Before Purchasing


What types of tanks is Alice compatible with?

At the moment, Alice works with the following tank types:

  • Standard 275 Gallon Vertical Tank (most common)
  • Standard 275 Gallon Horizontal Tank (looks like a vertical tank, laying on its side)
  • Standard 330 Gallon Vertical Tank
  • Standard 330 Gallon Horizontal Tank
  • Roth 275 Gallon Vertical Tank
  • 138 Gallon Round Tank
  • 240 Gallon Vertical Tank

Alice will also work if you have tethered tanks (two of the above tanks connected together.)

If you are unsure of what tank you have, look for a label on the side of the tank. Or snap a picture of your tank and email it to us at And if you have a different size or type of tank than listed above, email us and we will get that tank type set up!

My oil tank is outdoors. Will this work?

If your wifi reaches to your tank outside, then the gauge will technically work. If you received your Alice prior to January 4, 2019 your Alice is not designed or recommended for outdoor use.

The current Alice version ships with a cap on top, which protects the electronics for outdoor use. Remember to put put tank sealant (available at any hardware store) on the threads to keep water from getting into your tank.

Depending on where you live, the cold outside temperatures may limit or shorten the life of the battery. Additionally the sensor in the gauge will only work to -4F.

Is there a fee to use Alice?

Beyond the initial purchase price of the Alice gauge, there is no additional cost to use the gauge or app.

What kind of batteries does the Alice gauge use?

The gauge uses one AA lithium metal 3.7 volt battery. This is NOT the AA battery that you will find at your local hardware or big box store. If for any reason you need a new battery please contact us and we will send you one free of charge.

The gauge ships with the battery included, and the estimated battery life is over 5 years.

Can I access Alice with Alexa, Echo, Google Assistant, Cortana or Siri? Can Alice be integrated with iFTTT?

Alice is now compatible with Alexa! We are working on further integrations, in the order of the number of requests that we get from customers. At the moment Google Home is the most requested next integration. If you have an interest in having Alice connected to a platform other than Alexa, please email us at and let us know which home assistant or platform you use.

How frequently does Alice update?

The Alice gauge will take a reading automatically every 6 hours. While you are not able to change the interval, you can manually force a reading at any time by following the instructions in the link below. Note you will need to be able to physically press the button on the top of the gauge.

How To Force A Reading

What happens if my oil delivery company fills my tank to the very top and oil gets on the Alice gauge?

Every oil tank is supposed to have a “whistle stop” on it, which prevents tanks from being overfilled. And oil does not splash around during tank fills, so getting oil on the gauge should not be of concern for normal usage.

How accurate is Alice?

The gauge measures to +/- 4% at the current time although we are constantly working on refining the gauge’s accuracy.

Can it take readings when my tank is full?

Alice will read the level of your tank whether it is completely full, empty or somewhere in between.

How do I know if I have a 2" or a 1 1/2" opening on my tank?

There are 2", 1 1/2" (or 1 1/4") and 1" openings on tanks. Newer tanks will have all 2" openings, but older tanks can have any of the three sizes. Take a ruler and measure the diameter of the circular fitting on your tank. This dimension will tell you whether it is a 2", 1 1/2" or 1" opening. For sample images, click here.

How will Alice alert me that my oil tank needs to be filled?

When you set up your app, you will be asked to enter your email address. Alice will send you alerts when your tank is 1/2 full, 1/4 full and when you meet the typical minimum order requirement of 100 gallons.

What kind of internet connection does Alice require?

The gauge requires a strong WiFi connection at your tank to broadcast your data appropriately. Currently, it will only work with a 2.4ghz WiFi connection (if you don't know what type of network you have, it's likely 2.4ghz).

Why does Alice Metrics not accept PayPal?

PayPal does not report sales tax as a separate line item, which makes it difficult for us to accurately report sales tax to Maine for Maine residents.

After Purchasing


How do I install Alice?

For most tanks, you will need a pipe wrench to help you get the metal cap off the opening in the top of the tank that you want to use. This can require some good uppper body strength, as that cap has likely never been opened since the tank was manufactured.

After you have removed your old fitting, DO NOT USE A PIPEWRENCH OR OTHER TOOL TO TIGHTEN YOUR ALICE. Just tighten it with your hand. Do not overtighten the gauge as this will put pressure on the threads and may break the plastic housing.

We have recently become aware that it is against the instructions of most oil furnaces to use Teflon tape anywhere in connection with oil. So, do NOT use Teflon tape on your Alice gauge as it may void your warranty and may be against your state heating regulations. Instead, you should use "pipe dope" or pipe seal that are noted as safe for petroleum products to avoid any oil smell from leaking out.

We also suggest putting your old fitting in a ziploc bag to keep the old fitting from putting the oil smell into the air.

Sealing the Alice gauge for outdoor use or to avoid oil odors

If you are using the gauge on an outdoor tank, or if you notice the smell of oil seeping out after you install your gauge indoors, you can apply pipe sealant (also called "pipe dope") around the threads of the Alice gauge before installing it on your tank. Look for a sealant that is marked as safe for petroleum products.

Note that the use of Teflon tape around oil is not recommended by most oil furnace manufacturers. The use of this tape may void your tank warranty and may be against your state heating regulations.

I just set up my account and installed my Alice gauge on my tank, but the dashboard of the app is not showing my tank level yet.

If the gauge is successfully connected to your wifi, it will take a reading automatically every 6 hours, so you should see data appear 6 hours after installation. If you want to take a reading before then, follow the instructions in the link below:

How far down into the tank opening should the gauge go?

When you screw the Alice gauge into the tank opening, it might not go all the way down; many of our customers still have about half the threads showing when the gauge gets nice and tight.

How do I set up my Echo to work with Alice?

During the setup process with Alexa, you will be asked to provide your Smart Home Code. You will find that in the settings section of the App. This will link your Alexa account to your Alice. You will also need to go to skills in the Alex app and enable the skill "My Alice". After that you will be able say "Alexa open My Alice" and then ask "Alexa, how much oil do I have in my tank?". We look forward to suggestions from our users on waht else they would like to ask Alice. Please send suggestions to
