ABSTRACT:
A method of measuring dynamic air pressure on a ground surface beneath a negative air system which is comprised of a rotatable negative air pressure element with a deck unit having a top with side walls and an open bottom involves placing the system on an elevated horizontal platform located in spaced relation to the deck. The system is then made operative. Measurements are then made of the air pressure at a plurality of locations adjacent the platform to determine if the air pressure at such locations is such that predetermined values are met. The apparatus for performing the aforesaid method has a horizontal platform with a plurality of apertures therein. The platform is adapted to support the negative air system. A plurality of air pressure sensors are mounted in spaced locations on the platform and are located in the lower end of hollow extending tubular pressure taps. The sensors are operatively connected to a monitor to permit the dynamic air pressure to be read adjacent each aperture when the operating negative air system is placed on the platform over the apertures.
