    Low flow sensor

    • Cost attractive solution for low-flow rates and solid-free liquids
    • Wetted parts made of ECTFE (Halar®), Saphir, COREPOINT™, FKM or EPDM for use in aggressive liquids
    • 3-wire system with paddle-wheel and Hall sensor up to 80 °C, 6 bar
    • Frequency output proportional to the flow rate, PLC-compatible

    For selecting the correct product please refer to the technical data, images and notes for proper use according to the data sheet.

    Product description

    The compact low-flow sensor Type 8031 with paddle-wheel and Hall sensor is specially designedfor use in aggressive and solid-free liquids.The particular cost attractive measuring principle is based on a local flow velocity measurement. The sensor produces a flow proportional frequency signal which can easily be transmitted and processed. We recommend here particularly the connection to the Bürkert Universal transmitter Type 8025 (see separate data sheet).
