The compact low-flow sensor 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.
Features
  • Cost attractive solution for low-flow rates and solid-free liquids
  • Wetted parts made of ECTFE, Saphir, coated stainless steel, FKM or EPDM for use in aggressive liquids
  • 3-wire system with paddle wheel and Hall sensor up to 80° C (176° F), psi: 87.02 (kPa: 600, bar: 6)
  • Frequency output proportional to the flow rate, PLC-compatible
