The Smart Oil Gauge goes in one of the openings on the top of the tank. There is typically at least one unused opening with a plug in it (another opening is used for the existing gauge, while another is used for the fill pipe, and another for the vent). Simply unscrew the plug from one of the unused openings, and install the Smart Oil Gauge in its place.

No, there are no monthly monitoring fees.

The Smart Oil Gauge fits into a 2" NPT opening on the top of a tank. Please note that the outer diameter of a 2" NPT pipe is not 2 inches, but actually closer to 2-3/8 inches. A 1.5" adapter is available for tanks with a smaller opening.

Yes, you can check your tank level from anywhere in the world. Your phone does not have to be connected to your home’s router to view what’s in the tank.

Walk down to the tank and bring your smart phone, tablet, or laptop. Put your phone in 'Airplane Mode' and turn on WiFi only. See if you have internet access by opening up your browser. If the connection is not great, consider purchasing a WiFi range extender.

The Smart Oil Gauge can be used indoors or outdoors. For outdoor installations, the white cap MUST be sealed with Teflon tape or other means to prevent moisture ingress. Expect readings to fluctuate with temperature changes.

The Smart Oil Gauge takes two Saft LS14500 3.6 V lithium AA batteries, which are readily available online. The batteries generally last 1-2 years, depending on WiFi strength, Upload Interval, and other factors. Set your Upload Interval to 24 to maximize battery life.

The upload interval, in hours, dictates how long the device waits before waking up and uploading its latest readings to the cloud. A setting of 1 means the device will wake up and upload every hour; a setting of 24 means the device will only wake up once per day and upload readings. The device will still take a reading once per hour regardless of this setting; it just won’t upload the new readings until the interval passes. For longer battery life, a longer upload interval is recommended.

The sensor currently supports standard vertical or horizontal 138, 220, 240, 275 and 330 gallon above-ground tanks, as well as 500 and 550 gallon cylindrical tanks. Roth adapter required for 400L, 620L, 1000L, and 1000LH. Not compatible with Roth 1500L. Custom tank sizes can be accommodated as well; call 203-456-1499 or email contact@connectedconsumerfuel.com to check compatibility. Above ground tanks only.

When a tank is filled, the oil level is often too close to the ultrasonic sensor to get a reliable reading, so the Smart Oil Gauge will just say 'Full'. There is also an airspace kept at the top of the tank to prevent over-filling. As a result, a 275 gallon tank typically holds around 250 gallons when completely full.

A standard 14” or larger pipe wrench is all that is required to remove the cap from the top of your oil tank and install the Smart Oil Gauge. Be sure to use pipe dope on the threads to create a seal. Do not use Teflon tape on the threads that mate with the tank, as this could break down and end up in the oil over time. It is OK to use Teflon tape to seal the white cap in place, as these threads are not exposed to oil.
