Ridgell Oil
Smart Oil Gauge®

Take the worry out of winter with the #1-rated heating oil tank monitor. Track your oil level from your phone and never wonder when it’s time to reorder oil. 

Compatible with Amazon Alexa

Track Your Heating Oil Usage

Smart Oil Gauge uses an ultrasonic sensor to measure the level of oil in your tank throughout the day. Check the app to monitor your usage and only order heating oil as needed. 


Compatible with Most Above-Ground Tanks

Smart Oil Gauge is compatible with above-ground tanks only. Compatible tank sizes include 138, 220, 240, 275 and 330 gallon tanks like the one shown below. If you have two tanks side-by-side (twin tanks), that are plumbed together, you only need on Smart Oil Gauge. 

Smart Oil Gauge is also compatible with Roth Double Wall Tanks. NOTE: a special adapter (part # CCF-906) is required to install the Smart Oil Gauge on a Roth tank. The Smart Oil Gauge is compatible with the Roth 400L, 620L, 1000L, 1000LH. It is NOT compatible with the 1500L due to an internal baffle that interferes with the sensor.

Available Adapters

The Smart Oil Gauge comes with a standard 2″ NPT fitting, which means it can thread directly into most oil tanks. If you have a Roth tank, you MUST purchase the Roth adapter shown below, or the sensor will not work properly. If you have a steel tank with a 1.25″ or 1.5″ NPT fitting, you must order the appropriate adapter below for your tank.
