PURPOSE: The transportable digital apparatus for measuring an air amount of the multi-nozzle mode can minimize the air volume measurement error. CONSTITUTION: The blower discharges the air to the outlet. Fan is run. The sensor unit(170) comprises the suction static pressure sensor, the differential pressure sensor, and the discharging static pressure sensor and barometric pressure sensor. The suction static pressure sensor is connected to the air hose included in the duct. |
