The office schedules the delivery to a driver on the web dashboard. The job shows up in the driver's app.
- 2
The driver opens the Fuel Delivery form
At the tank, the driver opens the Fuel Delivery form and taps Open LC Register.

The register measures the delivery
The app's LCR.IQ screen shows the register's gallons as they pump, with Start, Pause, Resume, and End.
- 4
Save & Populate Quantity
One tap drops the register's gallons into the form's Quantity field.

Finish and send
The driver adds the tank inspection, photos, receiver name, and customer signature, then previews and submits. The office dashboard moves the job from Scheduled to Delivered.

Setup
Connect over Wi-Fi
You need four things from the LCR:iQ: the Wi-Fi name (SSID), the Wi-Fi password, the IP address, and the port number.
- On the LCR:iQ, open the Main Menu.
- Select I/O Setup.
- Go to page 2 of the I/O Setup screen.
- The Wi-Fi name, password, and IP address are listed there. Ask your TankSpotter contact for the port number.
- In the TankSpotter app, open the LCR.IQ screen, tap Settings, and enter them.
While the phone is on the register's Wi-Fi, it can't join another Wi-Fi network. Use the phone's 4G/5G data for internet until you're done, then switch back to your regular Wi-Fi.
Setup
Connect over Bluetooth
- Open the Android phone's Bluetooth settings.
- Pair the phone with the LCR:iQ.
- Open the TankSpotter app.
- The paired LCR:iQ shows up in the app's paired-device list.
- Select it to connect.
Before you roll it out
What to Know Before You Get Started
The LCR:iQ connection makes fuel delivery faster and easier while keeping the familiar TankSpotter workflow.
- Android Compatible – LCR:iQ register connectivity is currently available on the TankSpotter Android app. iOS is not currently supported due to LCR:iQ device compatibility. Manual fuel entry remains available on all supported devices.
- Less Manual Entry – Fuel readings are captured directly from the register, reducing the amount of information drivers need to enter at the truck.
- Same Familiar Workflow – Everything else stays the same, including tank inspection, photos, receiver name, signature, and delivery preview.
