Rotameters: The Reliable Mechanical Solution for Flow Measurement
Discover how this time-tested technology delivers accurate flow measurement without external power requirements
How Rotameters Work: Simple Physics, Reliable Results
Rotameters operate on Archimedes’ principle of buoyancy, combining fluid dynamics with mechanical simplicity:
- Tapered tube design (3-5° cone angle) creates variable flow area
- Float position indicates flow rate at equilibrium
- No external power required for basic operation
- ±2-5% accuracy across measurement range
