  • Flow monitoring system
    Patent number: 4035646
    Abstract: A flow monitoring system which utilizes the decay of a measurable parameter of the flowing fluid by measuring the magnitude of the parameter at two spaced points along the flow of the fluid. Accurate measurements are enabled by the elimination of detector identity and calibration problems by repeatedly translating one detector between first and second positions external to the fluid conduit along the flow path of said fluid. This translation is preferably accomplished by a pendulum device with the detector positioned at the end of the pendulum.
