AWISEL
Balometers
For directly measuring and balancing supply and exhaust airflow.
Where it fits
Direct airflow at the terminal.
Balometers support direct supply and exhaust airflow measurement at diffusers, grilles and terminal units. They are useful when a direct capture method is clearer than point-by-point velocity calculation.
They are commonly considered for HVAC balancing, healthcare ventilation checks and cleanroom supply or exhaust reviews.
Terminal details
Start with the terminal.
Share diffuser, grille or terminal dimensions and whether the flow is supply or exhaust.
Expected airflow range and room use help determine the suitable instrument configuration.
Ceiling height, terminal position and hood fit affect practical use on site.
Product options
Review balometer options with their related documents.
Compare each product by its intended use and distinguishing capabilities, then consult the manufacturer documents for detailed specifications.
