The monitoring screen is composed of 2 sections. The first 7 pages are real-time data monitoring. The last 15 pages are the current date, time and historical cumulative volume for the past 14 days. All the pages can be viewed cyclically by pressing the middle 2 direction buttons. Each definition on these 22 pages could be found below.

Monitoring screen No. 4 is mainly for checking the status of the device, if upper and lower limit alarm functions work as expected, or for troubleshooting there will be a red light. Please see “Description of status and Alarm” for a detailed definition.

If the password function is turned on, press Setup from the monitoring screen to modify the parameters, the following screen will appear first:

Press the bottom-right button for entering the set-up page as below.

You can switch parameter classification by the middle 2 buttons. For more details of parameter classification and definitions, please see the parameter set-up page.

Enter the sub menu, then select the expected parameter. Accordingly, find below image for display reference.

If there is a N/A on the lower right corner of an option, it means that this version of the hardware does not have this function, and you cannot enter the option.

Instantaneous flow volume and deviation

The maximum possible deviation for LORRIC’s paddle wheel flow meter is 0.5 % F.S. + 2.5 % O.R. which could be converted to the relation of maximum possible deviation and displayed data under different flow speed as seen below.

Flow speed

The data displayed on the screen is the flow speed in the T-connector. In most cases it will be a bit faster than the flow speed of same ordinary pipe at the same flow volume.

Cumulative flow speed and historical data.

Flow volume will be accumulated continuously until it is manually zeroed.

Maximum cumulative flow volume is 999,999,999 Litre and will be zeroed until it is exceeded.

Parameter C1 affects historical data and flow direction. Historical date data is set by classification G of the parameter.​

Calculation of historical flow volume is based on the following rules.

1. If cumulative flow volume is not zeroed on a certain day (ex. 2020/01/01), then the data on that day is the data at 23:59:59 minus the data at 23:59:59 on the previous day.

2. If cumulative flow volume is zeroed on a certain day, then data on that day is the data by 23:59:59.

Date data of historical flow volume is based on the following rules.

1. Recorded data will not be changed. Therefore, artificially setting a data recording date earlier than the previous one makes recorded data being the same or earlier between new and previous date.

LCD screen displays 3 rows of information.

Function 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 use scenarios, button definitions are modifiable for usability or error proof.

Three-color large indicator lights

Definition of each LCD backlight color:

1. Geen: Real-time data, device is working normally.

2. Red:

   1. Blinking red light: Alarm A- Major error. Please see the “Alarm and Description of System Conditions” page for more details.

   2. 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- The calendar battery needs to be replaced.

3. Orange: Non real-time data display. Historical data query and 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 below image). 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 negative number, the 1st digit will be a minus sign with four remaining digits.
