Frequently Asked Questions
Where on my tank do I install the Smart Oil Gauge™?
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.
Are there any monthly fees?
No, there are no monthly monitoring fees.
What size opening on my tank does the Smart Oil Gauge fit into?
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.
Can I check the tank level even when I'm not home?
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.
How can I tell if I have a Wi-Fi connection at my tank?
Walk down to the tank and bring your smart phone, tablet, or laptop. See if you have internet access by opening up your browser. If the connection is not great, consider purchasing a Wi-Fi range extender.
Is the Smart Oil Gauge intended for outdoor use?
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.
What type of batteries does the Smart Oil Gauge take? How long do they last?
The Smart Oil Gauge takes two Saft LS14500 3.6 V lithium AA batteries, which are readily available online. The batteries can last up to several years, depending on Wi-Fi strength, Upload Interval, and other factors.
What size tank is the Smart Oil Gauge designed for?
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 email@example.com to check compatibility. Above ground tanks only.
I have two above-ground tanks which are connected. Do I need two Smart Oil Gauges?
No, simply install a Smart Oil Gauge on one tank and select this configuration while setting up your account.
I just had my tank filled, but the Smart Oil Gauge is not reading full. Why is this?
When a tank is filled, the oil level is often too close to the ultrasonic sensor to get a reliable reading. Wait for the oil level to lower a bit and the readings will be more accurate.
What is the Upload Interval?
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.
What tools are needed to install my Smart Oil Gauge?
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.
I’ve changed my Wi-Fi password/installed a new router, how can I change the password on my Smart Oil Gauge?
Open the app and navigate to the My Tanks page. For iOS devices, hit the ‘+’ in the top right; for Android devices, select ‘Sensor Setup’ and follow the instructions to update Wi-Fi. The app will ask you if you are setting up a new gauge, or just updating Wi-Fi; select update Wi-Fi and you are all set!
