LCD screen displays 3 rows of information.

Functions of each button

There are 4 buttons on the device, the definition of each button will be displayed at the upper row on the LCD screen. Generally, the leftmost button stands for “Exit” or “Back to last page”. The middle 2 buttons are for users to review page by page, modify data, or switch options. The rightmost button stands for “Set” or “Confirm”. Previously mentioned definitions are only for general use. For some other usage scenarios, button definitions are modifiable for usability or error proof.

Pressing the button for an extended period will cause damage to the button. Please avoid excessive pressing.

Three-color large indicator lights

Definition of each LCD backlight color:

  • Green: Real-time data, device is working normally.

  • Orange: Non real-time data display. Set-up page display.

Frequency of data update

Due to frequent data updates for real time flow volume, data on the LED screen will update first, then data on the LCD screen. Therefore, they may have about 0.1 seconds updated time difference. between both data sets.If there are not many digits in the data, please use the LED screen for the main data.

Displayed digits on LED screen

Maximum 5 displayed digits are provided on the LED screen. If data digits exceed more than 5 digits, “FFFFF” will be displayed on the LED screen (please refer to the image below). At this time, for reading complete data, you can try to modify the units or see the 2nd row data on the LCD screen to confirm exact flow volume.

When the flow direction is reversed and the data is a negative number, the 1st digit will be a minus sign with four remaining digits.

Red: Blinking red light: Alarm A- Major error. Please see the “” page for more details. Continuous red light: Alarm B- Current status of the device meets the parameters set-up by the user so must pay attention to it. Alarm C- Maintenance Required.
