A rotameter, when used to indicate the rate of fluid flow in distilling plants, is essentially an area meter consisting of a __________.

🔍 Key Concepts

• Rotameter basic principle – how a float rises in a vertical tapered tube as flow increases • Variable area flow meter – what part of the device actually changes to indicate flow rate • Difference between float-type meters and piston/venturi/orifice-type flow meters

💭 Think About

• Which option describes a device where the flow rate is indicated by the vertical position of a floating element in a gradually widening passage? • Look for the choice that clearly shows a variable area (the flow path gets larger as flow increases) rather than a fixed opening with changing pressure. • Ask yourself: In a rotameter sight glass, what visible part actually moves as the flow changes?

✅ Before You Answer

• Verify which choice mentions a tapered (graduated) tube and a freely moving float in a vertical position. • Eliminate any option that relies mainly on pressure difference (like a venturi or orifice plate) instead of float height. • Check that the described device could be read directly by eye by seeing the position of a float against a scale.
