  • Measurement device for measuring airflow volume and a ventilation resistance and having a specific opening for allowing an opening plate to be replaceable and differential pressure measurement arrangement
    Patent number: 10161771
    Abstract: A measurement device includes: a casing that includes a first air duct with an air inlet; a straightening grid; a first chamber; an opening plate including an opening; a second chamber; pressure sensors configured to measure a first pressure, a second pressure, and a third pressure, the first pressure being air pressure from the air inlet to the straightening grid, the second pressure being air pressure in the first chamber, the third pressure being air pressure in the second chamber; a specific opening configured to allow the opening plate to be replaceable; an open/close portion configured to open and close the specific opening; and a duct forming a second air duct between the measurement device and a measurement target.

  • Measurement device having variable opening orifice for measuring airflow volume and ventilation resistance of wind blowing apparatus
    Patent number: 10036660
    Abstract: A measurement device for measuring an airflow volume of a wind-blowing apparatus includes, a housing that includes an air duct with an air inlet and an air outlet, the air inlet being configured to take in air, the air outlet being configured to send out the taken air, an opening member installed inside the air duct, the opening member including an opening allowing the air taken from the air inlet to pass therethrough, pressure sensors configured to measure air pressures before and after the air passes through the opening member in the air duct, and an orifice provided on the opening member to change a size of the opening.
