Monitoring the fuel dispensing by a fuel tanker
In this case, we look at the operation of a fuel tanker with an installed signal reader with a PPO fuel flow meter. The Omnicomm ICON display allows us to monitor the volume of dispensed fuel through the fuel tanker's dispensing gun and the remaining fuel in the fuel tank.
Use:
If the fuel volume goes below the threshold value, the amount of remaining fuel will be highlighted in red and a sound notification will ring.
If necessary, use the button “Reset Fuel Flow Meter” to reset the output volume.
Equipment:
- Omnicomm Profi terminal
- Omnicomm LLS-Ex 5 Fuel level sensors
- BIS-MX Spark protection unit
- Omnicomm ICON Display
Connection:
Settings:
The configuration of the Omnicomm LLS-Ex 5 fuel level sensor is performed according to the sensor's user manual.
The BIS-MX spark protection unit does not require configuration.
Omnicomm Profi terminal configuration
Run Omnicomm Configurator.
Select equipment – Terminal.
In the “Settings” tab select the “ICON” section from the list.
“ICON” – check the box to display the data from the terminal on the Omnicomm ICON display
- “Network address” – select the display network address. Possible values: from 7 to 254
- “Select the time zone” - check the box to select your time zone relative to UTC. The time zone value is used when an automatic registration of time zones is not required
“Time zone” – select the time zone
- “Sound notification” - check the box to enable sound notifications when the terminal registers a new event, as specified during the terminal's setup
In the “Settings” tab select the “Inputs” section from the list.
In the “Universal inputs” section, configure the universal input No. 1:
“Universal input No. 1” – select “Enabled”.
“Operating mode” – select “Pulse”.
“Equipment name” – enter the monitored parameter name. For example, volume of fuel dispensed.
“Pull-up resistor” – select “Enabled” when working with “open collector”-type sensors or contact sensors.
“Coefficient of pulse input calibration” – enter the calibration factor for converting the number of pulses to the determined physical quantity. Enter the value of the calibration coefficient depending on the model of the Signal pickup device and the PPO Fuel dispensing meter according to the table:
| USS variations | Use as part of products | Calibration factor |
|---|---|---|
| USS–B–70 | PPV-100-1,6; PPV-100-6,4; PPV-150-1,6; PPV-150-6,4 | 35,714 |
| USS–B–70 | PPO-25-1,6; ShZhU-25-1,6 | 1 |
| USS–B–70 | PPO-40-0,6; ShZhU-40-0,6 | 3,571 |
| USS–B–25 | PPV-100-1,6; ППВ-100-6,4; PPV-150-1,6; PPV-150-6,4 | 100 |
| USS–B–25 | PPO-25-1,6; ShZhU-25-1,6 | 2,8 |
| USS–B–25 | PPO-40-0,6; ShZhU-40-0,6 | 10 |
Press the “Save” button.
Omnicomm ICON display configuration
Run Omnicomm Configurator.
Select equipment – Indicator.
Add the parameters “Fuel flow meter”, “Tank 1”, “Tank 2”, “Tank 3”, “Total in tanks” to the screen.
When adding the parameters, specify the following values:
- Units of measurement – units of measurement for the parameter. Select the units of measurement from the list or add your own by selecting “Other”. Enter the unit of measurement in the “Unit name” field
- Measurement accuracy – select the number of digits after decimal point to display. Possible values: 0, 1
- Minimum threshold – enter the minimum value of the measured parameter
- Maximum threshold – enter the maximum value of the measured parameter
- Sound notification of exceeding thresholds - tick the box if a sound notification is needed when the value is below the minimum threshold or when the maximum threshold is exceeded
Configure the parameter display on screen as shown in the figure:
Press the “Save” button.
