          Liquid crystal display

The user can switch the liquid crystal display interface through the photosensitive button:

  • First level menu is the basic measurement data display。
  • Second level menu is the reference data, such as the date, the first level address, the two level address, etc。
  •  If the water meter fails, it will display the corresponding fault alarm symbol in the decimal part of the positive cumulative volume。
  •  Any display item of the first level menu is quick to sense the light sensitive button 2 seconds, at least 4 times ,the display can enter the two level menu,Or use the factory's mobile phone reading assistant APP mobile client to enter。
  •  Factory default forward flow measurement (data is positive minus reverse data). If you need to reverse the measurement required in order to explain.

Note:

  •  The water temperature is lower than 4 When the alarm
  •  The transducer signal is lower than the standard value 30% when the alarm
  •  Battery power lower than 3.2V alarm
  • Air traffic control indicator is optional, and the default Air traffic alarm is open.
