Variable Area Flow Meters
Custom Engineered Flow Meters
When your process cannot be served by a standard variable area (VA) flow meter configuration, the Brooks Applications Engineering team helps define a fit-for-purpose solution—covering feasibility, form, fit and function from first review through project offering.

From closest standard configuration to custom flow solution
Start with a standard Brooks rotameter, then collaborate with experienced applications engineers to determine what can be customized for your challenging process conditions, corrosion-resistance requirements or spatial constraints.
Application Support
Experienced applications engineers help identify the right solution and translate process requirements into a clear product direction.
Engineering Feasibility
Engineering support helps determine feasibility, form, fit and function before a custom solution is proposed.
Complete Project Coverage
Brooks reviews application aspects and project needs to reduce gaps in the offering and align the configuration with the real operating environment.
