14 LCD Display Icons
The Sonata Allegro is provided with a 9-digit volume digital display factory
programmed to your specifications. The LCD also has a 4-digit rate of flow
indicator. At the time of order, you can select
• Volume units: US Gallons, Cubic Feet, or Cubic Meters.
• Rate of Flow units: US Gallons per Minute (GPM), Cubic Meters per
Hour (M3/h), or Liters per Second (lt/s). When US Gallons or Cubic
Feet is selected for the Volume Consumption units, the Rate of Flow
will be GPM.
• Alarms: Low Battery, Tamper, Leak, Dry Pipe, Burst Pipe, or
Measurement Failure (as indicated by the triangle with the
exclamation point on the lower right side of the LCD).
• Notifications: The NFC icon on the LCD will be illuminated when
connected with an NFC programming cable. Shabbat/Sabbath
mode, as indicated by Hebrew letters, is not supported in the North
American Market.
• Flow Direction is represented by a bi-directional arrow. When no
flow is being used, the two arrows will disappear, leaving a solid
black bar as indicated in the image shown. When flow is being
used, one of the two triangles will also darken creating what
appears to be an arrow pointing in the direction flow is passing.
• Network Status icon is located in the box to the right of the Rate of
Flow and is represented by a seven-segment character. See the table
below for an explanation of the symbols that may appear in this box.
• Checksum: When there is no flow through the meter, every 60
seconds the last four digits of the software checksum will display in
the Flow Rate field for a duration of two seconds. Checksum is not
displayed if the meter is registering flow.
