ABSTRACT:
A process for monitoring fluid density by use of a fluidic jet oscillator (26) absent the necessity for a high-precision pressure regulator. Fluid is delivered to the fluidic oscillator (26) via a pressure divider (28). As the fluid flows through the oscillator the latter generates a pressure wavetrain at a frequency which is indicative of the density of the fluid, but is inaccurate to the extent that the pressure difference across the oscillator varies from a predetermined value. A differential pressure transducer (30) senses the pressure difference. Accordingly, the process is adapted for use with a gated sampling and control system (84) which operatively responds to the oscillator output only when the differential pressure is substantially in accord with a predetermined value thereof.
