For new installations, the ST106 is highly recommended. The ST106 has several improvements over the F106 including:


  • Operation from supply voltage of 12 V to 28V
  • A wider range of output types, allowing connection to any flow computer
  • An adjustable gain setting, so can also be used with helical turbine meters as well as conventional turbine
