The compact low-flow sensor Bürkert Type 8031 with paddle wheel and Hall sensor is specially designed for 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). Cost attractive solution for low-flow rates and solid-free liquids Wetted parts made of ECTFE, sapphire, coated stainless steel, 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
