  • Stainless steel SS304 housing for the primary head is hygienic and aseptic.
  • High quality and colorless PFA liner for wet parts complies with FDA requirements.
    • Reinforced with embedded stainless steel grid, the PFA liner on the inner surface of the measuring tube has the creep
    • resistance against heat stress caused by fluids and also deformation by vacuum pressure.
  • Effective CIP and SIP cleaning without any moving parts and flow hindrance inside the measuring tube.
  • Easy mounting and dismounting from piping with ISO clamp connection as a standardized practice.
  • High accuracy of ± 0.5% of reading
  • High speed data processing for quick response. Suitable for batch process control and pulsation flow.
  • Certified by EHEDG and 3A
