Return to the app and log in with your verified credentials

Already have a Generac account? If you've used Generac's website or have a Generac generator with Mobile Link, use your existing login credentials. All Generac products share the same account system.

Step 3: Install the Batteries

Powering Up Your Generac Fuel Monitor

If your monitor came with batteries pre-installed, skip to Step 4. Otherwise, follow these steps:

Locate the battery compartment on the back of the Generac 7009 LTE monitor

Remove the battery cover by sliding it in the direction indicated by the arrow

Insert 2 × AA batteries:

Use lithium AA batteries (Energizer Ultimate Lithium recommended) for longest life

Alkaline AA batteries work in a pinch

Match the + and − symbols inside the compartment

Replace the battery cover by sliding it back into place until it clicks shut

Wait 30 seconds for the monitor to initialize

Check for indicators: A small LED light should blink or turn solid (consult your quick start guide for the specific indicator pattern)

Battery tips:

Lithium batteries last 2–3× longer than alkaline in cold weather

The Mobile Link app sends a low-battery alert when batteries need replacing

Plan to replace batteries every 3–5 years with lithium, every 1–2 years with alkaline

Never mix old and new batteries

Step 4: Find the Right Mounting Location

Where to Mount Your Generac Fuel Monitor

The Generac 7009 LTE uses a powerful rare-earth magnet to mount directly on the bottom of your steel propane tank. Finding the right spot is critical for accurate readings.

Ideal mounting location:

Requirements for the mounting surface:

✅ Flat, clean, dry steel surface

✅ Full magnetic contact (no gaps)

✅ At the lowest point of the tank

✅ Away from tank legs, stands, or structural supports

✅ Clear of debris, mud, ice, or standing water

What to avoid:

❌ Uneven or curved surfaces (magnet won't fully contact)

❌ Rust spots or flaking metal (unstable mount)

❌ Areas with accumulated dirt or debris

❌ Locations where water pools or ice accumulates

❌ Directly under tank support legs

❌ Composite or fiberglass tanks (no magnetic mount)

For underground propane tanks: Mount the monitor on the exposed top surface of the tank riser or on the upper portion of the underground tank that's accessible above ground. Consult your propane supplier if you're unsure where to mount.

Step 5: Clean and Prepare the Mounting Surface

Preparing Your Propane Tank

A clean, dry mounting surface ensures the strongest magnetic hold:

Wipe the tank surface with a clean, dry cloth

Remove all dirt, mud, and debris from the mounting area

Check for standing water or ice - dry the area completely if wet

Inspect the surface for rust, flaking metal, or damage

Confirm the surface is flat - the magnet needs full contact for the strongest hold

If the surface is wet or muddy, let it dry for 10–15 minutes before mounting

Pro tip: If your tank has a lot of surface rust, sand it lightly with fine sandpaper (220-grit or finer) to create a smooth, flat mounting surface. Wipe away any dust with a clean cloth before mounting.

Step 6: Mount the Generac Fuel Monitor

Installing the Monitor on Your Propane Tank

Now mount the monitor on your prepared surface:

Orient the monitor correctly: The label should face UP (away from the tank), and the label text should be readable. This is the correct orientation-the ultrasonic sensor is embedded in the magnet base and points through the tank.

Position the monitor: Place the magnetic base firmly on the bottom center of the tank

Press down firmly: Apply firm, even pressure to engage the rare-earth magnet fully

Verify the hold: Gently try to lift the monitor - it should hold firmly without slipping

Check the position: Make sure the monitor is centered and level on the tank

Important orientation notes:

The label MUST face up - never mount the monitor upside down

The ultrasonic sensor is in the magnet base - it measures through the tank

Mounting in the wrong orientation will give incorrect readings

The LED indicator should be visible and unobstructed

If the magnet doesn't hold firmly:

The tank surface may not be flat enough

Clean the surface more thoroughly

Check for excessive rust or corrosion at the mounting point

The tank may have a powder-coated finish that reduces magnetic strength - try a different spot or use a metal plate adapter

Step 7: Register the Monitor in the Mobile Link App

Connecting Your Monitor to the App

Now pair your physical monitor with the Mobile Link app:

Open the Generac Mobile Link app on your smartphone

Log in with your Generac account credentials

Tap "Add Device" (usually a + button or "Add" option in the menu)

Select "Propane Tank Monitor" from the device list

Scan the QR code:

Use your phone's camera to scan the QR code on the back of the monitor

Or enter the serial number manually (printed near the QR code)

Name your tank: Enter a name like "Home Propane" or "RV Tank" (this helps if you have multiple tanks)

Confirm your location: Allow location access so the app knows where your tank is

Tap "Add" or "Register" to complete pairing

If QR code scanning doesn't work:

Tap "Enter Manually" or "Use Serial Number"

Find the serial number on the back of the monitor (near the QR code)

Type the serial number into the app

Proceed with setup

Step 8: Enter Your Tank Details

Configuring Tank Information in the App

The app needs information about your specific propane tank to calculate accurate gallons remaining:

Tank capacity: Enter the total gallon capacity of your tank (from the tank nameplate or delivery records)

Common sizes: 100 gallon, 120 gallon, 150 gallon, 250 gallon, 500 gallon, 1,000 gallon

The app uses this to convert fill percentage to gallons

Tank type: Select your tank type (horizontal, vertical, underground)

Current level (optional): If you know the current level (from your gauge or recent delivery), enter it to speed up initial calibration

Confirm settings: Review and save your tank information

Where to find your tank capacity:

Look on the tank nameplate (usually on the collar near the valves)

Check your propane delivery records or invoices

Ask your propane supplier

Common residential sizes: 250 gallon (most common), 500 gallon, 1,000 gallon

Step 9: Configure Alerts and Notifications

Setting Up Propane Level Alerts

One of the most important reasons to have a fuel monitor is getting alerted before you run out:

In the Mobile Link app, go to your tank's settings (tap the tank name or settings icon)

Find "Alert Settings" or "Notifications"

Set your low-fuel alert threshold:

Recommended: 20–30% (gives 2–4 weeks of warning)

Conservative: 30–40% (for heavy heating use in winter)

Minimum: 15–20% (if you're willing to risk it)

Choose notification types:

Push notifications to your phone (recommended)

Email alerts (optional)

SMS alerts (optional, great for multiple household members)

Set delivery reminder: Enter your propane supplier's contact info for one-tap refills

Alert threshold guide by season:

Step 10: Wait for Initial Calibration

Understanding the First 2–4 Hours

After setup, your Generac fuel monitor needs time to stabilize its readings:

What happens during calibration:

The monitor takes initial sonar readings from its mounted position

It learns the tank's specific characteristics (wall thickness, temperature profile)

Readings stabilize over 2–4 hours

Accuracy improves significantly after 24 hours of continuous monitoring

What to expect in the first 24 hours:

Hour 0–2: "Connecting" or "Initializing" status in the app

Hour 2–4: First stable readings appear

Hour 4–12: Readings become more accurate

Hour 12–24: Full accuracy reached

Day 2+: Optimal accuracy maintained

Do NOT:

❌ Remove and remount the monitor during calibration

❌ Expect perfect accuracy in the first 2 hours

❌ Panic if the first reading seems off - this is normal

❌ Refill based on the first reading - wait for stabilization

Do:

✅ Check the app periodically to watch readings stabilize

✅ Note the current level shown in the app

✅ Compare to your existing tank gauge (if you have one)

✅ Review the Mobile Link app's delivery history feature

Step 11: Verify Your Setup

Confirming Everything Is Working

After 2–4 hours, verify your setup is complete:

If the app shows "Offline" or "No Signal":

Check that the batteries are installed correctly

Try removing and reinstalling the batteries

Wait 2–5 minutes for the monitor to reconnect

Check that you have cellular signal in your area

Move the monitor to a different mounting location if signal is weak

Connecting to Generac Generators (Bonus Step)

Integrating with Your Home Standby Generator

If you have a Generac home standby generator, the Mobile Link app integrates your propane monitor with your generator:

In the Mobile Link app, go to Settings or Add Device

Select "Generator" from the device list

Follow the generator-specific setup (varies by generator model)

Both devices now appear in your Mobile Link dashboard

View generator run time remaining based on your propane level

What this integration adds:

See how long your generator can run on current propane

Propane low alert triggers generator-specific notifications

Combined dashboard showing propane level and generator status

Automatic alerts if propane gets critically low while you're away

This is the Generac ecosystem advantage - one app manages both your propane and your generator.

Troubleshooting Common Setup Problems

When Setup Doesn't Go Smoothly

Problem 1: App Can't Find the Monitor

Symptoms: After scanning the QR code, the app can't connect to the monitor.

Solutions:

Wait 60 seconds after installing batteries for the monitor to fully initialize

Restart your phone's Bluetooth (Bluetooth isn't used, but it refreshes the connection stack)
