Reliability & Repeatability. Variable Area Flow Meters

Rugged. Economical. Easy to use flow measurement technology

When measuring liquid or gas flow at higher pressures and

temperatures not suitable for plastic, you can achieve accurate

flow rates with robust glass tube variable area flow meters

(rotameters) from Brooks Instrument. With a broader range of

flow rates available, glass tube rotameters are suitable for a variety

of liquids and gases.

Plus, the ability to easily see the float and direct flow scales on the

tube accommodate a variety of applications, whether in the lab or

in industrial processes.
