  • Hybrid passive/automated flow proportional fluid sampler
    Patent number: 6742404
    Abstract: The invention discloses a flow proportional fluid sampler. A turbine pump unit has a pump that is powered by the fluid flow of the test site, such as a stream, thereby eliminating the need for outside power for the pump and proportioning the volume of sample taken to the flow velocity. The invention also incorporates a simple pulse counter that monitor's the revolutions of the turbine propeller and can be used to measure velocity. The invention also provides a collection and distribution unit that can collect and store numerous samples in a small, light-weight container.
