display mode:

Liquid Crystal Display (LCD), as follows:

  • L XXX. X four instantaneous flow (m3 / h) or L/h
  • XX. XXXXXX eight cumulative flow (m3) or L

temperature reading

  • Cumulative flow: automatically expand the display precision, the cumulative flow values can be reset.
  • Power-fail protection: instrument coefficient, the Total flow values ten years is not lost when power supply drop.
