  • Particle measuring system with sonically measured flow rate
    Patent number: 5501113
    Abstract: In a particle measuring system, a burette is provided to enable the rate of flow to a particle sensor of the particle measuring system to be continuously monitored and controlled. The burette has a central chamber and an outer chamber from which the central chamber can overflow. The central chamber of the burette is connected with the flow sample and the rate of flow through the particle sensor is measured by measuring the rate of displacement of the surface of the liquid sample in the central chamber. The rate of sonic transmission through the sample is measured by reflecting pulses from the surface of the sample at the time the central chamber overflows.
