The air volume measurement test device is an air volume testing system developed and manufactured based on the GB/T1236 standard and advanced Japanese technology. The basic testing principle is to simulate the actual working state of the test 

specimen in the testing wind tunnel (using an auxiliary fan to make the outlet pressure of the test specimen consistent with the requirements),

Then measure the pressure difference on both sides of the nozzle in the wind tunnel, calculate the corresponding wind speed using a standard formula, and finally multiply it by the nozzle area and relevant flow coefficient to obtain the air volume.

The air volume measurement test device is an air volume testing system developed and manufactured based on the GB/T1236 standard and advanced Japanese technology.

The basic testing principle is to simulate the actual working state of the test sample in the testing wind tunnel (using an auxiliary fan to make the outlet pressure of the test sample consistent with the requirements), then measure the pressure 

difference on both sides of the nozzle in the wind tunnel, calculate the corresponding wind speed using a standard formula, and finally multiply it
