Main Screen Menu

Screen 1: Flowrate

The first line of the LCD shows the flow unit, the second line shows Instant Flowrate, and the third line shows the flow signal on the lower left and Setup on the lower right, indicating that pressing the orange button switches to the Settings screen.

A single-bar signal indicates a poor measurement environment, while less than one bar may be caused by air bubbles or other interference. When below one bar, Noisy is typically displayed. Adjusting the pipe according to installation instructions is recommended to improve the signal.

Screen 2: Hybrid1

The hybrid screen displays both Instant Flowrate and Total Flow. The first line shows Instant Flowrate, the second line shows Total Flow, and the third line shows the flow signal on the lower left and Setup on the lower right, indicating that pressing the orange button switches to the Settings screen. Instant flow units can be adjusted in B01 Vol. Unit and B02 Time Unit, while total flow units can be adjusted in B03 Total Unit.

Screen 3: Status Page

Displays system status and diagnostics, showing Alarm A, B, C codes and the system S code. A red flowmeter indicator signals a problem requiring attention; switching to this screen allows confirmation of flowmeter abnormalities. For details, refer to Alarms and System Status (original document link retained at source).
