Time Delta C – flow meters


  • High accuracy measurement : 1% of rate
  • Superior anti-bubble performance: Our Advanced ABM method * is adopted
  • Maintenance free operation: non-invasive setup with no moving parts
  • Compact and lightweight : Size and mass reduced by 2/3 (compared with model FLV)
  • Flexible communication functions: RS-485 (MODBUS) (option)
  • Wide application range fi13 to fi6000mm applicable pipe diameters Extendable rail type detector up to fi 50 to fi 1200mm
  • Simple menu guided setup from front panel or PC interface
