Why CO2 fire extinguisher has no gauge?

Class B size ratings range from 1 to 640. This number estimates the square footage an extinguisher can cover.
How big is the discharge scope of a CO2 extinguisher?
The discharge scope of CO2 extinguishers is relatively small. Once the carbon dioxide is dispelled from the device, it will naturally spread, as all gases do.
