Abstract
An air flow manifold system for a production line calibration station. The air flow manifold system has a connector manifold connected to the production line calibration station, a vacuum source, a first manifold and a second manifold. The first and second manifolds connect the connector manifold to a vacuum source. The first and second manifolds each have a shut-off valve and a sonic nozzle controlling the mass air flow therethrough. The mass air flow through the first and second sonic nozzles are selected to have an optimal value for the calibrations to be conducted by the calibration station. An electrical controller sequentially activates the first and second valves sequentially supplying the specified mass air flow rates through the calibration station. Pressure and temperature sensors disposed upstream of the sonic nozzles permit an accurate determination of the mass air flow rates through the sonic nozzles.
