Feature

  • Direct reading scales eliminate the need for troublesome conversions
  • Stainless steel backbone absorbs piping torque reducing installation damage and cost
  • Shatter-proof polycarbonate allows for long operation life
  • Precision injection molding around a precision tapered pin enables high repeatability
  • Increased reading accuracy with special integral flow guides that stabilize float movement
  • Scale graduations on both side of the indicating tube allow for instantaneous flow reading saving time
