How can we confirm that the amount of exhaust gas being treated is 500 cubic meters per hour?

The amount of waste gas that passes through the spray tower and is then absorbed by activated carbon is designed to be 500 cubic meters per hour. However, the fan selected for this system has a capacity of 1000 cubic meters per hour. So how can it be ensured that the amount of waste gas processed remains at 500 cubic meters per hour? Could more be drawn in, increasing the amount of exhaust gas that needs to be treated? Is it necessary to install an exhaust gas flow meter for the pipeline when the owner arrives?
In general engineering design, some margin is always reserved; designing for 500 and handling around 600 is usually sufficient as well. If it is necessary to confirm whether it is 500, then install flow meters before and after the adsorption unit; the inlet flow minus the outlet flow can be considered as the amount of adsorption.
Use a pitot tube to measure the flow velocity; give it a try
Slight negative pressure means that too much gas has been removed
