  • Parshall Flumes

    Parshall Flumes are used in sewage treatment plants as well as industrial and municipal sewers. When it comes to fixed flow monitoring installations, the Parshall Flume is one of the most widely-used flume types. The special shaped open channel flow section is often installed in ditches or canals to measure flow rate.

    Parshall Flumes are sized by throat width and conform to standardized dimensions published in the U.S. Department of the Interior, Bureau of Reclamation.

  • H Flumes (VPC-HFL-2.0)

    Originally developed to measure agricultural water runoff, H flumes have a "V" shaped design that allows for measurement of a wide flow range. Often used to measure irrigation water, snow melt, holding pond overflow, industrial process discharge, and sanitary/storm sewer discharge.

    HS Flumes are designed to measure very small flows with a high degree of accuracy; please refer to HL Flumes for large flows.

    H FLUME APPLICATIONS:

    • Watershed Runoff
    • Agricultural Water Runoff

  • Palmer Bowlus Flumes

    The Palmer Bowlus metering flume is widely used in open channels or pipelines that are not under any pressure.

    The Palmer Bowlus metering flume has been widely used for measuring water and wastewater in open channels or pipelines that are not under any pressure. This flume is normally installed in a "U" shaped channel fed by a pipeline such as storm drains and sewers. This convenient flume requires little redesign or special modification of circular conduits for installation.

    CHARACTERISTICS:

    • Low Head Loss
    • Minimum flow restriction
    • Measurement accuracy

  • Trapezoidal - XL.png

    Trapezoidal Flume sizes are available to measure everything from an intermittent trickle to a consistent canal.

    All trapezoidal flumes exhibit similar flow characteristics and have application advantages over other flumes and weirs. VPC offers a full line of standard flumes, along with countless custom structures used for open channel flow measurement. Sizes are available to measure everything from an intermittent trickle to a consistent canal.

    CHARACTERISTICS:

    • Flat bottom from entrance to exit for better head conversion.
    • Do not require a free-fall discharge to operate correctly.
    • Staff gauge and instrument mounting brackets located within flume and factory installed
    • Natural shape of the flume mimics many earthen and concrete-lined ditches.
    • Flat floor and sloping wall allow solids to pass through the throat without being trapped.
