The variable area flow meter is also known as a VA meter or as a Rotameter after Rota, one of the inventors of this flow principle at the beginning of the 1900s. Rotameters are based on one of the oldest and most well-known flow measuring technologies available.
Rotameter Advantages
• Relative low cost and ease of installation
• Robust and easy to maintain
• Applicable to liquids and gases
• No need for auxiliary power
• Eliminates Ex protection and electromagnetic compatibility issues
Rotameter Limitations
• Generally, variable area flow meters must be mounted vertically
• No output for data transmission
• Sensitive to changes in viscosity
• Sensitive to changes in temperature and pressure
Variable area meters or rotameters are well suited for a wide variety of liquid and gas applications, including monitoring chemical lines, flow in material-blending applications, filtration loading and makeup water for food & beverage plants.
