Abstract:

This paper describes the development and operation of a unique laboratory calibration instrument employing fluidic oscillators as flow-measuring devices. The fluidic oscillator is composed of a laminar proportional amplifier in a negative feedback configuration. This arrangement allows great flexibility in design because of the availability of off the shelf C-format laminates. It has been shown that staging such devices can increase linear ranges of operation or turndown. The design goals of this instrument were to provide a highly accurate, noncontaminating, gas calibration standard to be used to calibrate gas chromatographs in the laboratory. Such a device was previously not available to the chemist and has thus advanced the state of the art for permeation devices.
