how do I calculate it if calibrated with water?

Good day sir, is it applicable to liquid refrigerant?

So it has nothing to do with rotation like the name suggests. I wish they would rename it to something else having to do with flow and/or variable area.

[@YokogawaTestMeasurement]

The first variable area meter created by Karl Kueppers was with a rotating float. A company in Germany named Deutsche Rotawerke GmbH improved the invention. Rota Yokogawa GmbH registered the name Rotameter after the name of the company. In the metal versions, as the float moves up and down, you can see the float os actually rotating. This is in the design of the product.
